Hi:

I have a 11/33 Cub Cadet , the info on the metal tag on the side of says on a yellow metal tag
Techumseh Products Co.
Engine Model ohsk110 221701a (H)
Engine Family WTPXS.3182AF
Displacement 318
D.O.M. 8236 R

The Model information on the sticker on the cover below carb area is worn off.

I would like to find a manual for it if possible but obviously I need to know what to look for.

I'm having a bit of a problem that just started a week ago, when it gets into the deep snow it starts backfiring and then shuts off. I have taken the carb off and cleaned it best I could but I'm not sure which position the bowl should be in as far as securing back on as the drain on the spring plunger is possibly in the incorrect position. I'm hoping I can get some help with the issue I'm having as well as some input as to where to set the idle Speed screw the one with the screw/spring. As well if the float has a certain setting set with the tang. I have worked on motorcycles with carbs but never with snowblowers or the like.
Near as I can tell Googling the above engine model number it has a Tecumseh 640169 - Tecumseh Carburetor
Thanks any help would be appreciated.
