Was the donut valve seat installed correctly and not upside down, which can cause a different float height. Also was there carb cleaner residue in the carb when the seat was installed. Carb cleaner will make the seat swell and in some cases crumble. I am not a fan of using vacuum to check a...

Leave it to Rehlko to design an engine were you can blow it up by installing the wrong length filter. That is set up like that to prevent the filter from emptying when setting because the orientation allows all the oil to drain out of the filter.

Engine should be a GCV160LA0-S3A Up to serial number 3151054 uses carb 16100-Z0L-853 MSRP for the complete carb is $17.92. After serial number 31501055 uses carb 16100-Z8B-851 MSRP of 21.17. Need to confirm the choke is closing all the way and you have good fuel. Other than that...

The plastic intake manifold issue is something that pops up at random on random engines. Most of the time it shows up as a rough run, loss of power issue. Most of the time is effects only one cylinder. The issue can result at either head when the O ring flattens out over time, and in some...

It could be a case where the plastic intake manifold is heat warping causing an air intake leak which will effect idle rpm.

Did you use OEM Troybilt/MTD/Cub Cadet belt or generic size doesn't fit correctly belts.

About 8 ounces different in fluid in most cases. And the engine manufacturer makes the decision to how the oil is checked for proper fill level.

Depends on engine manufacturer. Kohler, Kawasaki, Honda all have the dipstick set on top of the threads. Briggs has you screw the dipstick down. I have come across a few Kaws and Kohlers were the instructions are to screw the cap on.

And even in some cases the diagrams don't show the carb kit. Even in cases where one site shows the kit, but another has no mention of those kits or the page with the carb gasket and engine gasket, or head replacement kits..

Kawasaki as well as Honda don't offer complete carb repair kits like the American counterparts. All parts have to be sourced individually.

According to the service manual for your engine the compression is supposed to be a 160 psi minumum. So part of the issue may be the compression being low. And is that 7500 hours accurate. If so that engine is way past it designed lifespan, so somebody took good care of it, Most likely...

Most push mower style engines have a molded in fuel filter inside the tank. The surging may not be directly related to the fuel filter in the tank. More likely old fuel residue or other things have made the fuel passages inside the carb partially clogged. Needs a good carb cleaning. Or in...

The main way to prevent hydrolock is don't store and tip the engine with the spark plug facing down. Any other direction for prevent oil hydrolock. But there is also fuel hydrolock when the gas drains from the carb and fills the cylinder. The little bit of fuel that runs out of the carb into...

Not sure if the simplicity cylinders are rebuildable but I know of several on JD that are non repairable.

purchase can only be done by signed authorized poulan dealer, and can only be dropped shipped from Husqvarna 2 per year. According to my distributor.

The question is does the cylinder come apart. Some of those steering cylinders on mowers are a one piece welded cap style. A good shop could chuck the cylinder in a lathe and cut the weld to separate the cap, replace the seals and then weld the cylinder back together.

Hydro drive belt came off or broke,

The trend of no drain plug started over 20 years ago. with some of the mowers not having access to the drain plug due to deck design. And with self propel like the current models you can't access the drain plug without disassembly of the underside like in your case. The oil is drained by...

I agree, but also believe that people should be responsible for their own actions. So unless the equipment failed and caused the injury the company should not be responsible. All the safety switches are there to protect stupid people from doing stupid things and blaming somebody else for...

The diagram just gives the illusion that 40 connects to 53 and looks like 28 goes between 40 and 10

Star you were not wrong assuming what you knew in the OP when you were the first reply. We didn't find out the actual model number until post 6 or post 5 if you count the overhead valve picture.

I am coming up with a 79109 deck using the 105-2473 belt

I suspect that a linkage got unhooks and then rehooked to the wrong place. That is a hydrostat mower with a fender controlled speed control, s o the belt should have no effect on the drive even if it was incorrect. From the diagrams it appears the belt is constant tension not controlled by...

