Not a everyday Hotrodder question...
Me and 5 of my friends decided to buy a boat as an summer project (Yes it was a big mistake lol), but now we have everything done, new plugs, electrical, lines ect...So for the first time we take it on the water, and we rev to about 1500 RPMS it starts to shake and past a certain point it'll backfire and pop and refuse to rev higher. Any ideas? Thought it might be from the Carb being too lean? Or fuel pressure? Its a 2.5L I4 Chevy with a 1BBL..Thanks! It also has a hard time turning over right after, we have to wait an hour or so for it to be able to turn over.The revs it was able to obtain got worse and worse
