So...I’ve always had some trouble running for idle with this motor and I realized now that it’s because I was setting idle with the restrictor in... set it without it and everything seems good now.

im almost through break in so hopefully I’ll get to do some tuning this weekend.

What did you set the idle gap at?

The thickness of your Xacto blade (.5mm) or so.

You set his gap?

.7mm
I have drill bits that are .5mm and .7mm I use to set the gap with

Did your Nova manual say that was the correct gap? Seems like .5-.55mm is more common.

wow going back it says .6mm. Idk where I read .7mm

I've not dealt with any .28 engines so that's why I suggested checking the manual. .5-.55 is pretty common for .21 engines.

I have learned that you should set the idle gap with the restrictor removed. That can make a difference. Hope this helps

Hi All, Does anyone have a clean Nova 28 crankcase (stripped and no bearings etc required) for sale? Preferably 7 or 8 port current generation. I race tether cars and plan to use one as a donor for a rear rotor project. Cheers, Scott

I have learned to adjust the HSN and LSN to the max performance and adjust the idle to it.

At this point I just need it to get around the track haha. We’ll worry about performance when it counts.

I’ve got a couple more heat cycles for break in so I’ll try with a bit smaller idle gap and adjust accordingly.

Also with a break in you adjust the needles to what you need to run rich and adjust the idle to it. For sure with a break in there is no way to hold on to a given idle gap, that will never work.

im not quite sure what you mean
the box settings have seemed to work for the break in heat cycles. looks/sounds rich and holds an idle decent
in general once its gone through heat cycles i should set high speed then low/idle?
