Hi guys hoping you can help guide me in the right direction new to the community so bare wit me, I just recently bought a procraft boat that needed some engine work done " Needs carb work" I was told, well after paying and getting it home and what not i ended up swapping out the engine harness doing a lower rebuild carb rebuild fuel pump rebuild and she was running like a champ but started making a noise like a belt was lose, I checked the belt was fine but while doing so i turned the fly wheel up top to save my self from hitting the ground "One leg left due to a IED" and well it turned on me and now will not fire up, any suggestion ive look in the manual but there are about 400 timing settings it seems like and i want to be sure i do it right. Like i said before it was running 5 minutes before i took the belt off and moved the fly wheel now it just turns over and wants to back fire almost.

Im going to get some pictures with the engine cow off and what not to maybe give a better idea of whats going on, and if anyone in the Augusta GA area knows anything ill pay ya gas money lol.

If I understand your post, you have removed the timing belt, and now want to make sure it is correct? Turn the flywheel until the timing mark on the timing pointer (black plastic arrow on mid seventies motors) or the timing mark (early 70s motors) on the cowling support indicates top dead center. Now look at the cast arrow on top of the distributor pulley. The arrow should point at the one or three dots on the flywheel to the right of the TDC mark. If not slip the belt off and turn the pulley until it does. A manual will help you check timing and synchronization.
