[cant move arm freely up and down] should be .015 clearance at WOT [ENGINE OFF PLEASE] ONLY!..simply so you are NOT BOTTOMING OUT ACCEL PUMP!... forget springs etc in secondary..THIS IS A PRIMARY PROBLEM... might pull pri bowl to make sure there is no flakes in it as they will clog jets OBV.. keep us posted..
