Thermoquad help questions

Then where does it go??

Also, I read in an old demonsizzler post that for performance you should drill out the accelerator nozzles to .031” (if I recall correctly, something close to that...)
Do NOT drill out the squirter cluster until you know you need a bigger shot.
The vent can and should be plugged, if the whole charcoal can setup isn't there. There is no one size fits all with squirters. Do not enlarge them if there isn't a problem getting out of the hole.
The vent should remain open and not plugged up since it releases built up pressure that occurs from time to time within the fuel bowls. Fuel will not spill out. Reinstall it with a dab of lock tight for piles and tap it in if need be until it seats.
I think the secondary throttle plates might hit with just the 1" adaptor. Might want to check that. IF you floor it and they wedge it will pin the throttle open.
The secondary side should have absolutely ZERO issues contacting the intake manifold when the spaced is used.
Zero, none, Na-da, Zilch, etc
