It's stalling and idling very rough. WOT and <br />cruising speed are fine, but it fights us to <br />start and stalls after being in idle for a <br />couple seconds. Very annoying around docks and <br />when trailering.<br /><br />We just had the carbs rebuilt, everything <br />cleaned up and greased, plugs changed, new water <br />pump and impeller, etc, etc... and it's running <br />like crap.<br /><br />Of course it was running great at the service <br />place because they hook up their own fuel supply.<br /><br />So now I'm stuck having run it on the older fuel <br />about 10-12 times now. (he put OMC 2+4 <br />conditioner in and tested for water... said the <br />fuel was passable, but probably not perfect).<br /><br />We've since filled up and it's running even <br />rougher. The fuel that he conditioned and said <br />was okay was probably in the boat for 4-5 years <br />before we got the boat... so I'm sure the tank <br />is full of nasties I imagine.<br /><br />Question is, short of pulling the whole top off <br />and replacing/cleaning the fuel tank, what else <br />can be done? Or is that probably the best thing <br />to do in this situation?<br /><br />I'm going to check the fuel filters on the two <br />fuel pumps and the guy that serviced it <br />recommended checking the bowls of the carbs or <br />something to that effect for contamination. <br />Maybe run some of that Seafoam stuff through it <br />to clean the engine out?<br /><br />I'd bring it back to him, but he's in FL and I'm <br />in SC and he only serviced the motor... it ran <br />great when hooked up to his fresh fuel supply.
