I have been working on this thing off and on for over a year and the thing is still not running. I started into it last year hoping to be able to use it as a plow for my driveway. I still can not start it. To make it what I t hought would be more reliable, I replaced the following: gas tank, spark pl ug wires, spark plugs, distributor (I broke the tang on my old one), coil, points, fuel bowel, etc. I checked the timing twice.
I rebuilt the carb and installed it this weekend. It started for a minute h olding the choke in but then backfired and died and could not restart. (The few times I have gotten it to run in the last year it would run for a minu te then backfire violently and not be able to restart). I bought a new carb from TSC as a last ditch effort yesterday. Still no start. Using an old sp ark plug yesterday grounded to the engine it does fire. If I crank on it lo ng enough it acts like it fires for a split second because the starter dise ngages but never takes off. I can feel suction on the throat of the carb wh en cranking, however, I am not so sure the spark plugs are getting gas. It will not start when spraying starting fluid in the throat of the carb. I do n't think spraying starting fluid in one of the spark plug holes and reinst alling the spark plug made a difference either.
As a last ditch effort, I checked compression with the throttle control wid e open and no choke. Of course the engine was cold as I can not get it star ted. The following were the results I obtained:
1= 85psi 2= almost 90 psi 3= almost 90 psi 4= almost 80 psiI then added 5w30 (all I had) motor oil into the spark plug holes one at a time. I probably used too much as I poured from a quart container, the spac e was tight, and it was getting dark. The following readings were obtained after the addition of oil:
1= 120 psi 2= 130 psi 3= 105 psi 4= 95 psiI did notice after doing the wet test, oil was coming out of the carb thro at.
I replaced the intake exhaust gasket last year because it had a leak.
I am just so frustrated and not sure what to do at this point.
