The gas welding wasn't progressing as well as I thought it might. The heat was taking its toll on the edge of the tubing and would cause extensive grinding to make it fit again. I stopped and broke out the MIG. I practiced for a while adjusting the voltage and wire feed. I finally got up the guts to attempt the short welds along the strap to the tubing. It worked out fine. I cleaned the welds and polished the inside of the tubing with emery cloth one final time before painting the exterior with a heavy gloss black rustoleum paint.

Then I discovered one final glitch. The cheapo air cleaners were designed to be fastened with set screws, bogus ones that were basically sheet metal screws. I jammed to the hardware store and bought a couple of Allen 10/32 set screws. I drilled the holes out and taped them to fit the set screw, then buried the screws in blue Loctite.

Just one final touch. The long 5/16-inch bolt that held the unit in place fit fine, but since it ran between two straps and a bracket to the top motor mount, with a large gap inbetween, it would flex if tightened too much. So I drilled the end of the bolt and installed a cotter key to prevent it from ever backing off.

I think that's it. Let me know what you think. --Bandit
