Harbor Freight AC volts test: Set your HF vom on AC volts and with the engine not running test the bat voltage and see what reading you get. The meter should read zero. Some of them cheap vom testers will read AC volts when when testing a DC voltage and non-filtered DC voltage will cause them...

And like dana a says with the tire off you can get that type patch that has the plug with patch attached or a large chemical patch and then install a $15 tube if working on it yourself and the tire is not dry rotted. If not doing the tire repairs yourself buying and paying someone else is less...

You asked: I'm wondering if this could be pre OHV? Probably pre OHV. Being a Briggs 11 hp probably single cylinder L-Head, (valves in head) and the model type code will be on the air cowling tag. If it's a OHV the info will be stamped into the top of the valve cover. You do need to pull...

Can you post up a model number and serial number on that old Murray? The reason I ask is I have one and cannot locate any info. Not knowing the engine model, type and code. On yours make sure that the oil has not become contaminated with gas again and if was ran with contaminated gas before it...

Nothing surprises me now days about people.

Yes.

It crunked?(you say) That could be bad.

I think maybe I have heard somewhere of greasing muffler bearing on a bright powerbuilt 12.5 rig. May have been a You tube video??????????? I suspect the OP may be just playing with Us.

Startech wrote :Until we know what engine model/type number the muffler and the replacement muffler PN is we are only guessing at a solution. I suspect you have couple very bad MUFFLER BEARINGS that probably needs greased. Might trying filling the muffler with EP2 grease and give a test run...

Not exercising gasoline operated standby by emergency generators every once in awhile is usually what makes them not ready to go when needed. Ethanol fuel is a no-no also Before storing I usually do the following procedure so as to prevent/reduce possibility of a metal gas tank rusting and to...

When it started smoking was the smoke blue or black, like black soot. The reason I ask is oil smoke is blue, running rich will be black soot. Was the engine running smooth? Does that unit have the auto idle, where it will idle if a load is not placed on the unit and a switch set to AUTO? If...

You say: But still don't understand why oem new muffler and still loud and chokes down with ether Huh?????????what?????????? Say again????????????????? Are you indicating you are priming with ether? If so why????????????

I noticed in your last pictures that it appears that the Low idle jet still has the plastic limiter adjust cap on it even though you got it removed. If it's not adjusting for a good smooth low idle you might have to remove the plastic limiter to get a full adjust. Do not try to break the...

You need to separate the model, type and code. Appears to be maybe a OHV Briggs. Do as bert says in post #4 and then get back to us. You can find the adjustment procedure on you tube.

I would think about checking the DC charge amps. By reading amps you can see if the battery amps tapers back after starting the tractor or if the amps are ACTUALLY staying high. If after about 5-10 min's of high rpm operation the DC amps should go to 5 amps or less typically 3 amps or so with a...

What is the engine model, code type, etc?

AND dealing with whining, griping customers is the hardest part for me, especially the ones that EXPECT a lifetime warranty once I've touched their equipment. We all have seen machines that needs lots of additional work that the whiner is not even aware of and repairing their complaint will just...

As slomo says: That green corrosion not coming clean from your boiling and cleaning is also a clue that the passages inside are not getting clean plus the outside of the carb is not even cleaning itself. That green gunk has most likely hardened inside a small orifice and restricting a passage...

Symptoms of starving for fuel.

Read what scrub cadet says about just replacing the needle. Also clean the seat with a Q-tip BEFORE installing the new needle. If I find a needle that's not holding 3 lbs pressure testing first: Sometime if it's a vitron tipped needle I can take a magnifying glass and carefully inspect the tip...

Just couple hints. I've never seen that exact carb but couple hints to check. You need to remove that high speed jet that is in picture 2 and carefully look behind it to see if their are any type of passages other than straight thru. Most are just straight through to feed the lower portion of...

Yes, that is just a bowl drain. #254 Your High speed jet is the one that screws into the side of the carb in your picture 2. When you put the carb/bowl back on the carb the area below this jet to the bottom of the bowl has to be sealed good when the bowl is installed or gas will bypass this...

Post up model code type and even a picture of the engine. Did you install a NEW correct muffler?

The reason it would pull hard is hydrolock. Raw gas on top of piston. You could remove that carb and then remove the bowl and you will probably find that the float is stuck in the down position. You don;t have to rebuild your carb just turn the carb upside down back and forth and gett the float...

The radiator has to drop the water temp to less than the thermostat. You can read the top, middle and bottom temp of the radiator with a IR thermometer to see if the radiator is cooling properly while the engine is idling and the fan blowing air through. If the radiator get hotter than the...

