Very hard to start r60/2
Very hard to start r60/2
The engine is timed properly so that should not be the case. I have got it to rev up just a few times before dying again.
I have ran out if ideas so please help if you can!

Could also be the carbs...you didn't mention what you did for them. Should confirm that the book specs are set and that the cables are properly raising the slides.

Fast. Neat. Average. Friendly. Good. Good.
Re: Very hard to start r60/2
Carbs were vapour blasted and refurbished with all new internals and have been checked for dirt and grime multiple times. The ticklers are the new type ones and needle valves are set correctly. No issues there I suppose. Might be that the carbs are just so worn that it might a reason but seems unlikely as I have had a lot more worn Amal carbs on british bikes.
The spark looks to be good and bright blue on both cylinders. New leads and caps also. I have had multiple magneto issues before with british bikes but the symptoms of weak spark have been easy to spot. The magneto is timed correctly too. I have checked it a million times but will check again just to be sure.
I guess that the magneto could ve the scource of the issues and I’ll have to look into that again.

Also, I just remembered the safety gaps on the magnetos. Those two "points" that are below where the spark plug wires connect to the coil...there should be a gap of around 10mm between the point and the tip of the coil/wire.

Safety gaps are just about 10mm.schrader7032 wrote: ↑Mon Feb 19, 2024 12:42 pmCan you measure the resistance from one spark plug cap to the other? Would be interesting to know what that is.

The resistance is 11,8 kOhms. I have no idea what it should be. Points open or closed does not make a difference. Altough I don’t think it should make a difference.

Re: Very hard to start r60/2
I have notes that the resistance should be around 17K ohms. So you're a little low. Not sure how significant that is.
