I have a Tiger s6 Kit running a Pinto.

Ive always been happy with points ignition but thought id have a go at installing an accuspark kit in the existing dizzy for an experiment out of curiosity.

after installation i cant get it to fire.

non ballast coil so have run the Negative wire from the new unit to Coil Neg (via the already present low tension wire) and the new Pos wire from the unit to the Coil Pos.

im getting spark from the King lead and spark at all four plugs - i know the firing order is correct as it was running perfectly before and i haven't removed any leads.

why wont she fire??

just to check i swapped everything back to points and she jumped into life immediately and timing was fine etc...


im stumped.

I ordered one last month for my mgb, the rotor shaft was 180 degrees out as it’s keyed on the mgb. Roll pin removed and turned around 180* and it was sorted.

This would be my suggestion as well - check the spark vs timing.

If you are getting sparks from the leads, but engine won't run, then they are firing at the wrong time, suggestion above regarding being 180 degrees out is worth checking out.

If the suggested remedies don't work then maybe it's something else by coincidence,e.g. fuel pump.

ok thanks ill have a look at that, on the pinto (Bosch) dizzy its keyed too but ive made sure its lined up with point 1 when at TDC on the comp stroke so im a bit confused how that could be it...

If you suspect that the timing is out by 180deg, then simply swap the leads around on the distributor cap.

Finally got it to fire up by turning the dizzy but i the reason i hadnt had it running before was that i hadnt realised how crazy far i would need to advance!

I managed to get it idling well and then checked with the strobe and its waaaay off the timing marks on the pulley....is this normal?? if not any ideas how i could have arrived at this point, running fine but barely able to see the timing marks?

i always had it set to about 10 degrees BTDC previously so now im unsure how best to set it without the timing marks as a reference...?

Don't trust the timing marks unless you have verified them mechanically.
