I've been slowly restoring this motor for about a year now. Although it was running when i got it and I've been using it pretty regularly for the last year I still cannot get it to slow idle.
Carb has been cleaned and rebuilt timing adjusted, new point, condesners, coils, plugs and wires. The motor is a little cold natured and very sensative to starting procedure. Once she warms up it is a one pull to get it going. It does run full out pushing a 14' jon 25mph. On the other hand most the time if you punch it, it will hesitate until a certain rpm then really start making some power. Usually about a 2.5 second where it seems to splutter.
The only thing that I haven't done is to take the cylinder head off and clean and inspect the the whole area. So i started in on this today. One bolt was a booger but finally I got it off. When i pulled off the head first thing that got my attention was the fact that the top piston was eaten up. Maybe that is alittle misleading but on the front of the piston where there is a little horseshoe type ridge that definatly had some kind of damage. From what i have no idea. Around the top sparkplug hole on the inside were some metal deposits. Other than that the pistons and cylinders walls were in good shape, no scowering. The gasket was in tack but there were some areas that were swollen,?, on the head side.
I cleaned everything up will a wire brush, wd40 and cloth. I've got no clue what the compression is and no tools to check it with. I'm going to assume that it is ok b/c of the LACK of scowering, get a new gasket and go from there.
Any ideas on:
What to do from here.
The idleing problem.
The face of the piston.
The swollen gasket.
Also I forgot to mention that some of the bottom head bolts were covered in oil/grease. I don't know what this means.
Thanks Spencer
