Thermoquad issue or MSD box?

Phillip: It takes very little to restrict a passage in a Thermoquad Carb (really all carbs are vulnerable by the Thermoquad is the worse in my opinion). I find some fine wire like armature wire and GENTLY work it thru all metering passage possible particularly the emulsion tubes in secondaries! Also check floats for height and see if they have absorbed any fuel.

I bring a half dozen extra race ready tested Thermoquad to the races in my trailer and ANYONE is welcome to borrow one to test for a pass ( No ... you can not take them with you home ).

Phillip: I will be up there for Nat's in July and can give you a hand and we can try a couple plus I have half the MSD truck for spares(Also recently tested) in my trailer!
