Believe it or not, this is the Part Number for the Complete Carburetor! It is a Compliation of individual part numbers and very seldom are they ever all correct!

Sometimes it can mean spending $4500.00 in cores just to get all the right stuff and now days good cores are harder to find than an Honest President!
