Chainsaw Repair

The other thing that crossed my mind about transition fuel delivery is the 'idle' holes which are drilled into the throat of the carb below the welsh plug.  Usually there are 3.  The 1st one should be visible from the throat with the plate closed looking into the throttle bore.  #2 is directly beneath the plate, at the cutout, with the plate closed.  #3 is on the venturi side of the plate. 

Im trying to post the drawings for the 268, the hole sizes are in the narrative.  I dont know how much larger I would go with those holes unless you want to start running alcohol instead of gas.
