Ok, at wits end here. After a lot of other issues thought I had my engine in a reliable posture. Not so much. Starts great at the dock, runs great for about an hour then will start a slight miss, that progresses. Taking it out of gear engine revs well, back in gear misses and ultimately dies. Wait 15 minutes, starts right up, runs great for 15-20 minutes then dies again. Wait and will restart, then the process repeats itself.
Brand new carb installed last week, new fuel line, electric fuel pump. new fuel filter, new fuel/water filter, fresh gas. Tried taking the fuel cap off to see if maybe it was a venting/fuel lock situation, no difference. I am virtually certain it is a fuel starvation issue, so maybe gunk in the tank that settles to the bottom when at the dock that gets stirred up while moving and clogs the fuel pickup strainer? After releasing the vacuum after is stalls out and by letting it sit maybe the gunk goes back into suspension in the fuel, lets the engine start and run great but clogs back up more quickly the second time because the gunk is now agitated into the fuel so it clogs the fuel pickup more quickly?
Getting exasperated here. Engine dying while trying to put the boat in the slip stern to is not any fun, not to mention the unreliable aspect of having an engine when needed for as long as needed. Ideas?
Thanks.
