New carb question

Hi all.

After searching this site I bought the recommended carb for my Sno Thro. However the choke lever looks like it's backwards. I couldn't find anything on here how to rectify the problem. Any suggestions appreciated. Below is a picture. I have a 1972 or 1973 Six horse tecumseh.
Thanks,
Cliff

Well i got the new carb and after switching out the choke stem with my older one she fired right up. That carb worked perfect after switching out the stems. Everything works except the augers dont spin. Everything engages fine that i can see. Any help would be appreciated. I pulled the two bolts off the auger shaft and they were fine. I think those
are the shear pins.
Thanks for everyones hep.

That's going to be a problem. That doesn't seem to be the right carb.
What is the new carbs part number ?? Is there a part number on the old carb ??
What is the full number of the Tecumseh engine itself ??

Any chance you can interchange the chokes and use the old on the new ??

Does the new one have a nipple for a primer ??

What's wrong with the old carb? Looks a little grimy on the outside but is there anything terminally wrong with it that a dental pick, carb cleaner and maybe 10 minutes in an ultrasonic cleaner wouldn't fix?

It was leaking very bad. Plus it was all bent up on the backside from the old owner trying to get it off with a pipe wrench.

No nipple primer. That's what I was thinking maybe drilling the old and new one out and tapping with a screw? Below is from ebay. I could not find one with the choke facing the right direction. I'm thinking possibly bending the new one straight back and maybe it will fit through the cover if not, add an extension somehow.
Thanks,
Cliff

That's what I was thinking trying to switch out the choke levers or bending the new one straight back and flat then attach the old one to that to extend it out. Below id the one I ordered. I have the H60

Well i got the beast running like a top. I also pulled the gearbox apart and found a broken pin that slide s through the auger shaft. Bingo everything works. A very big thank you to this forum and it's members. Now i need to figure out how to remove and replace my zerk fittings on the auger shaft. Don't know how the come off.

Congrats on getting her running Cliffy!

make sure the auger isn't seized to the shaft before going hog-wild on the zerks. If it is seized, you've got bigger fish to fry.
