Re: Old engine question

Mark, as a C/L flyer therfore a user of older engines, I would not
reccommend cleaning or replacing the piston/sleeve unless the
compression is very low. In older engines the varnish helps to improve
the piston/sleeve seal. Cook the rest of the parts.

I have an old O.S. Max .20 FP engine that has set up for probably 10 years
or more in a non temperature controlled storage shed. I have finally got the
thing disassembled and there is a load of varnish build up all over the
place. I am thinking of replacing the piston and sleeve, but as I said all
the other parts have varnish build up on them and I thought of soaking in
some sort of solvent to remove it. My question is what type of solvent
should I use to do this.

Also, might anyone out there have the original instructions for this engine?
