Timing advance
« on: May 09, 2023, 09:04:37 PM »
Evening all, working on the 400 tonight getting it ready for the road and knowing I had to set the timing etc I set about it.

I’m having a real faff getting the test light to come on anytime before the T mark on rear plate, it simply won’t advance anymore. Any ideas?
Valves, done, cam chain, done. Points, done, just can’t get it timed. Any thoughts on my stupidity?

 The test light only just lights up here and I’m on full advance with no room left on the sliders……..

Apologies, as you were!

Sitting front of it now and I still can’t get me suede round it. The light just flickers on at that point but nowhere else will it light up over the full adjustment. Come on, put me out my misery Ken, there’s a good man.

Are you saying it times on 1-4 but won't on 2-3?

If so reduce the point gap.

Sorry Roo I thought the static timing was the easy  bit just follow the manual have you got it so the points with the blue wires are to the coil that is connected to 1&4?😁😁😁

Roo your setting the 1-4 points in that pic, the crank turns clockwise, so by turning the backplate clockwise you are delaying the timing, turn the plate the other way and check again.

The buggers been running

Just bring a real pig but just whipped 1-4 points off and although they might have been set at the front they very much weren’t at the back

That’s not good. Fiddling, will report back….

They were bent well out of shape so flexed em back to a right angle and it’s squared the faces back together. I’ll set the gaps again and have another bash…….

Bent that back round, sorted it straight away. God knows how that got knackered light that but straightening it has sorted it, happy days. Attention to detail wins against head scratching wins again
