it turns out I was Timing it on the wrong stroke as i forgot the ratio was 2-1 for the crank. Thanks for your help everyone. non starter..blowing thro carb?

Good News, i have got it started it turns out I was Timing it on the wrong stroke as i forgot the ratio was 2-1 for the crank. Thanks for your help everyone.

Re: non starter..blowing thro carb?
Nice one, glad you got it sorted.
That was the reason I originally said to swap the leads 180 degrees, if it was timed up on the exhaust stroke that is 180 degrees out.

Re: non starter..blowing thro carb?
Yer i am still sort of lost as to why it didnt work the first time. when i swapped the leads. and when I tried it on the correct stroke it worked with having 4 first. then when I tried to swap it round to the correct way i got lost again ahah. but got it eventually so all is good now to find an exhaust and will be good as new
now to find an exhaust and will be good as new Re: non starter..blowing thro carb?
Did you start from scratch again and pull the dizzy out again when you got it running? Perhaps you were just 1 tooth out on the dizzy the first time 
ah well doesn't matter now, the main thing is that it now runs

Re: non starter..blowing thro carb?
This timing issue has cropped up a few times now, here and other forums. So I have photographed this from the workshop manual. The main problem seems to be setting the timing 180 Degrees out on the exhaust stroke instead of the compression stroke. As the manual instructs you to take the rocker cover off to make sure the number 1 cylinder is under compression (rockers not touching valves). But who wants to do that and bugger up another gasket ??
I would suggest removing the spark plug and offering a short length of a suitable size hose into/onto the plug hole. Then try blowing down the hose, if it's hard to blow down then it's on the right stroke. Likewise if it's easy to blow down then turn the engine 360 degrees and try again!
Of course make sure everything is really clean so as not to allow any dirt to enter the cylinder
I've not tried this, so any input would be good. At the end of the exhaust stroke (10degrees before top dead center) is the exhaust valve still open a little if not this theory wouldn't work.
