Thermoquad vs square bore

thermo quads run fine when the secondary air door is set properly,,,and its not hard to do,,,,most people dont like them because they no nothing about a carb and how the therm quad works,,,i didnt know any one had rebuilts,,intresting i ran one years ago on a 340 and a 400 in a road runner,,, good mileage also when just cruising,,, small primarys,,,just my opinion
