Recommended starting point for jetting on Thermoquad

It looks just like a model I reworked recently, #9150, had that odd vent/crap at the rear. I had to block off a few passages etc, but other than that it should work as well as any other TQ. What is the # stamped on the mounting foot?

I would check/do two things before installing it:
- check the sec high speed air bleeds & enlarge if not already 0.039-0.040"
- enlarge the sec jets to 0.143".

Depending on cam duration, IFR may need enlarging & more bypass air. Do NOT drill the pri blades for bypass air, it encourages nozzle drip; drill the sec blades.
If the air valve dashpot is old, it may be slow to release & is worth a few $$$ to replace it & save some odd tuning problems down the track [ pardon the pun ].

You are in Fl, similar mild climate where I live. I have never needed a choke with a TQ, so for more air flow, I remove ALL the choke mech as well as the bar that runs across the top of the AV. This leaves a small hole in the AV from the linkage & I braze a thin plate over it. May not be needed, haven't tried it without it.
