Re: Elto Ace 1.8 low compression

[wedgie]

quote djeady:

I’m still trying to get my old Eaton Viking/Elto Ace running. The spark and fuel are good, I just don’t seem to be getting any compression.

I’ve put in new rings (couldn’t see any difference between old and new) honed the cylinder, and used gasket sealer on both sides of the gasket. Cylinder looks fine, piston looks fine. Used a brand-new compression tester as my old one was suspect. I get compression of less than 20 dry and about 25 wet. I think it should be about twice this. Any ideas where to look next?

Looks can be deceiving. If the cylinder is too worn, new rings wont be enough. You can get an idea of how worn the cylinder is by measuring the gap of the new rings when they are inserted (without the piston) in to the cylinder. I don’t know what the gap should be, but hopefully someone here will have that info.
