[QUOTE="CarlHungness, post: 173898, member: 2517"] Your reply makes me feel a little thick. In order to put an adaptor Don't think I've ever had over 90 in 30 years. There is virtually NO leakdown. And my problem MAY have been my installation of the ATD 3 times...not setting it hard enough..will know tomorrow. Rings, pistons top end are all virtually new, less than 5,000 miles and it SURE feels like it has great compression. You cannot get it over TDC by standing on the lever, absolutely have to pull the decomp. I only weigh 160 but it'll hold me just fine and no easy trick to kick it with no decomp and just over TDC...feels like it has for decades, but I can't get over 90 out of it by kicking. [/QUOTE]
