Modified genuine Walbro WYK33 Carburetor is $185.00 These are discontinued by Walbro but we still have a few left. We now use the China version of the WYK33 which has an aluminum barrel and is already bored out to start with. It does not have a radius entry. After we modifiy them they work just as good, if not better, than the original Walbro carburetor. The modified China version is available from us for $81 and it comes with a billet throttle arm.
This is a highly modified version of the Walbro WYK33 carburetor. It has had the body and the carburetor barrel bored bigger. It has a step machined into the body and then a radius entry epoxied into it. These changes increase the airflow by 33%. This carburetor now uses a remote pulse line, but the pulse line must be a special hard hose and no 90 degree fittings allowed. All current Quickdraw engines now come pre-drilled and tapped for a pulse line. These carburetors are tricky to modify. In the photograph, there is a WT257 shown on the right for comparison only to WYK33 which is on the left.
