Another Carburator Success Story. (Clogged Scavenger Tube)
Just wanted to post a note of my joy in fixing my late model 4 bolt carburator.
The symptons: The Atomic 4 Engine was would run at high speed then stall and then not start. I noticed lots of gas sheen on the water exhaust too. The fuel problem started right after I left fuel tank get below 1 gallon.
Initially replaced oil water separator, secondary fuel filter, cleaned fuel sediment bowl and spark plugs which did not help. I looked at many suggested solution options on this forum. I even checked the hot water exhaust tube.
The Solution: Took apart the carburator and upon inspection notice the 1//8 dimater scavenger tube which connects the carburator to the intake manifold was clogged. After cleaning the tube, the motor started right up and has run well.
