Predator snowblower jetting sugestions

[clintonior]

I have searched for this to no avail. Predator comes lean.. I know this. so some experience surging that may go away with half choke on. I want to get jets to straigten this issue out. I bought a bsp for my Thunderbird. and a 140 emulsion tube kit comes with a 36 main jet and 37 main jet. I'm probably gonna run the 37 on my bsp w/header and K&N air filter. I might try that 36 main on the Predator 212. any jetting tips I'm in massachusetts so were talking mabye -12F to 32F deg.

I drilled a jet with a #60 drill bit which is .040"(its all i had at the time) and used it in one of my minibikes and run it all winter. It ran clean and good until spring when the weather warmed up. It ran good well into the lower 20°s- not tested any colder tho cuz im not tough enough to ride in colder weather any more. That may be a good starting point for you.
