carb question from a newbie - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The lockup solenoid is inside the tranny. This locks the tranny in overdrive. If it sort of acts like you are letting the clutch out, like in a manual, when put in gear, this could very well be the cause.

You can buy a tool to fit the mixture screw heads. Someone on here bought some from I think Pepboys. I can't remember what they are called though. You more than likely will have to remove the hardened plugs covering the screws first.

I made a tool to fit mine. I used a piece of steel tubing, I think it was 1/4" or so. I bent the two opposing sides flat. Works great.

Hey, us Mikes are good people.
