I have a thermoquad question..The one im using on my 440 has an annoying whistle at idle and if i press on the primary throttle shaft, it quits..how in the world can i fix this?? Also, i am looking for a second thermoquad to build and i am wanting the one with the bigger primarys and no emmisions stuff beside maybe the 2 air bleeds that are inside the choke tower that you plug as thats not a problem, If anyone has a good rebuildable one like this affordable please message me.
Thanks!
