you have two problems. 1 there is too much fuel in the carb. if you ran the carb then let it set for any long period of time; the gaskets will go bad. if its new, then check the float level. next, check the timing with #1 plug out and the coil wire is disconnected. turn the engine over with your finger in the [#1 plug hole] until you get compression. stop and look at the position on the distributor set to the #1 point. the retard it a couple of degrees tighten the dist nut. then you can try starting also make sure the plug wires are in the correct position.
