I thought about trying to straighten mine out but I wasn't sure if it might have stress fractures in it or not after all the bending. Didn't want to take a chance on it breaking.

I suspect that you have the low spd needle set too lean; would suggest that you richen the low spd needle a bit & then set the high spd needle for a rich two-stroke at wide open throttle (WOT).

The instructions are good except for the recommended 2 1/2 turns out for the high speed needle. The engine will flood at that setting. Most engines reportedly wound up at about 1 turn out, as did mine. My engine idled fine with the factory setting of the low speed needle and the instructions are ambiguous, so I left it alone. Here are a couple of links to threads about the engine that you might want to visit:

Hmm,

They had goldenduff as a registered member. They also had a Paypal payment with payment & shipping address. What more did they need?

Hi Golden,

These NV guys must be pretty flush when their procedures are more important to them than selling their products.

Yes, I received mine some months ago. Don't know what the issue is with yours. Moderator?

Hello All,

I bought this engine today! Looking forward to playing with it on the test stand and later in the air. Now where can I find a 40 -size Ugly Stik?
