What is the diameter of the intake stub on a Poulan 46? Why not take a 90 degree high temp tubing (silicone rubber) and make a manifold to put carb in better position. It would be easy to make a aluminum flange that carb bolts on. The flange would be welded to a simple piece of aluminum tubing the right dia that pluged into rubber manufiold at carb end. Pluse line could be attached to a nipple at each end. just a idea. If I had a 46...I would try it. Capt,n
