Hi,I would start off with a 130 then work backwards until it runs clean without spluttering.
You may end up around a 123 / 125

hello,

The 123 is short.
The 130 does not let up revolutions the engine.

Right now I have a 125 with a return air screw, not up revolutions the engine.

A question, you have to adjust the air screw?

thanks

Main jet has nothing to do with the air screw adjustment ,can you be a little more specific with what info you require?

my engine does not work well 123, 125 and 130.

They say a 123/125 is optimal for my engine, but I do not work. The engine not up revolutions

It may be by adjusting the air screw?

possible solution?

Hi,I take it you have a 200 jetex carb and not a 150 as the slides are different,you should be running a 48 pilot jet if not change it.

The engine not up revolutions :wtf: will it tick over smoothly?sounds like you my have others issues.

My engine is a 200 with Jetex 22

It used to take a 118 main jet with standard filter and the engine revolutions is good.

Tino Sacchi Filter and 118 ill.
I tried 123, ill.
I tried 130, ill.
I tried 125, ill.

The 150 slide on a jetex has a cut out in one side of the slide the 200 doesn't simple
