Hi guys,

I am running a standard 231, with a Hatori and the MA air filter. I am wondering what the needles should be set at.
I started with MA's suggestion of 1 1/2 open on both. This seems far too rich and smokes well.

My low needle is currently at about 1 turn out and it has cleared up quite a bit. Is this a bit lean?

Std gas and Amsoil.

Thanks.

All carbs will be a little different, but is sounds like you are getting close, MIne high end needle is about 11/8 and my low end is about 3/4 Hope this helps..
What oil ratio are you running and what fuel? gas or kersone

Hi Helinut

gas or kersone
I think John meant " gas or camper fuel". Being the UK, my guess is gasoline.

Yes Gas not camper fuel. Amsoil at 50:1 as recomended by MA.

I am buying Amsoil from RC-Bearings .com

Hmmmmm

running a standard 231
1 3/8 on both needles to start, the low could wind up AFTER BREAK IN around 1 turn, but probably not less with the 643 carb.

IMHO, you are too lean for breaking it in. Fatten it up.
