2mm gauge can anybody help me i need to set my low end spray bar in my th pro .46 glow engine is their a thing called a feeler gauge for this and how can i purchase one anyadvice i had to replace the spray bar?

2mm is roughly .080" so if you have drill bit this size, it will work as a gage.

Are you trying to set thelow needle mixture adjustment?

I just eyeball them and then run the engine to see where it needs to be

Ditto:

You could use a 2mm Allen wrench....or a piece of .078" (5/64" ) music wire.

You will probably find that 2mm will be way too rich. The Tower .46 can be a bear to tune on the low endto get a good transisiton to high speed. Patience is a virtue with this engine, but once set up they are a power house.
