I had one of these and the timing was out ever so slightly similar issue. Did you put the leads back the right way round as well.
First thing first though check your getting a spark?Take a plug out and put it in the HT cap and then rest the end of the plug on the metal engine, earthing it. Get someone to help and see if plug sparks. Do this to each plug, should be nice and bright and blue.
No spark is
Plugs
Caps
Leads
Coil (already changed so this is ok)
And then cap etc..
If it is sparking then its probabaly the timing or similar.
Post back how you get on
