No. Thats the a/c jet.

The main jet can be seen if you remove the bolt from the front of the carb with the carb off the engine.

Grp A Carbs

This is always confusing!!  Some people say they have a GrpA just because the choke flap has been removed, this isnít the case.  A lot of time and effort goes into a GrpA carb.

Yeah, thats the problem Mike, i mean a true Grp A carb has a 150 main, larger venturi & a larger brass aux venturi, so in reality not many people do have a true grp A.
Alot of 'tuner' carbs have the venturi bored out from 25mm to 27 or 28 a larger main & a smaller air corrector, some have the choke removed, some don't, some have a standard sized venturi & larger jets.........

Is there any point in a 150 main jet?

My car came with a somekind of tuner special 'grp a' carb, just looked standard to me with a 150 main jet and a 0.9 a/c.

It was a pig to drive off boost with lots of hesitation, and i swear i used to see a flame or two out the exhaust on overrun.

150 main was ok for the cars running in the Grp ! series, waste of time on the road but it's an easy way to get more fuel into the carb when people turn the boost up, 1 50 main & .9 A/C is way overkill for most engines & yes it prob did spit flames out.
