RE: another darn ryobi post (ryobi performance modification, analysis and comparison)
I had the same problem with an XYZ ignition on my Ryobi. I switched to RCeXl. Both are the same price at southeastrcengines.com
I had my XYZ ignition screwed down to a plywood plate and the bottome cover broke off from the vibration.
Buying from southeastrcengines.com gives you a warranty in the US. I prefer the easier starting on my Ryobi.
