ryanmfairbank 26 #1 Posted June 6, 2016 After recently acquiring a '77 Wheel Horse B-80, I had to give it some TLC... Fuel Delivery: new carb, rebuilt fuel pump, new fuel lines, new in-line fuel filter, installed an in-line fuel shutoff, cleaned the inside of the fuel tank and petcock... Start Circut: new battery, new solenoid, and all new wiring... so...it starts right up, and sounds great, but my problem is with the throttle...it seems to either be purring beautifully at idle, or ready for takeoff at full throttle! lol There is no in-between...what am I missing???
