307 2Jet Float Settings - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone have the float settings for a GM 2Jet Carb on a 307?

I believe it's float level at 27/32" and drop at 1.75"

Thanks, Dave

I know this isn't what you are looking for but I just pulled mine apart because it was dumping gas and the idle mixture screws could be bottomed out and it would still run fine.

I cleaned it out and adjusted the float so when the top half of the carb was upside down it was roughly level.

Runs excellent and the idle mixture screws work again.
