Gumming
 

I have not ridden my bikes since October when I tore my knee up. I put a Stabil type additive in the gas tank and have started the bikes a few times.
Which will gum up faster ... carburetor or EFI?

Good question.

The owner of the marina where I launch has been having trouble with stabil/marine stabil and has better results with star-bright star tron this season.

Avgas...unless you have a catalytic converter.
That is all.

To answer the question...I would think a carb would be subject to gumming faster.

Any fuel with ethanol in it is having a tendency to phase out, separate, and cause some kind of gumming or sludging junk.

I don't think there is anything on the market to keep the two parts "in phase".

Tend to agree. Have had as good of luck using Sea Foam as anything.

I generally use seafoam as well. With the shovel, and other carb-equipped motors, it shut off the gas and let it run the bowl to empty. It isn't foolproof, but it only allows a little sludge to accumulate.

Posted under duress using now-buggy FREE Tapatalk I previously paid for.

Fabulous. That's what I used. I keep it in the saddlebag and add 1/2 oz. with each fillup.
