I had to replace the Cylinder in my CRRC26i as the small end bearing failed and fragments scored the cylinder wall. I cant get the engine to run after replacing the cylinder. The compression feels very low. My electric starter will spin the engine up quite fast and I can hear it firing, it sounds almost like its idling but stops as soon as I take the starter off. Anyone know what might be wrong?

get a frank bowman ring. You need to get that compression back up.

Agreed. A new ring might be in order.

Love your country by the way. We haven't been to Limerick yet, but hopefully one day.

Looks like it's about 10C there now. I'll gladly trade you for our -10C, 55KPH winds, and snow.

I replaced the piston ring, ran it on the ground for 3 hrs and it seemed fine.Then it started getting harder to start, first it would fire but would not stay running unless it was started at about 1/2 throttle, now it wont run at all,fires up sometimes and quits after about 2 secs.With the carb off I can hear a little air getting past the piston ring during compression, is this normal or should the ring seal completely? The compression seems fine.

New NGK plug, not Chinese? I have a small collection of Chinese spark plugs that are junk. Why 3 hours on the ground? They break in much better in the air. Good luck. Wait, you've already got the "luck of the Irish"!

Thanks, tried a different plug and its running fine.its another Chinese plug, I don't have anything else.I have not had a problem with the Chinese plugs before although I know alot of people do.I'll get NGK plugs in future.
