You say you have spark. How sure are you, it's at the right time? You can check this with a strobe attached or crank the engine manually and listen closely for 'cracks' while watching the timing marks. Has the advancer been apart? Also check spark isn't 'leaked' from plugcaps and/or HT leads to the head.

Pretty sure most manuals will explain how to set static timing with a simple test lamp arrangement it's not as accurate as using a timing light but certainly good enough to get her running.

I'm using an electronic ignition with an integrated LED, so that should be ok

Hey,

So I spent a couple of hours on the bike today and I figured out a couple of things :
1) not all the spark plugs were firing, some were dead or even the wrong ones! Now I’m about to order some new ones but I’m not sure if I need to take some resisted one or not. I’ve put a photo of my plugs below
2) the electronic ignition was slightly off, apparently the mark F14 need to be aligned with the mark on the crankcase when the LED is switching on. If someone can confirm it needs to be the mark on the left of the F that would be great.
3) I’ve followed your topic to set up the float properly @Julie. Hopefully that will work and not overflow.

Looking forward to get it started!
Thanks for your help everyone

Tom

With those resisted plug caps fitted, you need to fit non resisted plugs. (D7EA)
