Cold Weather Running By alleyoop (Read 491 times)

It has been cold around here and my trike is in the garage and it is an attached garage not heated but it is not freezing in there.

Well I just went out and started it to get things moving through it like I always do about once a week and let it warm up for about 15 minutes or so.

It cranked right up pulling up the Enricher(MANUAL) choke I have on it and as it warmns I start to close off the Enricher.
Well it was running rather ragged missing and wanting to die without giving it a little throttle. But I noticed even giving it a little throttle it was missing. I took the access panel off and brought up the idle and that did not help Which I knew it wouldn't because that is as if your twisting the throttle. But I wanted it to idle higher to check the Fuel Ratio.

I got my screwdriver and As I turned it Counter Clockwise the RPMS started to rise I turned it out about 2 full turns and the motor jumped up to 2000 rpms and running smooth as silk. I then turned down the Idle back to around 1500-1600 rpms.

So in case your scoot starts to run ragged and missing and wanted to die it could be due to outside temp changes and it is running to LEAN when the Temps Drop.

Now the opposite could also happen when the Temp changes from Cold to Warm, In this case it may be running to RICH.

Alley,
I am in Connecticut and its cold here also. I put my bike up for the winter and the most important thing I do is to drain all of the gas from the tank, lines and carb. Gas is formulated with ethnahol(sp) which quickly deteriorates and leaves a sticky residue on everything including carb jets. What you are seeing might be a residue on the jet and its seat that is closing the effective jet size and causing a lean run. Opening up the jet (turning it counterclockwisw) will increase the opening and will allow the engine to run richer.

Even tho you run it each week consider adding a fuel stablizer to the gas to help eliminate the problem.
