On the LHS of the LH carb (the opposite end to the one that has the bellcrank on it) there is a hex connector that has an internal thread in it.

This is the perfect location for my TPS and no doubt others have fitted theirs in the same place.

Does anyone know the thread size so I can get a stud to fit it. ID is about 6mm so I'm guessing it would be 1/4" UNF but I thought it would be metric.

Is there such a thing as a 7mm bolt?

Tried all the standard and odd bollts I have with no joy.

don't know the thread size of the dellorto but m7 bolts are available, usually they have an 11mm head but arn't a commonly used size.

Thanks guys.

Worth a try with the M7 at that price.

Certainly M8 is too big and M6 too small so must be something in between.

I might ask DellOrto just to be sure.

this any good mate? cant see it being metric as nothing else is lol
