No spark...need someone else's point of view.

I've ran the pertronix style system in my Harleys, VWs, 6 cyl Chevy van and my Ford Maverick 6/8 cyl. motors.
Hummmm...my 52' 8N Ford tractor may be next....

 

Endorsement from personal experience. I purchased a factory duraspark unit from this guy scott@reincarnation-automotive.com. After giving him some details about the vehicle he sent me one curved for my application. I already had an old duraspark setup in the car but the dist was giving me problems. Holy freakin' cow batman!, a properly curved distributor makes a big difference in the old seat of the pants meter. Of course you can recurve it yourself from articles on the net, but I needed a rebuilt distributor anyway.

 

Would you be comfortable posting the specs that it was re-curved to?
I'm just curious.

 

What he sent was the amount of vacuum advance at the distributor up to 2900 rpm, at which the distributor is fully advanced. If you add your timing advance to the distributor (vacuum) advance, you will get the total advance for the engine. My timing is set to about 10 degrees BTDC, so at 2900 rpm the total advance would be 29 degrees. From what Scott said, he uses a Sun machine with the specs you provide to set it up. I was skeptical of the difference it would make, but I could feel the difference in the car. I cannot recall all the specs he requested, but I do remember sending the engine size, cam specs, transmission type, rear end gearing, possibly the tire size along with other info.

1000 rpm 2 degrees
1500 rpm 6 degrees
2000 rpm 12 degrees
2500 rpm 16 degrees
2900 rpm 19 degrees

 

Vacuum advance only operates at part throttle and is no use at WOT...

Specs are for mechanical advance which consists of a pair of weights and springs in the base of dist...

 

will this fit Scoopers tractor...

 

Depending on what engine I put in, it might...
