If it is just homeowner occasional use, Ryobi does pretty well from what I have experienced. I do not recommend them for commercial use because they are just not that built for that. The advantage of battery power tools is no mixing fuel or dealing with tune up. The disadvantage is the...

Hello G., Welcome to the forum. What we need more than a year model is the product information number (PIN) label information off of the chassis. The label in on the front side rail on some models, but many of them have the label hidden under the fender between the tire and frame. John Deere...

Hello Skippy, Oh No! Not the "evil Zinc" .... Just another scare from an uninformed individual who has been misled by rumors that Zinc is some kind of "destructive" additive in oil. The dealer of all places should know better, but people are quick to believe bogus rumors instead of reading the...

Everything points to a broken ACR.

Hi Dale. Unfortunately, the copper clad coil windings in newer coil designs (for at least the past 25 years) tend to break down at a faster rate than the older 100% coil windings designs. They cannot take the continuous high heat cycles.

That is the fuel solenoid I was referring to. It is also called and anti-backfire solenoid. It keeps the carburetor from sucking in fuel after the ignition is cut off but the motor is still spinning due to inertia from the flywheel. Raw fuel gets sucked in and travels through to the hot muffler...

Hello S., Please provide the Product information label information off of the machine chassis and off of the engine label. There were many of these built and there were changes often made during production. That faint click you are hearing is the fuel solenoid activating when the key is turned...

Regardless of how much we like or dislike the changes, battery powered equipment is gradually becoming the norm. I've worked in the mechanical/ small engine/ farm tractor/ automotive industry for most of my career and started out with simple hand tools and a few air tools. Without a good air...

Hello F., It's known as repurposing with minimal engineering design changes. Have you ever wondered why same make/brand mowers could be found with different engines and look practically the same? As battery technology advances to provide longer run times and power, I still have to wonder...

Welcome D., We will need the product label information off of the chassis along with the engine product label information. This reduces people guessing and having run-on postings

Welcome fbirch, Please keep in mind that if you need help with an equipment problem, we will need the chassis label information along with the engine product identification label information. Many machines were built with early/late serial number breaks and can be engineered quite differently...

Hello T., Was the engine starting and running fine before the "filtered fuel" was put in? I used my Mr. funnel quite a bit without issues until I accidently ran over it with my service truck. If the fuel was aged, it has lost most of its volatility. I'm not sure if the funnel has a "shelf...

Sad that someone welded the pulley. These come apart from the top after the nut and pulley are removed. Cutting that weld will likely destroy the top of the shaft along with the pulley. You might get lucky by drilling 1/8" holes partially through the weld and break it free, but it will have to...

Hello J., Everything is quickly becoming poorly made "copycat" versions of each other. All of the original SE manufacturers have contracted out or sold most of their designs to the free market because the patents have expired. What I see in my area is a lot is Honda clone engines that are...

Thanks V., Star Tech sent me a link to the same. I've been looking it over while waiting for the head kits to arrive.

Hello C, The tool you described is often referred to as a vibration/frequency tachometer by some folks like me. I've had mine for 40+ years. I never can recall the German name of it. It is a simple device that works very well for reading the RPM on small engines...

Everyone wants to create confusion these days. It's all about the money and who can claim ownership.

Sad to say, a "Barn find" usually means a badly broken-down machine that needs lots of work or it is a parts machine. These are not a "miracle restoration" find most of the time unless you want to spend money on them.

Hopefully the coils have not been overheated by the excessive gap for too long.

Recheck your battery installation and clean the cable ends a battery posts. New batteries often have a gray oxidation on the posts.

Also, don't neglect the oil filter. It is worth the money when changing the oil.

Hello C., These engines run at a fixed high RPM of about 3400 RPM as I recall. They do not have a throttle cable to regulate the engine speed like the older mowers did. You might try hitting the primer bulb just once when hot to see if that helps. Otherwise, the primer bulb and the air...

Hello Newbie Jules, We need the product label information off of the chassis of the mower.

Hello M., Welcome to the forum newbie. Anytime you need help with your equipment, we need the chassis product identification label information. If a problem involves the engine, we will need the engine product label information also. Otherwise, we are just guessing and that could easily...

Do you own a test light and a multimeter? Some engine and chassis numbers would be a big help because crystal ball is not as reliable these days.

Hello Folks, Keeping equipment "at the ready" is something I had instilled in me year ago. I grew up in the mountains of Virginia and recall when we would drain or siphon/pump all the fuel out of equipment for our cars and trucks then run the equipment carburetors dry and store them for the...

