Distributor Test Machine Demo
 

Ever wonder how a Sun test machine works?

Thanks for posting the link on the distributor rebuild. That guys is tops and so is his equipment.

Oh yea, he knows his stuff

I have that exact same machine and it has saved me countless hours over the years diagnosing and repairing dizzys of all kinds but mine looks it’s age and some of the functions like rpm and vacuum pump don’t work anymore. I tested a 6cyl lycoming magneto in one time, that was a little crazy. Obviously that machine has been restored and is sweet.
