We bought a short block for mower put the heads on it I tried cam both ways because it wouldn't crank so I thought it was out of time so I took motor out open it up timed it by the marks but I'm blowing out of intake and sucking out of exhaust what's wrong? I've been a mechanic for 30 years and have done all my small engine repair but I'm confused please help
