Is there a consensus as to which plug works best with the Ryobie gassers? I have a newer single ring one. Can't remember how you tell if it's a 26CCr33CC Something about exhaust port opening.
I have a box of NGK-BPMR64A's. Will be firing plug with CH CDI unit.
Will they work or do I need to purchase different one?

BTY: Thanks for the help on carb venturi sizing.

I've swapped the NGK BPMR6F and the NGK BPMR6A back and forth and couldn't tell any difference in the way it ran at idle or the max rpm it turned.

most ryobi engines are 31cc, some of the older ones were 28cc I think but they didn't make them for long...

I bought my "31" in 1985 as a Lawn Boy. I used it for 14 years as a weed whacker before I converted it. I have a newer 1999 one that I use as a whacker now.

Is it okay to use a plug that has a gasket ring on it in my Ryobi head that has a tapered seat?
I have been running an NGK-BPMR6A,seems to work fine.

I've played around with my Mac, Homelite, and Ryobi engines and swapped back and forth with the gasket and tapered seat plugs in them and it just doesn't make any difference in the the way the engine runs as long as you stay in the same heat range.
