commpression stroke stops starter

[colt54]

hello all I just had my 149 rebuilt it was bored .30 over but the starter wont turn the engine over past the commpression stroke I check all the wiring cleaned all electrical conections and have good voltage and new battery
if I take the spark plug out it turns over great valves are ajusted to kohler specs now for the fun part if its cold it will not even try to start just dies on commperssion but if I put a heater in the shead a few hours I can spin it off the commpression stroke and it works a bit better sometimes it will fire up but when you turn it off and try to restart it it stops on commpression and I have to spin it again by hand backwards so it will start again any ideas thanks

It sounds as if your compression release is not working or not set correctly
(valve lash not correct on exhaust)

ol'George may be exactly right, but you may also want to consider that your freshly rebuilt engine is still a little tight, it may just need some more run time to loosen it up.

Try hooking jumper cables from your car/truck directly to your S/G (+ to "A" terminal on S/G, Ground to tractor last hook up). If it spins very fast you can rule out compression relief and a weak S/G.

Then put jumper cables on tractor battery and use key to start. If it still spins over fast then your wiring is ok.

There are a number of variables and eliminating one thing at a time should be the easiest way get to the real problem.

you can adjust the compression release tab if you find that its the problem. it explains how to check it in the service manual. you just have to bend the tab of the comp release with a screw driver. pretty simple procedure.

ok thanks and i did the jumper cable to the starter and still would not move off compression. I was reading the manual and i think i know what im looking for for. my tractors ss is 3196222 so i can bend a tab so my guess is to bend up? and how to bend

[colt54]

thanks ol'george you were right valve lash on exhaust is way off needs to be .017-.019 heck i got .040 or more
I can see the lifter coming up on the ex valve on the compression stroke but with that kind of clearance its not even moving the valve on the compression stroke for the acr to work right
but here is a good for you I pulled the engine and carried 40 feet and down a set of stairs so i could see in better light in my basment
you just dont know how much weight you have in your hands untill you move it i will let you all know how i make out when it all back together again. thank god i got my 129 calling 3 to 6 inchs snow tonight thanks again Rod
