Too rich?

Okay great! I was just confused, because it’s the stock jet being used, while more air is coming into the engine because of the air filter. And more power feels like it’s being made.

Any idea as to why this jet still works good, I’m still curious?

What kind of air filter is it?

Generally speaking, a free-flowing air filter necessitates larger jets because it reduces restriction. That lesser restriction means there is less vacuum pulling fuel through the jets. The air is also denser and requires more fuel to keep the mixture good. The choke works in a similar way, just much more dramatically.

That makes me wonder if perhaps your air filter doesn't flow as well as it should.

Edit: I do have a foam pre-filter on the high flow air filter; and it has been oiled when i got it. Now I don’t know if this constricts airflow too much just yet, but when I get home I will take that off, and put in the .038 jet instead of stock

I’ll get pictures up shortly In a few hours if it helps
