So while its great fun running around in our rebuilt wellcraft, the carby is giving us grief. its a holley 650, but a model only made for a couple of years, so the right rebuild kit consists of bits from 3 kits (info from holley); to simplify the question - can i buy a slighty used 650 from ebay (off a similar sized car engine) and bolt on and go? what sort of tuning would be needed...

NO


You need a marine carb or BOOM

post your carb number up. guaranteed there is a carb kit for it. BTW, its usually cheaper to buy bowl and metering plate gaskets, base gasket and power valve by themselves than it is to buy a kit.

Lol, so is that a maybe?

"Car carbs are vented to the outside,...

Is it just the 'j' pipes that vent to the manifold?

carb is stamped r84037 2601 - the main bugbear is the top of this carb is 1 piece including the tops of the float bowls

this is the response from holley: "Kit # is 37-1541, Floats are Sales # 116-3. Power valves will be different. If customer needs specific power valves. He will need Sales # 125-85 bought separately."
