Is Corky's Cub Cold-Natured, or What??

[Donny M]

it was 17 at my place, an i have got to go fly this morning. it is just to cold out there

Just think of the extra lift you'll have this morning

Corky, I too think it's a fuel flow issue, using the choke draws more fuel into the system. Check the complete fuel system from the main jet back to the tank.
One of my tractors had a simular problem it turned out to be crud in the inlet to the fuel strainer. Used a little compressed air (short bursts) in the end of the fuel line. I did this while holding a rag over the filler.

Charles:


I also think it is a fuel flow issue... go through it. probably a little dirt from the tank.

It is -3 C here this morning, we have a heavy winter storm warning, already a foot of snow on the ground and another foot expected -- first one of the seasson. Ellie still is missing her head.. but at least she is indoors..

Ifn you guys wanna get some seat time and plow some snow.. come on up

Well, since you've added the factor that it runs better with choke then I'd have to agree that it sounds like a fuel supply issue.

[Dale Shaw]

Just bring it up here Corky, it is warmer and will run better. I will trade ya this one, it is running good.

Sorry I didn't mean to Jinx you Geoooorga guys. So ole Jack frost is making house calls in the south east. Never would have thunk it.
Yes that pull the choke trick really means it is most likely the jet.

Topic on radio program was Florida boaters having problems with ethanol blended fuel. From the topic, ethanol absorbs water vapor when stored in vented fuel tanks. After a while the water/ethanol mix drops to the bottom of the tank causing problems. Below is a comment from a pro ethanol board.

Q: Will ethanol-blended fuel attract moisture to my fuel system?
A: All of today’s automotive fuel systems are closed systems and are less prone to attracting moisture. Ethanol absorbs moisture that is in a fuel system and carries it out in suspension as it is consumed. The most likely, and quite rare, cause for water in gasoline today would be from condensation in service station storage tanks. If the concentration of water in ethanol becomes excessive, it will separate and fall to the bottom of the fuel tank. When ethanol fuel is used in winter months, a fuel de-icer is not required.
