We have had a warranty repair with similar issues which was the drive controller.

So in our shop, we work on anything I can get in the shop. We are a bit more electrical savvy as rotable rebuilders (starters, alternators and generators). Because of this open attitude, we do get some jobs referred from other shops, over 100 OEM's we are authored for, and nearly all generators...

The color f the spark tells you about the weather, not the value of the spark. Spark jumping the proper gap is proper spark but I suspect your flywheel key is partially or totally sheared changing the timing of the spark.

I agree with prior info but wanted to add some feedback. The reason to run the engine at full throttle is a faster and therefor greater hydrostatic pump volume to do the work. That means the foot pedal slant will move less from neutral which drastically reduces Hydro motor wear. That said, in...

I do a lot of biz with them and immediately wrote my complaint and warning that I will be looking to source changes. I have been with Stens, Arrowhead, J&N, for a long time. Since AH bought the others out, the changes have been ok till now. Hell, I was buying from Ariens before they sold out to...

Most of the above is a good round up, but I have to add my most significant belief. Assuming the engine was running or recently shut down hot in your video, we have hot fuel boiling, or more commonly called vapor lock in a pressurized system like on cars. Since a gravity feed, two causes of...

An inline detection of the coil / plug will most likely show a missfire. Now to find the cause. is it the plug - try another new one. inline at output of coil to high tension lead - replace wire if not seen coming out of coil. If seen missing coming out of coil _ dada - replace coil.

I have one that we spent 13 hours removing it in pieces. I wish OEM's would use never seize on these. It came in pieces and I suggest you order one now. I redirect prior comments in this fashion. 1) get a can of freeze 2) EVEN A PROPANE WILL HELP 3) heat pulley then hit crankshaft with freeze it...

same 3 times this spring - put gas in a unit here to fix, it starts and runs - what a surprise!

I would bet $1111111111 this is the answer to your problem. Adjust the valves. You can get the manual for your engine.

stuff under deck preventing blades from freely moving. to change the sticks center point, an adjustment of top half of sticks versus the bottom where by you do not change the bottom but move top where it is comfy. Ignore the noise except under almost all operation, engine at top speed. Exception...

I put my money on that cheap carb. Not money well spent and often a mis match part with incorrect jetting.

Part of the problem is just that, insufficient or inaccurate diagnostics and symptoms up front with little identity of product. Hard to get these facts clear in writing. In fact the first post needs to be precise for me to bother unless I see a train wreck in the responses

So wrong to give this advise. in fact engines are made cheaper by design by using ACR or a cam lobe pre TDC lift so that a cheaper battery and starter and smaller cables and charging system can be used. If no compression release is done the system will have a very hard time cranking past TDC or...

It is not all cost. A few years back, B&S production was sold out for a year and a half and left many Chassis OEM's hunting for engines. In the years along that time, seeing a market to fill, many new options sprang up and China was a major filler of the holes in needed production. They...

for you sake, I am hoping the push rod is either bent and not making contact to tappet or not seated on cam, off to the side resting on the block passage to tappet, otherwise is suggests there is a cam problem. Pull push rod out and check for being bent. Look into engine block push rod passage...

to convert to gasoline is a mistake in my opinion.

I seldom have to revert to blind replacement. As advised, buy the manual. Do some diagnostics, symptoms tell us many possible factors, diagnostics traces root cause and until root cause is found or fixed, no solution will happen and blind replacement may aggravate or cause more problems.

B&S has lawn mower engines today that do not recommend oil changes over the life of the engine. I agree, as long as the level is maintained.

The red circle is the location of the drain plug. Also, synthetic oil is over kill and wasted money in my opinion. Low oil casuess damage but in 50 years i HAVE ONLY SEEN 1 engine damaged from poor oil changes and that was caused by oil port pluggage.

O My income loves ethanol. Repeat or returns are a problem because they get it home and add water, I mean gas to the tank and expect my effort solves everything forever.

Are you mulching? If so, let it discharge! If not, then check the bearings for each blade and each idler pully. Remove the belt and feel the bearings as you slowly rotate the blade or idler. Third, check the belt routing. Forth, if the clutch is the adjustable kind, an air gap is usually...

The instructions on those kits tell you if the flywheel has two magnets, out are out of luck, a weak spark incorrectly timed will result.

Once a welch plug is removed and reinstalled with a new one, seal the outside with nail polish. Nail polish will not dissolve under petroleum products. I use guitar strings as fine wire cleaners. To determine the root cause of a hunting operation, hold the throttle at various moderate settings...

I have serviced 50 or more in my many years. I suspect the top of the tranny has it's shifter mechanism high and every older unit I have opened for these conditions I find the corrosion on the shifter and it's ball detent. I later after learning this applied penetrant liberally on the shifter...

