more info needed

"i need to take it in?"

Get a factory service manual, a decent set of tools, some patience/willing to learn, and no YOU can do it. :)

Re: help

athenb, welcome to iboats.

Start with the basics, check compression, and spark on all cylinders. have you tried choking it when it starts to die. when were the carbs last cleaned and rebuilt?

Re: help

Agree with TD. Check your fuel filter as well. You didn't mention if it will run at higher RPM's. How old is the fuel you are running?
