Yes the kill wire wiring harness on the twin OHV's has blocking diodes in EACH magneto wire. If one DIODE is shorted the ignition will be upset. First see if the engine will start with the right side plug wire off? Another test is remove the air shroud and disconnect both kill wires at the...

Just to confirm: Are all of these confirmed????? You say it appears the left cylinder is running cold and not producing power when you pull the spark plug wire? (I usually just slide the rubber plugs boot back and ground the spark plug wire tips with a insulated handle screwdriver) You have...

What model engine. Some of them old Briggs can be converted to the Magnetron ignition, no points. Just mount the magneto and don't look back.

Report???????????

What is the engine model number? Do you have a voltmeter?

I looked at your engine parts list and see that it is using a Nikki Dual throat 2 barrel carb. Setting in the drivers seat looking forward you need to determine which cylinder is dead, right or left. (you did not say which in your description? You say you have fire to both plugs and the valves...

I have two single axle lawn tractor trailers 10 ft long x 60 inches wide, one is tilt and the other has the drop tail gate. I installed/welded Boat winches on both to load non-running tractors/mowers. The tilt trailer is nice but you have to understand their limitations. (or you may get a...

Need your current engines model, type and code as already stated??????????? If that is a Briggs single cylinder OHV this info is on the valve cover. If not seen someone has installed the valve cover upside down. With the correct info We might be able to steer you to a different MAKE of carb...

Why don't you take the spark plug out a pull the rope and see if the spark plug sparks??????? Instead of just throwing parts at it possibly throwing good money into bad why not do some logical testing???? Post #43 will also give you a clue if it has any spark. You think MAYBE you have a jump...

This is a strange one for a copy and paste error????? erbay My computer might be getting a lisp or stutter????????????

Put up a game camera. Might have to lock or hide the camera or it might evaporate also. Just wondering: Are you located in or close to a Sanctuary City???

You asked me??? BTW, "erbay?" You mean ebay, right? Not sure of your question, I do not see the typo sometimes referred to as flea bay or FLEECE bay.

I have the plastic emulsion tube in my hand or on the workbench, not on the carb when installing the jets. Using the little hollow tube nut driver and the wire allows for straightening a crooked press if watched or looked at afterwards closely. Some will want to seat slightly cocked sometimes...

I've seen similar valve lift issues and the cam appear ok to the eyeballing. What I started doing is set the valve lash at very minimum .003 and leave the plug wire off or ground the kill wire. If compression is still too much for electric crank through I just inset .002 feeler gauge to take the...

I just recently stumbled across that sawzilla site. I ordered some Nikki Briggs stuff recently from them and shipping was only like $3.50 and tracking # provided and a fast shipper to me. Tip about replacing the itty bitty jet o rings. install the jet on a wire such as a straightened out paper...

One thing to keep a heads up about. Just a tip to be aware of in your description of how the saw is acting. This can happen fast and ruin your Stihl. I've seen Stihl saws do what you describe, mainly due to the H jet being adjusted too LEAN, but can be other things also. Saw cuts good if just...

Here is some info about your later model Nikki BRIGGS aluminum bowl CARB that I have on file for reference. This info will answer some of your questions about the Briggs Nikki's. Note the L in your first picture, that is the left side reference for the jets location. The texture of that carb...

The wire from the bottom of the coil is used to kill the engine by stopping the spark when IT'S GROUNDED. If the engine happens to start you will have to ground this wire to kill the engine. It will bite you if you just grab onto it with the engine running. If on a riding mower it normally...

I've seen them dual throat Nikki's do some weird things when they get upset. Do You see a Nikki carb number on the side of yours? Is that the Aluminum bowl or the Steel bowl Nikki? The reason I ask is the Aluminum bowl kit is different than the steel bowl Nikki and the steel bowl type has two...

See editing to my above post about testing your solenoid.

I know the sputtering Tecumseh engine is gone. Here is couple of links to videos of how a carb MIGHT can be modded to fix a sputtering hunting engine that is running lean. This is the basics to what I did to my HM100 Tecumseh carb idle jet. My Tecumseh carb jet was similar to the Kohler/Honda...

Disconnect the wire from the starter and see if it clicks or buzzes. A starter solenoid will SOMETIMES make a buzzing sound when the voltage to the solenoid goes low. the reason it makes the buz sound is the voltage is going up and down at a fast rate (fast pulses) and a voltmeter will read the...

Aluminum roof flashing and make a small funnel either inside the seal or on the shaft with lots of grease. That is a pain on them Briggs when the engine is still bolted down on the frame and trying to see and work overhead. Sometimes get a failure to seal. I've noticed that some of the...

Backing that jet out few turns on my engine made a change for the worse. It should make some kind of a change because it allows air to be sucked in if unscrewed far enough. and the idle suction in front of the throttle butterfly might be restricted but if so the engine would not LOW idle good...

Here is couple of links I saved sometime back about Tecumseh carbs you might review: Tecumseh carb cleaning link https://outdoorpowerinfo.com/repairs/#id_tecumseh Tecumseh carb parts link 12 2020 https://outdoorpowerinfo.com/engine_specs/tecumseh_carb_mfg_no.asp

In the picture on POST 42 the center hole down the middle of the jet is the one I used the micro bits on and enlarged by hand drilling with the micro bits. It appeared I had to drill for maybe about 1/4 inch carefully before it intersected the cross drilled hole. I think I only went about 2-3...

