So as a update I adjusted the valves to intake 4 thousandths and exhaust to 6 thousandths. Noticed there was no spark. Checked key again replaced it. Tried to start and still no spark. Disconnected the kill wires . Fired right up and ran beautiful. No backfire, no popping nothing. I...

I did not. Like you said I am impatient. I am so tired of screwing with this thing. I do need to take a break from it. I will try it again on Wednesday (tomorrow going to bone yard and Tuesday supposed to rain). I will try to check the carb when I try to start it. This motor hasn't...

I am beginning to think I have 2 separate problems. After I adjusted valves again it sounded nice on trying to start. No backfire. It still wouldn't start. Had no spark now. Pulled flywheel again check key and flywheel. All good. Cleaned up flywheel from any residual rust. Put back together...

Only manual I have is one with parts listed and ignition wire diagram and alternator with splicers.

It only happened once. I probably didn't gap it. I think my problem is wrong gap in valves. I've set them to 4 thousandths and run engine and they are way out either too loose or too tight. I've spun the motor till the piston is all the way up. I think even though I do that it's not top...

Still working on the Briggs. I was just saying the wire harness I used was Kohler.

I do have a few things going through my head though. 1. After I put the carb back on, it ran for a few minutes I was even able to move it. Had no power at all. So next morning I checked the valves and they were tight with no play so I adjusted them. Tried to run and in starting it I ended up...

Oh the mower still runs like crap. In wiring the motor when I changed it I used the Kohler sv600 motor wire. Only thing is the color wires and swapped from what they should be. On the Kohler the fuel solenoid is a white wire and oil switch is green. Should be fuel solenoid green and oil white.

Nevermind I answered my own question

Dumb question what would happen if the oil pressure wire and fuel solenoid wire gets crossed

I. I'll let you know afterwards what happened with it

Gotcha

Even though it ran last night for a few minutes. Had no power and died as I was trying to give it gas to move back to where I had it

Adjusted valves again as they were tight. Clean the spark plugs again. Tried to start it and had lots of backfire through the carb. Even had flames at one time. I tried to check compression but my compression gauge is off. Left Bank was about 180 and the right bank was about 210. I gotta...

Everything I am finding for that engine (model 407777-128-1e) says 150 foot lbs

Yes 150 foot pounds

Well put the mower back together today and charged the battery. Got it to run for a couple of minutes then died out again. I was able to back it up and move it forward before it died. Had no power at all. I'm thinking tomorrow I am gonna recheck my valve gap. I it's supposed to be between...

Kewl thank you very much

I have the parts break down from Briggs which is the same as the one you asked me to go to. In looking at the fuel solenoid there are 2 versions of it. One built before code date 04080400. That is the fuel solenoid my carb has which is double barrel steel bowl. The id on the carb only says...

I replied it has double.

I think I figured out the problem. I'll fill in if I am right. I won't get the keyways for this motor till next week so I'll post probably Wednesday next week

It won't let me upload pictures. files are too big

1. The Kohler broke the keyway when it hit a root and got jammed. First few times I will admit I did not torque it down. When I looked up why it kept breaking I found it needed to be torqued down. Even after doing that it still broke. In the pictures that is how I found the keyway and...

As a side note in 2019 I did some work for a gentleman that fixed lawnmowers and sold them. I replaced the intake gasket on his pacifica. Anyways he gave me both the riding mowers. Neither ran. They had been sitting for awhile in a field. The troy bilt needed a new starter solenoid and the...

I'll check the intake. I am pretty sure I didn't over torque it but it is a possibility. What is driving me crazy is when it does start to run it runs beautiful but then starts backfiring and stalls and just cranks and cranks and backfires. I've had the thought of the fuel solenoid not...

Your right JB Weld failed. I used Kohler keys. When it first sheered the cub cadet ran fine for 3 years before it sheered. When it sheered I noticed then the grooves and chunk missing. Yes first time I changed the key I didn't torque it down. After that I did torque it down. What was the...

My attitude is fine. I asked for help that is all. Instead I get ripped for asking for help. Called different names and I am supposed to find with it? Yeah I have model #'s that I forgot to put in because I was a little upset with the way I was talked too.

I mean if you don't want to help them don't. Working on lawnmowers is not my profession. If you don't want to help people or call them space cadets then don't help them and I will go somewhere else for help. Thought this forum was here for help not to be called names for someone trying to...

It's fine. First off the keyway sheared by my wife hit a root while mowing. The key scored the inside of the flywheel where the keyway sits. It also broke a chunk of the shaft. Second the JB Weld was steel epoxy that has/is used in repairing issues like the one I had with the Kohler motor...

I have a Cub Cadet Lt1042 that was giving me problems. It had a Kohler SV600 20 hp motor in it. It would keep shearing the keyway. it really needs a new crankshaft and flywheel. Near the keyway is a chunk missing and on the flywheel there are a few deep grooves. I have tried JB weld to a...
