I've got an old 93 MXZ 470 that my son & I have been playing with. It's running too rich.

I have the service manual for the 93, but can only find the high altitude technical data for 94-98.

It appears that there were significant differences between 93 & 94. My 93 service manual says stock sea level main jets are 360 & 330 with pilot jets being 45. In the high altitude technical data I found it shows the 94 stock at sea level is 290 & 280 with pilot jets being 35.

I'm not sure what to put in the carbs to get it running well. We are just over 5,000' and usually run in 10-30 degrees.

Thanks in advance for the tech help!

Nobody has the high altitude specs for a 93?

My chart converts the 330 jet to 300 and the 360 jet to 330. This is for 4000' and 14 deg F.
