I just bought a nice 2000 Trail Boss. I'll be taking it on a trip up in the mountains.

I haven't been able to get a service manual yet. Does anyone know the main jet size and needle position to run at 4000 ft?

Any feedback is appreciated.

According to the factory service manual:

Model ES32PFE02 for elevation
0 - 1800 feet
below 40 degress 147.5 above 40 degrees 142.5

above 1800 feet
below 40 degrees 140 above 40 degrees 135


Model ES32PF04 for elevation
0 - 1800
below 40 degrees 150 above 40 degrees 145

above 1800 feet
bleow 40 degrees 142.5 above 40 degrees 137.5

 

thanks very much!

 

Hey sgifford, Have you taken your carb apart yet? If so what size jet did you find in it?

Thanks, Caanan

 

I did take the carb apart to clean it after the float stuck. Silly me, I didn't write down the jet sizes. It hasn't been uncorked or anything, so I assume the jets are stock.
