Predator 212cc Carb Jet

Putting a Predator 212cc in my Ariens 910018 Ariens, with an 8HP Tec. I am in Vermont, and it does get cold here, (not so much this year, so far) -0 at times. I want to replace the main jet, and found an adjustable main jet on Ebay, for the Predator,
eBay item number:
321975078268. Has anyone used this, and what are your recommendations for cold weather for this engine.

The adjustable jet is a good choice. They are made by a member her. Or at the very least, drill the main out to .032. I think a #77 drill bit is the correct size.

Would this jet work on the 208cc chonda? I havent had any lean issues in the few hrs of runtime, but modifications can happen!

I have not run my Predator 212cc in that much cold weather, but it seems that I can just adjust the choke slightly to deal with any lean running issue. Usually during the first few minutes of operation.

If your having to adjust the choke to address the motor hunting. Your running on the lean side. With the air cold like it is in the winter, to will make a lean condition worse. One of the machines I did last summer with a predator swap, ran great in the summer, with the jet opened up to .030. But I went and tested it a few weeks ago. And it was hunting a little at full throttle. So I had to open it up to .032, to get the jetting right. Now you probably way closer to sea level. I'm about 600ft above. So your's may not be as bad.

I have the adjustable jet kit in a 179cc Powermore and it works great. I bought the kit with the oversized jet (.055) so didn't have to do any drilling and even with that huge jet it was easy to adjust the engine to run smoothly. Roger

You will have issues as soon as it gets a bit colder. You don't want to run lean or with the choke on. You are better off slightly rich than slightly lean as the engine will run cooler.

Who knows what your jet is right now. Did you measure it with pins? Stock jet is .028". The Chinese have been know to make mistakes. It may be drilled oversized.

I am in MA just about at sea level and I had to open the jet to prevent hunting in mid-30 degree weather.

My advice is get the adjustable jet or buy a new .032 jet on OMB or ebay. Either way, it is not very expensive and good insurance.
