Thanks, paper gasket material it is then.

Hey, here's a question for you and DougT...

The lore surrounding four stroke vs two stroke glow engines is that a 1.5:1 factor is needed to compare them. Thus a 0.70cid four stroke is deemed equivalent to a 0.46cid two stroke, and 0.90 vs 0.60, and 1.20 vs 0.90, etc.

Does that mean the Ryobi 26cc four stroke is only going to measure up to about an 18cc two stroke? Or are the rules different for gas vs glow?
