It seems my carb is not squirting when throttle is fwacked. In the past I've had to replace a little brass thingy (approx 3/8" long X 1/8" dia needle) like a check valve. Is there any other way? I hate taking the carb off to change this out? If it gets stuck, any way to dislodge with a forced brake clean spray or airgun? I would think a SS ball would work better, & if it needs the weight, maybe 2-3 balls would work. Anyone else have experiance in this area. Thanks ahead of time.
