mercruiser alpha one gen 2 won't start

[steve3211]

2003 reinell with a 4.3L alpha one gen 2 mercruiser turns over fine but won't start. Put a little gas in carb and it fires but will not continue to run. I started boat over winter a couple of times and also added some fuel stabilizer. Currently close to quarter tank. Any ideas would be appreciated.

your carb could be gummed up, can you strip it?

thanks jack. Do you mean take the carb off and clean it? I probably can

yes get a clean large piece of cloth or paper , and carefully strip the thing, laying parts out on it , take pics of it if you want
if you have air blow it out, sight up the jets, be careful not to ream them but a wire off a wire brush is often handy
petrol(gas) engines dont like being laid up

yeah I can probably rebiuld it. Have you used sea foam or any other carb cleaner with any success.
