tell me what kind of carburetor should I buy

Are you looking to buy new Dave? With a manual choke, the Mdl 4779 is still a good regulation performance DP carb. Being in Canada, if you want a electric choke, you'll have to go with the Ultra series. Neither one is cheap new though.

I was looking to buy new.I really have no idea so I thought I would run it by the members. I would like to be able to get away for no more than $600 .
