<<can you show a picture of this please?>>

This isn't a 4053 - it's a 3810, but uses the same accelerator pump arm adjusting screw setup with the T-nut as used on the 4053.

All these pics and information is just fantastic. First chance I get I gotta pull the SR carb and compare the differences. I'm curious about the base plate differences.

Good pics John - thanks I know what to look for now, the other thing is the accel. pump cover half or more of the 4053's I see have regular phillips screws and not the clutch head type. is it confirmed all had clutch head originally?

FWIW, and JMO but Personally I have never seen a "Known Original" Holley 4053, 4346,  2818, 3246, 3247 etc., pre 1972 Holley carb that did not have the clutch head housing and screws. The later hsg with the Phillips screws shows up a lot on service dated or "restored" carbs from well known carb restoration company's for some reason. The early accelerator pump housings are very prone to bending/warping from over tightening as well as engine heat.

BTW I have been rebuilding/restoring carbs for 45 yrs., so I have seen lots.