Over the last month, I have estimated about $6500 would have been saved or not spent trying to fix an issue rather than have it fixed. Remember repair shops do exist! Support your local shop. You may even find some very relevant support by asking some questions.

Wow! All this help does not start at the beginning. First, does it have a fuel shut off electrical device on the bottom of the carb? Is it quitting because of an engine problem or is spark shut down and it quits suddenly? When it quits does it sputter and stumble or simply quit firing? Does it...

When you say oil slinger, I assume you mean the governor, not the rod extended oil slinger on end of rod!

As already stated," first lets start with..." B&S has a simple online method to see what they offer, and I bet it is easy but .. is it a house, a horse, a car, a plane? Match what?

Valve seat is a definite possibility but more common is valve guide migration. Once they move from overheating, if in or out, either way complete valve travel will not occur, thus setting the lash will do no good. This happens far more often than seat in head coming loose. The best fix is buying...

I believe I have them in stock. To my knowledge there was only one part number for the spring/slot keys that engage into the appropriate gear when shifting. I refer to them as shifting keys.

Anybody can buy a B&S engine and put it on a poor product. Likewise, more China stuff out there than anyone knows. I also learned that some China produced engines made for various US brand names where black marketed to various OEM's without knowledge or valid US serial numbers by China. Get...

search for about 4 replies about a hard to start that I replied the fuel solenoid will not retract under 12 volts when cranking.

Another possible issue is higher load starvation. Fuel flow limited. Could be the cause of a sticky fuel anti after fire solenoid, the electric device on the bottom of the carb. It shuts fuel off with the key off. If it does not move fully, it can starve the engine. Also a sticky needle and seat...

When it comes to gas these days, we have all seen everything. algae, mold, metal forming oxides, plastics and rubber decay, and far more. Ethanol and additives and time are the enemy. If it runs on gas, in time problems will evolve unless it is dry. A few years back I had conversations with the...

In most cases, bending the throttle cable would be the wrong thing to do. Most times, the cable clamp must be loosened and allow the cable to move the linkage to full position for full choke. Engine max rpm is controlled by the governor. It might rev higher when you move the cable clamp but, if...

An important question was not answered and this is why it is important. The nopise could be a "simple" idler pulley that tensions the belt or the tranny. In neutral, let the pedal up and if the belt now in motion is spinning these ( or this) pulley and the tranny input shaft is spinning but...

We have seen 8 new carbs not function straight out of the box, mostly as a parts issue - storage. Ethanol is a solvent, not well liked by rubber tipped floats. We have added Marvel's mystery oil in our fuel treatment as a lube to valves, float needles, and rings. This has helped greatly. We also...

Also have a nice day. Glad it's good to go. Did not say you had no idea, you just did not tell me any diagnostics. A picture of me is not me - likewise a picture of a carb that looks like what you want to replace is not necessarily the same. Just tried to help as that is the goal here. When I...

OK - do what you want. ANY Authorized Kohler can do this or provide the proper parts. Most any repair shop can also order the correct part, but trial and error without the proper part number is what you want to do - I get it. It's to hard to get the model number and call a local dealer and get...

Just buy the correct carb - if the carb! Like already said - what diagnostics has been done. Many carbs are same appearance but different performance. Find a kohler dealer or on-line buy THE part to avoid issues. Also, why not stop and have a warrantied dealer fix it?

A copy of the old Speedex design.

bent, burnt or sticky valves - note intake must be open or timeing off when flamess come out carb - period. the other factor is a little harder to determine - a migrated valve guide that prevents the valve from proper travel or the rocker arm from proper travel, as the guide can migrate in or out.

model and type please if you want help. Also, I do not believe any had tree magnets, only 1 or 2 on the very old machins with points, other wise one. Ther are counter weights that may look like magnets and may have taken on some magnetism, but not part of spark system.

Timing is done with an offset dial indicator to piston .080" but I cannot remember if before or after TDC. Can be done with head off and normal vernier since I am probably one of 10,000 shops that still has the special tool to stick in plug hole with ofset shoe to measure pistoon position...

Made by Poulan and now under Husqavarna sub devision HOP and NLA.

There are firms that rebuild automotive clutch plates. They can make the part if you can find the right company, otherwise it's a hunt for NOS on Google.

But first, they will get you in biz for no investment and no cost and free education, and a free sex change. This only applies if you don't work.

Wow, this is an experienced report.

Everything I can add has been discussed except, under higher load and greater air flow, a wet air filter or air box might then add water to the combustion. I do put my money on blown head gasket.
