Depending on what all was done to the motor? What size was on it? 34 36 ?
I would just find a carb off of a newer 440 like a 76-78 440 Jag or Panter or Pantera!

hi the motor is stock, but i,m going to rebuild it from the ground up, i am planning on putting a 2stroke pipe on it from an kx 250 i have laying around to see if that will give some more hp also, right now i have a mikuni carb on it from an 81 skidoo 9500 blizzard it had twin carbs on it, i got an intake boot from an late 80,s yammaha engine. I have to
check he size of that carb. The motor seems to run alright i mixed the gyas a little richer then normal, so i woundn,t run to lean and do some damage. when i got the sled the gauge said it only had 840 miles on it. thanks for any help.

stock it had wda-1, i seen on the alpha sports micro-p... the 77 panther 440 had a 34-vm with a 260 main jet, and the needle jet was a p-6 251. Does anyone know where i can get a new pto bearing for this engine. I'm having nothern crank shaft in minnesota do a complete rebuild on this after x-mas, but he said he did not think he could find one.
He said he could rebuild for 200.00, plus my shipping of course.

John is a real good guy! If he can't get it ? Have you looked at the bearing yet? You might be able to get a number off of it and try a bearing store?

No i told him i would not tear her down till after xmas, but i would like to do a complete rebuild on it, so i know what i got. Parts are hard to find for this but if you look hard enough their out there somewhere, just were is the question.....tommorow i,m going sand blast the slider, and paint it with rustoleum black, and where the tubes slide with each other i,m going to drill and put in grease fittings.sorry about the rambling got a bunch of ideas for this, alot of thinking. fun fun fun
