I have sourced a 9794234 intake and a 7029268 qjet carb. 1. The intake is dusty/slight rusty inside does it need to be "tanked" or just blown out? 2. Does the cam need to be replaced to support the above intake and carb? 3. What is a good source for qject carb rebuild kits and parts( it is missing the choke pull off to secondaries link).
