Okay guys here's a tough question. My fuel screws are seized in carbs 1 & 2. The cylinders only fire when I blow through the fuel vent hose which forces fuel into the idle circuit. I adjusted 1&2 carbs vacuum to pull harder, hence pulling more fuel. Now all cylinders are firing but I can't seem to get the bike to idle less than 1500 rpm. This is a temp fix until I can find someone to sell me some carb bodies. My main concern is that I don't damage the engine with this improvised fix. Has anyone else tried this un-sync theory to get all cylinders to fire? :confused2:
