Am i the only one around here who has at one time managed to screw in the jet upside down? Yeah? ..kay then lol.
i dont know how it managed to screw in upside down either. But it did.

I wish I could get mine out. ;(
Is the carb jet like the predators? and if so is yours upside down?
When mine was upside down i let the carb dry, used a small(not too small) piece of duck tape -sticky side towards the jet-, applied pressure to it with a flathead screwdriver, and loosened it. You may need to use 2 layers of tape.Maybe 3 if you need extra grip and pressure.

ugh how can I tell if it's upside Down I can see the little notch for the screw driver It fits but the jet will not loosen up for some reason

To me it sounds like the carb is like the Predators' , so..
Assuming the carburetor is on the engine,screw the jet to the RIGHT. Not the left.
If it's off the engine, with the bowl facing UP, THEN you can turn screw the jet left to loosen it.

I think the first time i ever took off a jet i had to use vice grip pliers on my screwdriver to get it out. Just be very careful not to scrape the threads with the screwdriver.

Oh I'm going to have to try that and I might have scraped some threads all ready ... Whoops ... Today I started it up and I pushed the throttle arm back and it was delayed and seemed less powerful (I put a air filter and a modded exhaust on it) I can feel hot air coming from the exhuast port so I think it could be leaking do you think that is what is causing this

You need a bigger jet.
More airflow = more fuel flow being needed.
Will run lean otherwise.

Brent is right...you need a bigger jet!

Sacrifice the jet that is in there and use and "easy out"? The hole is tiny that it screws into. I have that "special" screwdriver that I ground the sides off of to get in there and have a good bite!

Oh thanks guys would a new emultion tube and new idle tube (idk what it is called maybe a low speed Jet) help also And your saying that since I have more air the engine cannot run at full perfornmacr without more fuel. ?