Actually it does do something. Breaks the magnets that are epoxied to the outer housing rendering the starter useless.

If the starter was the only electrical component manipulated my first thought would be jammed wishbone allowing the solenoid contacts to remain energized.

The engine model number maybe etched into the side of the engine block next to the muffler. That number will get you to a parts diagram to see what parts are available.

Signs of dirt ingestion from the bottom. Looks like a ring groove at the top. No signs of crosshatching so worn .005+

The site seems to operate at random. Sometimes is works fine for a few pages and then won't load. Other times the page will go to error 500.

Briggs recommendation is the 386777-3036-G1 superceding to the 386777-0143-G1

The cable with the spiral conduit is replaced by loosening/removing the clamp to get the cable out the other plain cable that terminates through the plastic block is replaced by replacing the cable with the end block already attached. model number of the the mower would allow us to look up...

True. Dino oil with synthetic additives can be called synthetic oil.

My concern at the beginning is what is the compression reading. Above 90 then I would consider replacing the carb and see what happens.

Old outdated information. This saying is not true and may of never been true. Most of the small engine manufacturers are not even offering dino oil as an option in their own branded oil. So synthetic oil in a new engine is fine.

Most likely it is oil seeping past the rings while setting overnight or longer. And then burns off on first startup. Shouldn't happen but is quite normal for a lot of engines.

And after the first 5 years or so the internal battery to the hour meter is dead and the meter no longer works. So should be fairly accurate up to the point it stops working. Or like the one on my brother in laws CC that will randomly just restart from 0 hours.

Here is says it doesn't Q: Hi, been using the old orange bottle stihl oil for years, I recently swithched over to your stihl hp utra oil. Noticed the bottle doesnt say that the oil has fuel stabilizers in it. Does th stihl HP ultra oil contain fuel stabilizers? Joedirtbikera year ago 1...

I have never seen a 2 stroke oil that didn't have fuel stabilizer already in the bottle. So no need to add stabilizer.

Actually the retail price from a Honda dealer for the carbs on the GC and GCV engines are actually cheap. OEM carbs for around $20 and the repair parts to kit it are more than that.

I would lean toward the choke is not closing all the way. Just takes a small gap of not fully closed to cause cold start issues.

Torq head set screw. Just remember to set the clearance and then tighten the set screw. Don't set the clearence with the set screw and then tighten the adjuster nut. It will crack the nut in half.

Being that new the mower is still under warranty. And what you are experiencing is a warranty problem that needs to be fixed by the dealer. The issue is most likely the charging system on the engine isn't working properly. Could be a issue with a voltage regulator or even the charge stator...

3 things to consider. 1. running the engine at less than the recommended throttle setting can cause loss of proper engine cooling. 2. Changing the engine from the set rpm can violate US EPA emission laws. I bring this up because it related to item 3 3. Do to the changes brought about by...

Head gasket kit is 24 841 02-S will need 2 kits to do both heads even though each kit will come with gaskets to replace both exhaust and intake gaskets. And it looks like the plastic covers are the latest and greatest with updated kits that replace the metal covers with the plastic O ring...

Testing of the spark plug and coil without special testing equipment is meaningless. Try a known good plug and crank the engine and check for spark. If no spark then remove the starter housing and disconnect the wire to the coil. and then crank the engine if no spark then bad coil. If spark...

That deck is clean compared to some of the decks and mowers that come through my shop every year.

Make sure you release the pressure on the wand before trying to start. Most consumer pressure washers don't have an easy start feature therefore you are pulling over the engine and the pressure that is being held in the pump.

If built after 2012 then fuel cap is non-vented style. Should have separate rollover valve tank vent system.

Everybody from the manufacturer to the consumer is to blame for this trend. When the average pushmower is ran 12 hours/year and replaced every 3.5 years, and riders are ran on average 38 hours/yr and replaced every 4.5 years. The manufacturers are only biulding to what has become consumer...
