only an observation of the system u explained i know this from wen i ran the ninja and the os it did and that was the out come at that stage .5 or .6 with the venturi in or out

Wow do i Love this motor in Truggy.....BY far my Favorite truggy mill By far.

Especially with Clockworks tweeks.

Do you set the idle gap with the insert out?

No, tune the engine as you would run the engine.

YES. ALWAYS set the idle gap with the venutri OUT.


Its a Big Misconception among some guys but its been proven true Many of times.

please explain.

If you take out the venturi to set the idle gap, doesnt your idle change after you put back the venturi because your closing the hole more?

I don't think the insert will effect the idle gap as there is not enough air flow through the idle gap for the insert to have any effect, and from what I can tell the insert has about a 2mm gap under the idle gap.

Yes, but your not tuning to the idle. Once the idle gap is set you tune the bottom end to the idle you want.

If you want to set the idle gap by measurement, taking the insert out is the way to do it. The insert widens at the base and does not close off the very bottom of the opening and thus doesn't change the idle gap size when you put it back in.

it sure was running like a beast yesterday ! your truggy looked like its front tires never touched down all the way down the straight LOL

I ask this same question to Ron ( Werks Guy ) and he told me to leave the restictor in the carb when setting idle gap.

is there any video,s of a b5 whit 2013 ???????'

ive never seen one

Who is Ron the Werks guy???

Lol, sounds like I'm getting a name like Larry the Cable Guy or something! Regarding the air gap I always set it with the reducer in. Maybe I'm a little strange but what is the point of setting an air gap to a specific measurement and then blocking part of that off by installing the insert? Also when you are tuning on some random guy at the tracks engine are you really going to start pulling out inserts etc? Again though please remember that this setting is not something that needs to be exact, so just look down the throat of the carb and adjust it. Should take about 4-5 seconds to ball park and then be done with it.
