Update, I've been playing with BIG JOHN, I'm down to a 330 from the stock 400 main jet... it's responding really well. I'm going to run it for a bit and see where we are...Still is a little rich mid range..

Can someone please tell me what main is supposed to be in it. Previous owner had a 400 in it YIKES. Thanks in advance.. I'm pretty sure it's a 34vm slide carb

UPDATE: So I found a used stator. Tested great. It was in a 440 liquid. I tested 8 different motors at ONE sled salvage shop.. Long story short, three pulls after reinstalling motor and BIG JOHN LIVES. Now to get the seat back from upholster and away we go...
