The same nasty too small idle mixture jet. The jet from hell. A #44 will make that motor purr like a kitten.

Thanks Almetelo.

Its a slightly richer (larger hole inside) low speed jet in the carb.. The 95 is the main, larger jet.

Plus one on either draining the bowls after use or use a fuel stabilizer as well. Those little jets will varnish / gum up closed within a month without fuel stabilizer, EVEN IF YOU RUN IT DRY.

The little bit of fuel that remains in the bowl is just enough to cause issues..


Part #7 is the low speed jet;

It means if and when you start having fuel issues, that carburetor cleanings won't cure, that you can remove the idle mixture jet that came with the motor and go to a slightly larger jet size.

In addition to the idle mixture jet, there are some incredibly small pasageways/orifices within the F40 carburetor.
