    Mercruiser 5.0/Chevy 305 firing every other cylinder

    Took off carb and cleaned every single port. I noticed that the new float needles were sticking a little in the new seats. I still have my old ones so I put my old ones on and they did not stick like the new ones. Anyways I put it back on the engine and were golden. Got myself a V8 now instead...

    Mercruiser 5.0/Chevy 305 firing every other cylinder

    Pulled plugs on one side(Would have done all but its a challenge to get the out without removing the exhaust), anyways the firing plugs are very similar to those suspected of not firing but those that are not firing are dry compared to those that are. Dont look burnt just dry.

    Mercruiser 5.0/Chevy 305 firing every other cylinder

    So I've just redid the whole interior of the boat and decided to tackle the engine. It was running okay just was hard to start. Anyways here's what I've done as a background. To address the hard staring issue I've rebuilt the carb, set ignition timing, and checked plugs/wires. I have also...

    5.7 /Chevy 350 hard starting and stalling when idle

    I just had someone offer me an engine, the 5.0 is fine, but since I'm overhauling the whole boat this winter/spring I wanted to see if it'd be worth pulling the 305 out and dropping the 350 in or just keep it as is.

    So I've got the option to get a deal on a Chevy 350. Would it be worth swapping out the 305 for a 350?

    Thanks yall, I am going to start with checking timing then gonna pull carb and rebuild it since I do not know the history of it. Any thoughts of going Holly EFI for ease of use.

    5.7 /Chevy 350 hard starting and stalling when idle

    5.7 /Chevy 350 hard starting and stalling when idle

    I've got a boat that someone put a 5.7 in and I've been trying to chase down an issue with it not starting right and occasionally dying when idling and then being hard to start. The engine has an Edlebrock carburetor with electric choke on it. I've read these have an issue with fuel being...
