Hey folks, A buddy dropped his 435 off on my bench for a carb rebuild, and after the rebuild it idles erratically. Sounds like an engine missing a cylinder. I've vac checked fuel lines, pulled the carb (Zama) to make sure the impulse was clear, ordered and installed a whole new carb(OEM), and put in a new plug. Fuel filter is fine. And when I try to accelerate, it spits and sputters and never gets above where the high idle setting is. Any ideas?
