Looks like some bad (watered down) gas made it's way into my tank. Obviously no fuel water separator or this conversation wouldn't be happening. Pulled the main tank, drained/cleaned it. The question is can the water
already in the carbs be removed somehow? Dropping the bowl and dumping it worked on the lawnmower. Maybe a drain petcock exist? Will the water eventually run thru to motor? Trying to avoid carb teardown if possible. Will be adding fuel water filter/separator now for sure!

A lot of the carbs have a bras hex bolt at the base of the carb bowl. These allow access to the main jet, but can be used to drain the carbs as well. Remove the bolt and pump the primer until you see fresh fuel emerge.
