    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    Well the cams are definitely not in time and the gears are damaged from the pictured piece of metal that must have been bouncing around in the crankcase. Gear teeth are not completely missing but they are damaged on both sides. No idea where this piece of metal strap came from. Its kinda like a...

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    Valve adjustment, although much in need as the intake was way too tight, did not allow the engine to run. Did get the compression release working however. Blow back through the carburetor makes me think it is a mechanical timing issue. The flywheel pickup area passes the coil well after the...

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    Usually, with scenarios like this, I only charge for the cost of the parts. It is part of my ministry. Economics play a part, however, and I can only "eat" so much of the dollars spent. I already have many hours involved, rewiring stuff, figuring out how things go back together as this thing...

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    Thank you for the illustration. I'm gonna do the valve adjustment and see what happens. The kid probably doesn't want to pay for taking the engine apart. If I do that, I'll perform a complete rebuild. End play of .025 is acceptable. Guess up to .040" is ok. He did ask me to go ahead and change...

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    Ok....maybe I'm mistaken. I will perform a valve lash adjustment, .005" intake .007" exhaust, and see if that helps. Thanks and hope you catch a bigger catfish!

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    It is still struggling to turn over in start attempts. It fires every once in awhile, even runs for a bit. Just because I wanted to, I measured endplay of the crank/flywheel and it is over .025" which seems too much. I don't know the spec but even with a new battery, starter and solenoid, it...

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    It does not have a compression release. The engine data label is worn off and I don't have that information. Upon further inspection, I found that one of the valve guides had moved. Remedied that and now I have valves fully closing and 120 psi cylinder pressure. Top case bolts are tight, read a...

    They should probably rename this engine: Kohler 19 Dis-Couragement..

    Troy Bilt Mustang Colt ZT: Kohler 19 Courage

    Trying to help a kid out who mows yards. I've read all/most of the discouraging facts about this engine. This one has zero compression despite the piston moving in the bore and the valves working. My guess, as I have not taken the engine apart, is the rings are toast, the valves are burnt, head...

    D140 Surging

    Comparing the original carb idle jet i.d. (.060) and the replacement carb (.025) I've confirmed what several of you have posted. I did drill out the idle jet of the new carb to .060 with a pin vice and drill and the motor ran better but an issue with the needle and seat prevented calling this...

    D140 Surging

    I am certain the gaskets are in good shape and there are zero air leaks. I am going to check the fuel line from the tank and the in-tank pickup, valve setting and governor setting. After more reading and knowing that the tractor runs ok with a load, I am fairly convinced the idle jet is too...

    D140 Surging

    I'm gonna pull it back apart tomorrow and see if something has gotten through the new filter and into the new carburetor. I did not mention that immediately after replacing the carburetor, the engine did not surge and ran through the throttle range very well. It was after I'd parked the mower in...

    D140 Surging

    Not sure what altitude is regular and what is high but I'm in middle Tennessee so.... This was the issue before the carburetor replacement. Regardless, I guess I didn't know different jetting was available for these carburetors.

    D140 Surging

    M# 44N677 Type 0001G1 Code 150526YG 22 h.p. I also checked compression/cylinder pressure and both cylinders are right at 120 psi. Carburetor is new but I guess a piece of crud could be in the new carburetor.

    D140 Surging

    Guess it is a common issue and I've read several posts and watched several YouTube videos. V Twin Briggs in a D140 John Deere. I've replaced the carburetor along with new gaskets, fuel pump, fuel filter, air filter. Thought it might be a restriction in the fuel line from the tank so I ran the...
