If one of the push rods is down in the engine sump. the bottom of the engine will need to be removed to retrieve the push rod and/or parts before they cause more damage. I have seen push rods get wrapped around the cam and break the compression release. You will need the crankshaft seal and...

A replacement engine will be in the $1K range more or less. A new rider will start at $2K and go up, so have to decide from their.

It may not knock even if one rod is broke. And a missing push rod will prevent it from running on that cylinder. Intake push rod won't normally cause a popping noise. Sometimes the exhaust valve push rod missing can cause a popping back through the intake, but not always.

Remove the spark plug and turn the engine over slowly by hand and see if that piston is going up and down. Remove the valve covers and see if the push rods are still in place and not fallen out.

Here you go. It is an Murray made by MTD manuals https://www.mtdparts.com/en_US/prior-year-models/murray-riding-lawn-mower-model-13an77ss058/13AN77SS058.html parts https://www.partstree.com/models/m-175-42-13an77ss058-murray-42-lawn-tractor-2019/

@trooper1954 I think the diagram is somewhat misleading They show the washer going on before the adjuster wheel mounting plate, but the washer will not fit over the part that screws into the wheel mounting plate

On the Kohlers you can full choke cold start them with a failed fuel solenoid. I have seen it more than once in my career. I have even limped them into the shop. As soon as your open the choke they die, but will run roughly on full choke with the solenoid either not energized or stuck shut.

Here is a picture of the 110-7191 that we are saying is the correct part. You can compare it to the washer in your picture They look identical to me.

The afterfire solenoid has no effect on the float valve, or fuel flowing into the carb. So as the fuel in the bowl evaporates it will be replaced with fuel from the tank in a gravity flow situation. If the float valve fails the carb will still overflow and flood the engine, The only purpose...

Here it is on the Toro parts website item 15 https://www.toro.com/en/parts/partdetails?id=48721&iid=454794&pid=501829

They maybe calling it a thrust washer item 15 on this diagram https://www.partstree.com/models/20374-toro-22-recycler-walk-behind-mower-sn-402090000-403499999/rear-wheel-and-height-of-cut-assembly-13/

I don't know if your have a Briggs engine or not but some have a plastic tip on the fuel solenoid in the carb bowl. Have had a few were the tip would come off and shut off the engine. You could turn off the key and back on and it would start and run for a period until the tip would come off...

I think you misunderstand what was being discussed. The 1/8 inch was not the valve clearance gap but how far the cam lobe lifted the valve when it opened.

Actually it is NOT. A fuel shutoff solenoid shuts off fuel flow into the carb. The afterfire solenoid doesn't effect fuel flow into the carb or the fuel bowl, and won't prevent the carb from overflowing if the float valve fails, only stops fuel from being drawn into the carb venturi to help...

After looking at your parts diagram it appears that engine has the Kohler Command with the solenoid shift starter. It could be just the starter bendix not fully engaging which would prevent crank and the clutch issue could be a separate issue. Or could be really serious and the engine or...

Fuel flow restriction going into the carb. And the engine is running long enough to drain the fuel bowl on the carb. And wlll probably restart after a few minutes when there has been a little time for the slow flow to refill the carb.

When looking at the parts diagram for your mower it appears the diagram doesn't match the parts on your mower. It looks like the pinion gear in your picture has 2 flat sides and locks to the shaft, where as the pinion gear in the diagram has a 4 sided keyed hole set up for a slipper style key.

Battery not charging and the electric clutch shutdown after the battery got low enough, and now doesn't have enough lightning bolts left to crank the engine.

People tend to use coil and ignition module interchangeably but are not the same thing actually

MTD and JD do not use standard width or length belts. And cannot be substituted because they will not work properly or get damaged in a short period of time. And since you are describing the 2 belt system then you also need to replace both belts at the same time or the system won't sync the...

Sheared flywheel key in this won't prevent spark. Would effect starting and running but will still produce spark.

Technically it is a CDI. The new style briggs ignition modules are Capacitive Discharge Ignition.

Or the wheel motor has seized. Have worked on this exact model where the wheel motor would seize after getting hot. Jack up the left side and see how well the wheel turns. may have to activate the pump bypass to check.

1/8" valve opening is about half of what they should open. And I currectly have 2 OEM cams on backorder with an ETA of October.

And that was based on the idea that synthetic oil wouldn't allow the rings to wear in properly to seat. And the truth is most engines are using synthetic straight from the factory. Doesn't matter if a lawnmower engine or your automobile engine. Most are coming from the factory with synthetic...

Does the throttle in the carb move freely without binding. If so then I would honestly say the governor gear inside the engine is roached.

If you watch the video the tach is showing 4660.

And just to add to Tiger if it is the carb with the metal fuel bowl, don't figure the bowl nut because that is were the main carb jet is located.

If not a Briggs carb the aftermarket carb could be suspect. Also an intake air leak between the carb and were the intake pipe connects to the engine block could cause lean issue. And third an issue with the governor. If you hold the governor steady to stop the surging how does the engine...

Loping or throttle surging is normally caused by a dirty carb that has idle passage in the carb clogged. If you engage the trimmer head does the loping go away or no different

Looks like the carb and air filter housing are moving around. Are the carb mounting bolts tight. If they are loose will cause an air leak which can effect engine rpm. If you disconnect the governor spring what does the rpm's do. They should go to idle if the governor is working. If it...

1.3 converts to a .050 gauge bar. If you are just replacing the bar and have 80 dl chains you want to continue using, then you need a 80 dl bar. If you are replacing both the bar and chain and don't have extra chains that you want to use then you can purchase the normal 78 dl bar and 78dl...

And if I replace the coils the problem goes away. See it at least once or twice a year. And in your scenario the coil that is still connected to the ground wire would still not have spark. But if I disconnect one coil they both will have spark including the one that should be grounded through...

So what is happening when I disconnect a kill wire from either coil, and both spark, but if you reconnect the kill wire to both coils neither will spark. Or have the engine running and ground one spark plug wire and the engine dies. Restart the engine and ground the opposite spark plug and the...

Crosstalk diode in one module failing can potentially shut down both modules. Wouldn't be the first I have seen on Kawasaki engines. And we don't have the spec number for the engine or what brand of equipment it is mounted on.

Are both valve opening the same distance. I have seen one cam lobe wear down causing similar issues with rpm and running.

Shuts off all at once leads me to think the issue is not fuel related but more igntion related. Loosing spark when something gets hot.

The sprocket will be specific to the saw, but could have the option of a .325 or 3/8 pitch sprocket. Now bars can get more complicated due to different lengths and different gauges. The chain pitch, gauge, and drive count have to match the bar. So a .325 pitch with .050 gauge( drive link...

When it shuts off does the engine sputter and run rough before dying or does it die like the key was turned off I am wondering if it fuel or spark related

The model number the OP put in the original post is an L head engine.
