Bought engine used so I do not know history. Noticed hole in exhaust side plate so replaced it and the inner plates
which were very pitted. Had to rebuild starter, it was very corroded internally, Removed and rebuilt both carbs. They didn't look too bad though. Replaced the water pump since didn't know history, It also didn't look too bad.Tried to start it. Can get it to fire up and run for short bursts if I squirt starter fluid in the carbs. It will not stay running.
I checked all four plugs and they are firing. I checked compression and have 150 psi in top 3 pistons number 4 is only 90. I removed fuel line just in front of carbs and get gas squirting out when I crank it. My though was no gas. I tried to check timing but noticed the marks on the top crank seem to be about 1/4 turn off. I looked into piston 1 with plug removed and when it was at top I put a mark on the crank. Then when using a timing light on #1 it was firing close to the mark, so assume it can not be off that much and that the crank gear must have been removed a tsome time and not put back on correctly. One other thing I tried., while cranking I put my hand over one of the carbs thinking that would fource the enginene to suck gas. The suction was not that great, and the engine did not start, though it seemed to try at a few points. When puting your hand over 4 cycle engines I have noticed quit a bit of vacummn. Not sure about 2 cylce enginses. Any ideas?
