I converted a Ryobi with bowman ring rexcel ignition and have run 10 litres through it.
Compared to my other Ryobi this one has failed to develope compression.
How long should it take to bed the ring in, it doesn't seem to be getting any better.
I used some emery on the cylinder with a light "hone" to help but it is not even close to what it should be.
Any ideas.
