Re: Old engine question



There was a great article two months ago by Dave Gierke in Model Airplane
News on the topic of de-varnishing an engine. Try to get your hands on that
issue.

A letter to the editor following Dave's article suggests a product called
"Dawn Power Dissolver" sold in most grocery stores for removing burned on
grease. I've tried it on external varnish and works great too. But read
Dave's article.

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?
