am i understading this correct? run the engine with THROTTLE FULLY OPEN FOR 1 MINUTE in rich setting right after starting???
thanks for the replies and tips in advance...
Yes. With an ABC or ABN type motor you are making the piston and liner break-in to one another. Hence if you ever have to replace either the piston or liner, you replace both as a set.
With a ringed motor the break-in is totally different, much lower rpms till the ring seats itself to the liner. Then ya let her rip!
