Thermoquad mods that work.
@Bewy I have a few TQ’s I have cut up and ground on in an effort to seek information on not published as well as to find limitations on grinding away at various parts of the air horn. Experimentation came to a stop at a point. Other more pressing things in life take precedence of course. I’m looking forward to my garage being built for many automotive reasons. The process is painfully slow when you want it done yesterday.
Have you taken to drilling out the fuel passages in the air horn (top section) from where the fuel enters from the fuel line to the needle and seats?
(Picture below for reference)
I was asked about this a few times. I haven’t add it there yet. I don’t know what the inner diameter is and how far it can be enlarged. Once I knock out the plugged ends, I can figure it out. I also figure a set screw would work in place of the pressed in plugs.
I myself haven’t approached a limitation on the carb, so, this mod may not be of any actual benefit since the needle and west control the fuel afterwards. But a generous amount of fuel available there would insure a good continued supply to the needle and seat. It would take a good deal of consumption IMO to need a larger supply to the needle and seat. Probably out stripping the actual feeding capabilities of the needle and seat to need a larger fuel supply.
