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.

Hey Bewy, is this picture hood for what you were saying?
Let me know via a PM. I’m pretty much done with this fool & how he posted this thread right now. I don’t think I can take another idiotic comment or an aloof type of response for someone who posts a million dumb *** threads and acts an *** on purpose. I’m not even reading this his dickheads response to me. I’m ducking done. Just trying to be honest here. I’m not angry or mad, just saddened but a moronic Imbecilic attitude from someone who’s thinks it’s funny I do such things.

Im moving onto those actually looking for help and have more than 15% of there brain power working while seeking help.

If you need or desire another picture, PM me and we will hook up on this TQ stuff.
