Predator 212 rejet

Looking for some advice on what to use for the rejetting of a predator engine on a project of mine. I'd just as soon buy a jet and drop it in as opposed to attempting to drill the stock one out. Also will this add any hp to the mix? Forgive any possible ignorance, I'm just starting to learn about small engines. Thanks everyone!

I just did a predator swap on a Troy bilt. I drilled the jet out to .034 and it was too rich, caused a high speed mis. So I had a Honda jet and drilled it out to .030. And it runs way better.

This is good feedback. What is the original main jet size on the Preditor 212cc? just trying to get an idea of the change.

Here is a supplier that sells jets at $2 each. The next available size up is .034.

When you drill to open the hole it is likely slightly over the drill size. If you do it by hand it may come out oblong.

From searching, it looks like the stock jet on the Predator (0.028) is too lean for cold weather snowblower application. Several have performed hand modification running a small 0.030 drill bit to rejet to 0.030.

The BSP site listed above now has 0.032 as an available size and next increment above the 0.028. Would that be a good option? I'd rather get one that exists then try to do this by hand.

This would be for Central New York weather, on a Ariens 10M6D repower.

thanks

The .028 is the stock size. You would probably want to try the .032, and see how that works.

I tried the .032 with the air filter removed and it ran superbly.
