hi i just got a st15 in a trade and got the enging to fire but only when the throttle is wide open then within a few seconds it cuts out im pretty sure its because the fuel isnt getting to the engine any ideas of why? and how i could fix this thanks. jon

Have to get the carb clean and make sure the adjustments are where they should be.

i feel so dumb but i just richened the hsn and the lsn and she fired right up and did very well thanks for the advice though
