"I just bought a 78 carver with 302's.
I replaced the port side engine with a long block. The boat sat for years before i purchased it.
The problem I am having is I start the engines ok. And they run ok untill warm up , then when I put on the gas I don't have much power, and I see light smoke with a gasy smell to the exhaust. when I bring it back to idle it stalls, and restarting is very tough and it won't hold idle. just stalls. I can keep it running above 2000rpm. but no control. Help me please. My mind is fried."

"Rebuild carbs/ change fuel filters (and maybe pump out tanks)/ clean water separators if equipted (and add if not).

THe spark advance might be rusted stuck as well. You can check that out with a timing light. THe advance should be all in at 3,000 rpms.
