Can someone throw some light on what I’ve done. Just done the valves gaps and now it won’t run just pops and farts. 1st question is does the number 1 piston need to at tdc. I have assumed it does. Do the cams need to be spot ( they are as best as I can see) . There is petrol and a spark . Any help ideas would be great.

 

If you're talking about putting the timing chain back on, yes to cylinder #1. Get a shop manual that will show exactly where things need to be when putting the timing chain back on as well as the cam gears.
