How do you test a VOES switch on a Harley Davidson?
It is a simple on off vacuum switch that switches at a specific vacuum. Takes a vacuum source like a MightyVac pump and then your multimeter to check voltage. Watch voltage and then apply vacuum and note the vacuum level when the voltage changes. If that works, then the VOES is fine.
What is VOES on Harley Davidson?
These letters stand for Vacuum Operated Electric Switch. It senses vacuum behind the butterfly of the carburetor and advances or retards the ignition timing accordingly. The Harley VOES switch remains closed until vacuum is introduced.
How do you adjust the VOES on a Harley Davidson?
To adjust the VOES to switch at a higher vacuum, turn the adjuster screw 1/4 turn clockwise. Now repeat the test from above to see where (in inches of mercury) the new switch point occurs. If you want it to switch at a lower vacuum level, turn the adjuster screw 1/4 turn counter-clockwise.
Is the Dyna Wide Glide a carb cough?
After buying a 2000 Dyna Wide Glide a year ago for half price from an unemployed friend who was moving in a hurry, I started to work on the low speed (and dangerous) carb cough. You know, one of those that gets you while low-speed turning. It idled pretty good, and ran cheetah strong, with some backfiring.
What makes the carburetor pop on a Harley Davidson?
One of the most common problems that customers complain about is the spit-cough-pop from the carburetor as a Harley goes from idle to ¼ throttle. This can occur on any model, any carburetor, but seems to happen most often with the stock CV Keihin carburetors used on the newer (90 up) Big Twins and Sportster models.
Why does my Yamaha Grizzly Pop through the CARB?
It doesn’t do after I am going faster, only about 10 mph and under. It also does it sometimes when I let off the throttle. It seems to do it worse when its cold. When it does it shoots fire back through the carb. Does anyone know what could be wrong?
Why does my carburetor make a popping noise?
Popping noises from a carburetor indicate a form of backfire. Too much air and not enough fuel causes backfires to occur in the intake manifold. The exploding mixture then vents through the carburetor.

Why does my Eddy 1406 carb keep popping?
I’ve checked the timing and that’s fine, I’ve even swapped carbs (from an Eddy 1406 to a Holley 3310-3), but the popping persists. So I’ve come to the conclusion that this must either be a compression issue or a cam issue, or something else I’m just not thinking of.
