Running a VBB engine on the bench?

[theboldjd]

Hi All

I have an old engine i picked up and i am trying to get it to run.... changed all the bearings and stripped and cleaned etc.

Wiring is causing me pain in the brain... I bought a 6v stator plate and coil (indian stuff from beed speed) but no spark i think i am missing something simple.

In the pics it doesn't look like you've connected the stator to the coil. Is this a test 😉

It is testing me!!!!

I am working under the assumption that the red wire is 6v from the ignition coil and that the black wire is earth, but no spark

I am ignoring the other wires but assume that the green is for the horn and blue/ yellow are for lights etc.  

I have two different coils but i cant find any combination that will give a spark.  

Im starting to think the flywheel magnets are the fault but that is a guess.  

This is the 6V stator Plate.


These are the coils i have.

Ha ha, I feel you're pain.

Ignore the coil for now, do you get a spark from the red wire when you kick it over?

Yes there is a spark now.... i realised that the points were malformed and could not close even though they looked closed there was a gap, i bent the frame of the points a bit a bit and now it is making juice. 

What coil would be best?  There were no electrics at all when i got the engine.

I got a 6V stator to keep things simple and i think the Fakealite (brown one) is the right coil, the grey one is off a CDI setup i think, will either work?

PS

Thanks for the help

Good news. Either coil, it's just that, nothing fancy. Looks wise the red one
