running on garage floor

 

and in the car

firing order correct?

[jime17]

Would it not then only fire on 2?

[Nick Warwick]

By the way i haven't watched the video yet.

I would go over the complete ignition system.

Check the plugs and leads (firing order).

Check the distributor cap and rotor for corrosion.

Coincidentaly have just started a similar thread myself as I have no firing in cylinder two yet there seems to be a good spark and compression so will be watching this

[Stevelee10]

OK. Well I have been over the ignition. Plugs, leads , Rotor and cap are new and ok. But what I've just noticed is that the loom is ballest ign but I've got a 12v coil. So maybe that it's the cause of my issues. Gonna try giving the coil 12v see if that improved things.

If it's not that think I'm stumped since it was running fine before I fitted it to the car

[Fast Ivan]

checked the valve clearances?

[Nick Warwick]

Are you running points or elec ignition?

[Dusky]

Firing order looks like it is 1 3 4 2 on your engine...  ( it is a bit dark on the video though)

Should be 1 3 4 2

[Stevelee10]

Well the valve clearance was ok. Cant see how that would change moving the engine 6ft and I'm on points ign

[KernowCooper]

9v ballast feed to a 12v coil produces a very weak spark, do the 12v feed and see how it works then.

[Stevelee10]

Sorted. Seems I got a bit carried away with the problem. Turned out to be a bad plug on no1 but I still need to sort the ign issue as it doesn't run well with the ballast but runs great with a direct 12v.
So thanks for the help
