that information is crucial to problem solving an engine, especially a freshly rebuilt one thats under preforming. heres a kit from HF for $35, I have a similar one...its good enough for this. another on amazon for $15 problem solving from a different angle--did you do anything to break in the new engine? Engines dont usually have full power right after assembly, so maybe you just haven't gotten your's broken in after the rebuild?
