Slight skip in 37 six

Posted by CORSASEVEN On 2016/7/3 22:17:08

I have replaced the engine in my 37 including all new tune up parts and plugs. When I start out in 1st gear and at the beginning of 2nd gear I feel a very slight skip . I replaced the plugs temporarily with another new set just to see if I possibly acquired a faulty plug but no difference. Compression is excellent. Engine only has 120 miles since the rebuild. Any suggestions where to go next? Thank you.