The reason I asked is he said in a previous post few pages back he placed his finger over a leaking welch plug and it made no difference. (so he just moved on) He needs to re-check/re-seal the welch plugs especially after using high pressure compressed air into the carb.

Few pages back you said you see a welch plug leaking air. How did you re-seal the welch plug? (plugs) It appears maybe that carb has a 3 piece High speed main jet area, emulsion tube, Main jet and a high speed adjustable H jet in the bottom of the bowl. Post up some pictures of these 3 pieces...

Just curious. Are you located in the USA? The reason I ask is you say that carb is Asian and that is not a standard Walbro LMT throttle and choke linkage set-up is not normal for a USA Briggs twin? (Some of that re-branded equipment (has a JD name but parts and pieces made by others for JD) has...

Right: AS TobyU says bypass the existing pump fuel system by rigging up a gravity feed tank. If you do not have a tank as such: I have as a quick bypass of existing fuel systems is rig up a vertical piece of 1/4 inch or 5/16 tubing about 3 ft long, (tire the fuel so it will stand up vertically...

When you done your starter test using the jumper cables you confirmed your starter is bad. Those Kohler starters are good until the starter housing itself fills up with dirt and muck. Those type starters have opening at the top by the Bendix gear end and some have a itty bitty drain hole at the...

You need to put the air shroud back on that engine. (before you overheat and ruin the engine. The air shroud no longer needs to be off. Have you had the main jet out of that carb? (and the emulsion tube that is normally connected to the main jet? If so, did you look at the emulsion tube...

It's trying to tell you something and you are not listening. The gas you are installing is too high priced and it's polluting the enviroment. The mower want's to not do any work until the price of gas goes down or go ELECTRIC.

If you will take time out pull up a on-line parts list for each mower using the Craftsman model number and compare the part numbers of the tractors lift and control arms for each deck you will then have a general idea if they might fit. I've done such and found this looking at parts lists is...

Remove the rocker and compare that stud to the other one. It's either turned out or if pressed into the head it has got longer. Compare it to the other one.

Strange that both were leaking. Engine must have been excessively hot or the previous gaskets were not torqued in proper sequence and to torque specs or someone previously removed the heads and re-installed using the old gaskets. Head gaskets are pricy now days and some/most are China type.

What's the latest verdict?????????

You can maybe rig a Homelite duckbill vent. It's used in the fuel tank and fuel cap of chainsaws plus others.

Breaking news: On page 2 post #14 he indicates that the proper valve adjustment fixed his engine.

but while it revs much better without choke, the problem remains, it will only take maybe 70% throttle. ????????????Give us a hint as to how it acts when it QUITS TAKING throttle. Does it backfire, just hump up and start smothering like it wanting more gas through the carb or starving for gas...

154 hours on the machine. Is it still under warranty? Is this link the machine? could not find a 13VAV1CS009 ENGINE https://www.partstree.com/models/xt1-lt-42-13ava1cs009-cub-cadet-42-xt1-enduro-lawn-tractor-2015/engine-accessories-kohler-single-5/ Is it a Kohler single cylinder?

Need engine model, type, code info?????????

Doubt it's warped enough that it's the heads/block. Those use the thicker type head gasket. If it's the head gasket on both it's probly not been torqued in the proper sequence. You can check a head by lapping on a piece of glass, usually

Do as startech says. Use a UV tracer in your motor's oil. You can get a Automotive store. Review on-line how to use first. Be sure and get the correct type for motor oil. (not for water, antifreeze, freon, etc) Do not let the RV dry for long time once detected because it will be permanent dye...

What model and type Briggs do you have and what type pump is being used now if any AND Why do you want to try other than the OEM type pump??????????? Small engine electric pumps are expensive (around $50) and must be in the output range of 1-3 psi.

Need engine model, type, code info????????? If it starts with a prime it's PROBABLY your choke not working due to throttle linkage slipped ????????????

Need engine info, model, type, code??????????

Post up the model, type and code info of the engine. Using that model number from the tractor leaves room for lots of speculation and Cub used several different engines on the same model tractor at times so with engine info we can then maybe get on the same page as you. thanks

If we had your tractor model and deck size we might could give more precise info about your blade brakes. No need in blade brake pads if the belt is not correct because the pads will burn/wear out fast. On some rigs I've had to install addition blade break helper springs so as to hold the brake...

If that is Amazon Prime and the belt still looks ok and if it's wrong length send it back for a full refund, maybe. Usually easy to do with Prime just click on returns and go to UPS depot for free shipping. that is if you ordered the correct part number and the belt is wrong size, not your fault.
