I recently picked up a used 1994 formula MX with a 470 liquid cooled twin. It had been sitting for years and after cleaning the carbs and doing a compression check I found that the Mag side piston was cracked halfway though.

I am planning on putting it back together this coming weekend, but I was wondering if anyone has the stock settings for these carbs.

This and any other information on the sled would be greatly appreciated.

Sincerely,

Jason

1600 -1800 RPM warm
Help Needed, cleaned carbs on this sled and only screw im seeing for adjustment seems like it reqyires more than justbone and a half turns out? It has a Philip's head and a spring..... it will fire up and run while manually pumping the primer and will run strongly at higher rpms but when idleing down it runs out of fuel unless i keep pumping at idle.
