Reply To: Elto Cub Compression

Boat House,

I disassembled the cylinder today.  Using the top (existing) compression ring, the ring gap is 0.008″ at the bottom of the cylinder bore and 0.030″ at the top.  I don’t know how much of this is attributable to ring wear and how much is cylinder wear.  I’m willing to spend $11 on two new compression rings and see where this gets me.  I get only about 25 psi now on a compression check.  From this forum, it looks like I’d need 50-60 psi to have a chance on this engine running.

We’ll see where this goes.  If compression comes up with new rings, I’ll tackle the ignition system.  Otherwise, this motor is a wall display.

Thanks for the advice.
