This is a first for me, but when adjusting the float level on the secondaries, fuel squirts out from from the adjustment nuts. Never happened before, but I just replaced the needle and seat. Fuel levels are low in bowls and can’t seem to adjust it. Wonder if floats are stuck inside? Or is...

I want to put a Keystone clamp on the rubber fuel line (3/8") going into my 440 fuel pump. From Jegs I ordered their 3/8 keystone clamps figuring these would be correct, and they're not (too small). Using my calipers, I measured the thickness of the fuel line on the fuel pump and it looks...

My '69 Super Bee was originally a 383 4bbl car, but I bought it equipped with a Six Pack setup. Would it make a difference if the Six Pack setup still has the 383 4bbl throttle cable on it? Would it just be a matter of pedal position? Or as long as the throttle plates are opening fully, the...

I'm trying to help my buddy tune his 70 Road Runner with a 440, iron heads, 4spd car. He's got an Edelbrock Thunder Series 850 carb on the car. The car drives nice but when he gets on it in 2nd and 3d gear, it starts misfiring. The carb is still setup as it came OOB. He doesn't want to dump...

So I need some tuning parts for a 1969 Carter AVS 4615 (4bbl carb used on 383 engines). Does anyone know what Edelbrock parts are interchangeable with the Carter? Specifically looking for the metering rods, springs, etc. TIA!
