Re: Glass Holley Sight Plugs?
The Holley that's on my 57 Chevy truck, I set the floats 9 years ago when I built the carb. Never adjusted them again, never had the brass sight plugs out.
I don't screw around with it and it doesn't screw around with me.
Ever notice that guys don't constantly screw around with the floats on Q-jets, Carters, Edelbrocks, Webers, etc, etc? If the floats on those carbs were externally adjustable guys would be screwing around with them all the time, installing glass sight plugs, getting into debates on technique, frequency of adjustment, minute differences of fuel pressure and its' effects, etc, etc. The float/needle&seat assembly is not substantially different on the externally adjustable Holleys than those other carbs. Set it, forget about it.
Heresy, I know.
Know what else? I've never owned or spent even one dime of my money on one of those MSD red brick things you see on so many firewalls. Never will. Guess I must be just a total hot rod failure......
I think I'll change the air in my tires this weekend. Get some overpriced double throwdown super trick air and install it.