A 5-gallon bucket with a few grains of cattle feed works nicely. The cat knows right where to find them after a couple of times of getting them out.

WAG The vacuum pulse pump is not working properly, or a fuel supply line is collapsed or blocked internally. Fuel lines typically fail from the inside.

Hi Star Tech, Sticky intake valves in the guides? Similar problem like the Kohler twin I'm dealing with right now? Just a thought.

Hi Star Tech, We had a "Blue Northern" 20-degree temperature drop in the past 24 hours. We went from the mid 90's to the 70's in the daytime and upper 40's at night. We don't get many slow seasonal weather transitions here in South Texas. Thanks for the bulletin. The #2 head kit came in late...

Hello H., Yep, once I added up all the separate parts prices (and shipping), it made more sense to go with the head kits Everyone seems to think every little part is gold these days. Of course, a complete replacement engine is not cheap either.

That is the deck drive belt hanger that attaches underside just behind the main engine drive pulley. These are used on lever type PTO operated deck drives and prevents the belt from jumping off when the deck is disengaged. Looking at the worn hole, it has been loose for a while.

I cannot believe I am reading some of this stuff. This has "ethnic engineered" written all over it. Determined to make it work no matter what? What's next? A piece of tin, some self-tap and more RTV to cure for a few days? Any new gasket, or just resealing what's there?

Hello J., Mix up some Acetone and transmission fluid (50/50) and wet it down lightly for a couple of days. Keep the mixture in a jar with a tight lid if you can. Then try loosening the square head bolts, first, carefully. Once you can get them removed, put a few drops of the mixture in the...

Hello C., First problem I would look for is the upper-case bolts under the edge of the flywheel are backing out. They will rub against the flywheel and also crack the engine block in the front if they are not caught in time. The engine factory failed to put Loctite on them during engine assembly.

Thanks Star Tech, I have a fairly good library, but every now and then I get a unit in that I just don't have the needed specs for.

Hello H., Valve springs collapsed, rocker studs backing out and both intake valves very badly stuck in guides due to suspected bad/contaminated fuel being used. The part numbers for the heads have had 3 different revisions. I figured that I am better off going with the Rehlko/Kohler head kits...

Go to link, use left drop down on page for wiring schematic, click on that to open then expand the schematic so you can see how the wiring circuits connect. Hopefully you are not using Amazon generic switches...

I have a Kohler PT-KT735-3077 engine that I am getting ready to put a set of new factory heads on and would like the most current engine repair information if anyone has it in the library or links available. I've check mine and do not have it. The heads will not likely be here until next week...

Time to start looking for an older core engine for the cam. I have had to do that a couple of times for different model engines. Plastic cam designs are just another factory engineered failure point that people do not expect. The industry is trying to do away with small engines, especially on...

I agree GearHead36, Most are built these days to barely make it 5 yr. with even good service. The "Green Power" lobbyists are trying their best to abolish gas- and diesel-powered equipment as fast as they can. Apparently, they are ignoring where all the high-tech battery waste is going to go...

Look it up by the information on the engine label and see if there is a replacement steel cam offered.

Hello rs334, We need the information off of the valve cover or stamped into the metal fan shroud. Some engine had the numbers etched into the flat side of the engine case on the opposite side from the carburetor. There were many of these engines built with these basic dimensions but customized...

Hello H., I only consider auction equipment for needed hard to find parts most of the time. Most of the stuff that no longer runs ends up at an auction usually because they have major non-running issues. Ive only been lucky a couple of times on some of the ones that looked like they had...

Coil kill wire diode gone/going bad? Unplug the coil ground lead to see if problem still exist.

Hello Newbie Hawk Eye, Whenever you need help with an equipment problem, please provide the product label off of the chassis and the engine. The equipment manufacturer does not build the engines for their equipment. The more information you can provide, the more accurate answers we can provide...

Hello B., The only warranty I would advise on used equipment is to have a buyer thoroughly test run and cut with the machine while I am present to confirm everything is in good working order. Once it leaves my place the "warranty period" is over. I have an area designated for "test runs and...

How much will anything sell for? It depends on how much the buyer wants it and is willing to pay at the time. Cash is what most sellers want, not financing headaches. The one problem I see much of the time is people think a credit card or a bank check is the instant solution to spontaneous...

hello C., Go to the Champion generator website and look for their load wattage calculator. It is a fairly generic list of items that are common with most households. https://www.championpowerequipment.com/generator-wattage-chart/ I usually find out the running wattage of an item (on a label...
