Final update, I hope
New plug in #4, slight improvement in heating, I had turned the pilot out by 1/2 turn
Idles OK, blip throttle returns below idle and then back.
Backed out all other idle screws by about 1/8th ish and it seems OK
Run at 5k let go of throttle, returns to about 1800, certainly under 2000, blip throttle returns to 1500 no stumbling.
I think without balancing with vacuum gauges this is as good as its going to get
Time to refit the plastics and give it a spin

The balance is close, I used a 1 1/2thou gauge with throttles closed, [throttle stop screw just touching cable drum.]
Should tick over evenly down to 1,200 rpm

I know it should, I'm not doubting what you did Dave, its within a gnats whisker of that and that is a massive improvement. it's good enough for me.arsey30 wrote:The balance is close, I used a 1 1/2thou gauge with throttles closed, [throttle stop screw just touching cable drum.]

Great,
Why not come over some time when the sun shines, then we can swap over bikes and compare them and you may well go on your way rejoycing :-)

Sounds like a plan, however i know my old bike wouldn't compare with your pristine example and I'd be too worried about damaging it!

It's the engine response and running I am interested in, and you would have a reference.
You can ride the nc35 if you are worried agout scratching it :-)

If your ever over this way you can ride mine too
Mine idled at a 1000 with the carbs way out of balance but you could really hear it running 'lumpy', the vaccum balance just smoothes it out more.