I've got a HM100 on a gen engine. I kept a eye and ear open for the old fully adjustable jet carbs and finally stumbled across one. The OEM non adjustable carb would cause the engine to hunt and surge when the engine was warming up and worse during temp's below 30 degrees F and if the engine...

I've seen quite a few of them plastic floats look like that, non adjustable and the carb still operate great. At first I tried installing another jet, then another float and still same. It's usually on them single cylinder Nikki's that I see such. I eventually just accepted that it's a normal...

Is this a new to you rig? You have never seen it run before??? Reason I ask is the governor is completely disconnected like someone has been monkeying with it and you said the deck spindle housing fell through the deck due to rust and age when you were inspecting, etc.??

I just now tried the link using microsoft edge and google chrome and I also clicked on the link in post #4 and all Ok??????????? https://outdoorpowerinfo.com/repairs/ Might be erratic and intermittent. thanks for the heads up

You asked: Is the plate supposed to make contact with that rod, and if so, how do I adjust it properly? YES Re-search on-line static governor adjustment. You can find such online for your Briggs Twin L-head engine. Normally those do not just come disconnected on their own. You better get the...

Now that is funny. I don't care who you are that's funny. Keep that one in mind when you turn your lawn mower key off at high rpms. You neighbors will just love you like the kids love Uncle Buck. Do it at night about midnight. (but immediately hide)

What is your latest question?

I would think that a 1-2 second miss would be hard to confirm as loss of spark when looking at a spark tester. Appears you have done about everything but swap out the mag. I'm assuming it's the electronic magneto engine and not the old model with points/condenser. You mentioned it don't start...

I'm not sure on yours without a picture, BUT On most lawn TRACTOR deck spindles if anything on the BLADE SIDE of a spindle shaft is bad, even a blade that cannot be removed I can remove the top belt pulley and take the shaft DOWN out of the spindle housing with the blade still attached to the...

Thanks for the come back. Good to see that you did not have to use more of your Duck tape to build up the diameter of the flat idler pulley. You will eventually need more of that Duck tape on the steering area. That JD machine will operate more user friendly if you will use JD Green or Yellow...

Install a correctly gapped NEW spark plug. (and do not feel bad if it runs ok afterwards) Yes leave the heads bolts alone for now they have been at rest since 1985 and good chance one or more will twist off. Your description does not warrant taking the head pull chance yet. NO NEED IN CLEANING...

Maybe in a few days, but I removed the troublesome Briggs Twin Intek OHV from my Cub with the dual throat Nikki carb that I had to constantly handle gently and fiddle with and installed a really good Kohler engine. Seems the higher in price that non-ethanol gas gets the more the Kohler likes...

They are most likely full of grease.(which is a good thing) They will turn free after they have ran for awhile. 1/8 inch in the flat pulley will still be ok. I quite often buy a bearing or bearing/pulley now days and it free wheel spins easy when new. That is a sign that China did not pack the...

Have you replaced the spark plug? Also you need to blow back through the fuel hose with the gas cap off. Some of them old Briggs had a very fine screen inside the gas tank. Some came out with the petcock and some did not. They will run for little while and shut down. (and re-start almost...

Thanks for the Plastic welding info. Been doing plastic welding for awhile. Have all sizes and kinds of electric soldering irons and tips. Some are also propane heated. I like the idea of using coax braid as a reinforcement. I have all type, sizes and kinds of coaxial cables so as to get the...

You really need to start your own post thread. The OP has not been back and probably not many watching. So you bought it NONE RUNNING FROM TRACTOR SUPPLY FOR 1/2 PRICE? (or was it running and quit you) Couple tips: I'm assuming the engine cranks over ok and fast? Remove the air cleaner and...

You need to do some closer inspecting while changing those two pulleys. I try to replace that plastic V-groove pulley with a metal type if readily available at about same price. You indicated previously that you seen the fan on the transmission pulley getting slower, which is a sign of belt...

What is this statement you wrote????????? but the V pulley turns freely but does not spin.

I told a guy awhile back that I could see the AIR inside his front tires on a small tractor.:confused: He just smiled and said I've never heard that one but they do look bad, but they are foam filled. The foam was what I was seeing in between the rubber cracks.;)

Your question: . How would I go about finding a shorter/wider belt? You do not need a part number I try two things. Go to fleece bay and type in the size belt you are considering. (for example 1/2 inch wide x 88 inches long0 search, then look at prices, then NEXT on the right side upper...

You say: There will be a day soon where I will not have the strength to do my own stuff and then I'll get the pros involved. You might keep a ear and eye open. I've heard of robot mowers, vacuum cleaners and EV's that drive themselves. Using AI. I recently heard AI mentioned on news. I thought...

What you might consider doing to get by: I heard you say you bought a correct part number OEM belt. We do not know if it's the belt slipping or the transaxle yet. You say the drive belt was hot to the touch and you could smell rubber burning maybe. You might take a piece of string or similar...

I figure when this one actually dies I'll get a new tractor. Appears You answered your own question here. 14 year old machine, 3rd owner and duck tape around the steering shaft (redneck style) to help with steering sector gear mesh. AND slipping new drive belt of correct size due to ...
