Mill Off 38/38 Choke Good Or Bad?


Recommended Posts

Chump car/ 24 hours of lemons, webber 38/38. Looking for the extra few HP to keep up with sister 2.2L tii. Is milling off the choke assy a good or bad idea for increasing air flow? I know its a super common thing for the racing holley 4 barrel guys, i just wanted some input before i do something there is no going back on. Almost all of our races are warm weather, and i figure cold weather we would warm up in the pits with manual choke ie. hand over carb if needed.

Data point: I've seen fellow racers who've milled the top off their 2x38 carbs, but have not noticed them going any faster.


(Now, if you'll forgive the unsolicited information which doesn't directly answer your question....)

Proper jetting for the atmospheric conditions (corrected altitude) of race makes a noticeable difference. Of course, the driver and tires will be a major part of keeping up with the Tii - good luck. -KB
