I just put in a 350 crate motor. I am having trouble getting it timed correctly. The sticker say 4 degrees but I an't get it to run there. It spits fuel out the carb if I even get close. It runs pretty wel if it is about 30 degrees before tdc (just a guess). If I get anywhere near 4 degrees, it fails to run. What can this be? I am pretty sure the dist is in right. How well will it run if I put tdc on the exh stroke? Pretty sure I did it right but that would be an easy fix so I am hoping Everything is new. Distributor is rebuilt with a kit. I replaced everything except the mech weights since they did not seem to fit right... Any ideas why it won't run close to 4 degrees? .
