[TR] Stag, TR6, GT6 Stromberg Carbs

[Frank Magnusson]

Thanks Dave,

You're right.  Turns out it is a port to the bypass valve, which the US Stag carbs had but the UK ones did not.  Same as TR6 which has that slot in the insulators.  Will either order a set of TR6 insulators which hopefully are the same thickness or just cut the slot in the ones I have.

Thanks,
Frank

I believe it is for the over-run valve and perhaps one of the other control devices bolted on the side of the carb.  Those may not work properly without the slot.

The original insulators have a slot on one side that mates to what appears to be a passage on the carb face (the side with the 4 attachment bolts).  BUT the new insulators and gaskets from Rimmers do not have this slot at all.  Wondering what the purpose of the slot is and if I need to have the insulators machined to have a slot cut into them or if they are ok to install as is without the slot.  ROM mentions to align the insulator with the slot as does TR6 guidance.  Stromberg overhaul manual doesn't even mention it.
