dt175mx main jets

Hi

I've got a 1981 DT175MX. The carb on it, which I believe to be original, is model no 2H501. My Haynes manual has the spec for a 2h500, but not the 2H501.

What I'm trying to confirm is the correct main jet for this particular carb. The bike came with a 170 fitted, and I reckon that's too rich - the bike struggles to get through 6000, but once through 6000, it takes off. Depending on what you read, it seems 130 or 160 are possible std sizes.

Obviously once the main is sorted I can then fine tune the needle setting.

Anyone able to help?

Many thanks

Lee
