Is it possible? Has anyone tried this?
Just read an artical at
www.massbia.com/articals/sludgetrap.htm that says the sludge trap can be cleaned without tearing down the motor by removing the top end, removing one of the fly wheel bolts, and timing cover, using solvents (carb cleaner). I have never been into one of these engines but it seems possible to me if the sludge trap is not to restricted.
