RE: gp pt-19 and os 91 fx muffler problem
I measure 15/16" from the centerline of the head to the face of the muffler mounting flange on the side of the head. This gives us 1-13/16" of clearance. I'm still looking for a U.S. distributor for BCM.
Jim @ Bisson said the dimension we're looking for is 1-1/4". This will work! I have e-mailed Brison & Tower (distributors) for availability and price. Will keep you posted.
