Well, this morning we tried the Commer and she wouldn't start at all, fired a couple of brief moments but nothing more.
So, back to basics. We reset the timing, she was a fraction out. We re-checked all the HT leads were connected in the dizzy. Then we checked the plugs for a spark, it was there but not very good.
We then checked the contacts for a spark, it was awful and not consistent. So we cleaned and reset the points and cleaned all of the plugs. We then checked for a spark and it was much much stronger. But, trying to start her again there was absolutely nothing, she didn't fire once.
We checked the carb and there is plenty of fuel getting in there, so much so that she kept flooding.
We are left scratching our heads again.
