I've got a MS usx-37 carb on a 310 Oliver motor. I was going to send it to Motec, but he said that the carb is junk and that he wouldn't touch it. Any suggestions?
 
I have a usx-21 . That is hard to keep tweeked in tune . I have taken it off several times but it always finds its way back on the tractor . 314 cfm that it flows is hard to beat unles you go to a stromberg from a plane, tank or train
 
i've had one on my 77 for the past 8 years and it has been great. the only mod i did was to enlarge the inlet valve to give it more gas for high rpms for tractor pulling. when adjusted right it makes good power and good fuel economy. last saturday i plowed for 5 hours pulling 3-14s in 5th gear and used 9 gallons of gas. so in my opinion its a good carb. chuck
