Cold start timing advance?
 

I see my pump has the lever but nothing hooked to it.

Has anybody messed with this? maybe a pull cable to actuate it for the timing bump during the cold seasons to help with starting?

I think what you are looking at is the manual fuel cutoff. Useful if your shut off solenoid ever goes bad. You can use that to kill the engine. The cold start advance, or KSB, is located under that. It should have a wire to it. The I/Ced models power 12v to it to advance the timing to help on cold starts. After the engine is up to temp it cuts off power. The non-I/Ced engine are the exact opposite.

yep..

hit it after I fired the truck up after work and went ohhhh..... when it shut down lol

I fail at reading diagrams after looking at them for 9hrs at work
