GRRR... still no start...

Ok, last time I posted I stated I had a good blue spark on all four plugs. I checked the timing and fixed it as it was just a hair off. But then I found I had a leak around the carb base and between the manifold and block.

So today I put a little high temp pucky on the gasket between the block and manifold and it seems to have seeled real well. Went to try start and nothing.

Checked for fuel... good to go... check spark again... NO SPARK. I threw the old working condensor back in just for hopes... nothing... jumped around the weak sister key switch... nothing... so now I wonder if I burnt the coil?

I have searched on how to test the coil here and for the life of me can't find the threads... can someone spell it out for me? Any other ideas?

James the tractorless...

It is so simple, yet so very complicated when you fix one thing and then the opposite goes wrong too. I swear I had a brilliant blue spark on all four plugs, and I did not leave the key on, so I don't know why the coil would be burnt but who knows. I will check for the ammeter readings asap (at work now) ...

Thanks

To use this flow chart you need a working ammeter Each "tick" on the meter = 2 amps, mine reads high (Error) @ 2 ticks (4 amps) but is really 3 amps

You can use it on 12V conversions. Note the voltage measurements in upper left corner relate
only to the OEM Ballast (not additional Resistance), which would also be in the circuit of a 12V (2.5) ohm coil.

With the ignition on but before starting, you should see approximately three amps discharge. No discharge? There is an open somewhere in the circuit. Check the points first, as they are most likely to be problematic.

Three amps discharge as per normal? Crank the engine. You should see the ammeter flutter as the points open, stopping the current flow, and close, starting it again.

No flutter? The points are shorted to ground somehow (likely), or the system is shorted elsewhere (less likely but certainly possible).

Meter reading normally in all cases? In all probability the points, coil primary, and condensor are doing their job and the problem is likely to be elsewhere.
