Okay, no hash marks on the choke dial, so when I get the idle speed/mixture/timeing vetted out, I'll hash it with a sharpie and try clocking it in.
For now....a view from the drivers seat....small dash mounted tach shows the same speeds on the dial as my Tach/Dwell/RPM meter so they are either both right or both exactly the same out of calibration. I vote to believe option one.
The ugly wingnut gets replaced tonight too....starten to get a Mr. Gasket addiction...oh no! Mister gasket pic later on. For now, admire the uglyness of the about to go in the parts box wingnut.
On advice of Counsel, and good advice too, the plastic fantastic fuel filter is gone...to be replaced by a nice shiney metal filter for a big V8 Dodge. Dodge V8 filter on a Chevy I6, thats funny there, I don't care if you have a mental disorder and like MOPAR. Oh yeah, almost forgot, nice nut!
As recommended, old cartridge cases and a small smasher wacker do in fact make great gasket punches. In this case, a beater fired 3006 cuts perfect holes for carb mounting bolts on my homemade spare gaskets.
