Massey Snowmobile Question

[Anonymous-0]

Thanks for the help with the fuel mixture question. Here is another question. Can someone tell us how to adjust the carb on it. It has a Walbro WRA-37 carburator. Thanks for any help.

Idle & high speed mixture screws start at 1 turn out.
Re-adjust as needed when running.

My Massey Ski Whiz all have Tilotson Carbs, I can still get the kits, the Chinook I'd have to look and see. Two screws, one is low idle one is high speed.Mist some fuel into the carb with a spray mister and get it running then keep turning the low speed screw from all the way in to where the machine will run and idle( up to 2 turns I'm guessing.) The high speed will maybe be three quarters of a turn from in position. The high speed screw will lean out the fuel air mix so it can be adjusted by taking a ride and adjusting a quarter turn at a time until it has lots of zip. I don't have any manuals for these machines. My old TNT Skidoo was 7/8ths on the high speed and it would fly.
