I'm writing for an owner of a new-to-the-area-KR2. He has a Hapi 1835 on his relatively plans-built KR2. Static engine runs are showing only 2400 RPM with a Props Inc. 54 x 47 prop. I'm thinking it is over-pitched.
So far Fred has: * done a compression check and found all in the mid 70's * verified the timing is correctly set * they are replacing the intake filter and replacing the suspect carb. I've encouraged pulling the twin 2 into 1 exhausts to inspect for any possible blockage. Besides a possible (probable?) bad tach, what other areas should Fred and his A&P be looking for that might cause this issue? Thanks and I'll forward your replies to email-less Fred!
