Seafoam is a cleaner for the fuel system and oiling system. How old is that DUI? Do you have a tach connected? If so, is it steady or any needle jumping, flickering?

Seafoam helps stabilize ethanol gas and can clean out deposits in the fuel system.I’m not familiar with what Seafoam does, but will try it if you think it would help.
DUI is of unknown age. I have had this 40 for 6 years and it was on the blown engine that came in the 40. A replacement 2F engine came with the purchase and we transferred the DUI over to that replacement motor. My guess is that the DUI is probably 8-10 years old. I don’t have a Tach connected so can’t answer those questions.Seafoam is a cleaner for the fuel system and oiling system. How old is that DUI? Do you have a tach connected?

Thanks, will give it a try to see if it helps.It's a cleaner for your fuel system. I have john deere mower that was missing at idle. I took out the carb and dipped in carb cleaner put it back together and it still an issue idle. I should have poured seafoam in the tank instead. Seafoam fixed my idling issue. I have several experiences where seafoam came to rescue. It may or not help but if you never done this it's worth trying, not going to hurt it.
Thanks, I’m going to try it out.Seafoam helps stabilize ethanol gas and can clean out deposits in the fuel system.
I prefer it.
Thank you, I really appreciate your advice. I am currently reading through a bunch of your other carb advice threads and watching your YouTube series on rebuilding the carb. I may find the courage to try a rebuild.If the fuel level rises, then the inlet needle valve may be leaking.
It is possible that the engine is flooded when you try to restart the engine. Carbs are notorious for having problems with "reformulated" gasoline causing them to leak fuel into the intake manifold and flooding the engine.
To test this possibility, do the flooded start routine:
Push the choke all the way in (open). Hold the gas pedal to the floor and do not pump it. Crank the engine and then let off on the pedal if / when it starts.
