Answer
Martin;
well the dist is in wrong. I would take out the no# 1 plug and take off the coil wire, now have some one tap the kep and keep tapping it with your finger covering the plug hole, soon it will blow off, stop turning it at that time, now with the dist. cap OFF look at the rotor and the no #1 on the rotor should be on the no@1 spot on the cap, and look at the timeing mark it should be on TDC or close to it, turn the fan by hand to get it to tdc, now it should be on no# 1 on the cap if it is close than you might just have to time it if it is way off you might have to re-install the dist. all on the no#1  plug and rotor on no#1 at the TDC spot.  ok
