'78 Brat keeps stalling

[YellowSub]

A couple of weeks ago, my Brat started having problems running. It would start fine, go about 20 feet, then die. My husband found that the points were burned up. We replaced the condensor and points, cleaned and regapped the plugs, and adjusted the timing. It ran great for a week, then started stalling again. Once again the points were burned up. Replaced everything again, checked voltage. A week later it started again. We've replaced the condensor and points, but now it also looks like the choke is getting closed and it can't warm up. Any ideas?

The points issue sound like

1) Bad condersor (since you changed that maybe rule it out)

2) Ballast resistor by passed or shorted.

It's mounted on the coil.

If it is by passed too much voltage is put on the points.

Here is a picture

PS change the dist to an electronic one

See my post "dist conversion point to electronic"

 

 

The choke issue.

I just had to change (repair) the heating coil in the

choke housing on one of my 78 Brats.

If it does not heat the bi-metal choke spring

the choke stays closed.

 

My heating coil was broken right next to the connection screw.

 

I can do pictures of this problem.

If you want me to please ask.

 

EZ test

remove air filter housing

plug vacuum lines

start engine

wait two minutes

feel choke control housing

should be very warm to the touch

and choke should be open.

 

Hope this helps
