I'm using that puller http://www.amainhobbies.com/product_...nk-Trigger-Red It mounted on the closest hole from catcher. Does somebody has the same problem with it?

Hi.
Just tried the 6 mm venturi, and the smaller throttle gab. Engine still screams and have great bottom and top. I'll find out the runtime on sunday at a race.
One thing I couldn't figure out: From the point where the engine goes from 4-stroke to a slow 2-stroke, I had to lean the HSN almost 1 turn to get her really sing on the straight (not too lean)! Is that due to the small venturi, throttle gab or the Nova carburator?

remember very small adjustments once you get it close to tune with 6mm restrictor , like 1/2 hr increments
you will see killer runtime now that your engine is properly jetted

Ehmm... The E.P.A of the spraybar with the venturi in place.Cool. Thanks for the advise, Monty

I was told yesterday, that a smaller venturi gives more bottom and less top... I thought it only reduced the overall power of the engine.
