I need some help with a Ryobi conversion to improve compression.
I have been using these for years but I am having trouble with a motor that lost power and performance.
I have tried a new cylinder and bowman ring but it doesn't develop that snap and when hot seems to have none at all.
I have been using a synthetic oil and thought about going back to castrol 2t mineral for a better seal and breaking in.
I used to get 7600 on the ground with a master 18 x 8 but 7300 is about it now.
I gave the barrel a light scrub with wet and dry hoping it would bed the ring in but no joy.
Any ideas or tricks on how to improve this rebuild would be appreciated..
