The truck has had a hard life, and I am trying to use it, but am trying to be easy on it at the same time. Yes the 2 springs under the breaker plate, my father gave up back in the late 70's cause he thought it jumped timing, I got lucky and saw a piece loose.
I'm still running pure water till I figure out the problem, have animals running around.
The cap is loose, just there to keep dirt out to save a rad. Same problem tight or loose.
Yes the dist advances when revved.
I'm convinced a head gasket but just making sure. Dad says it should mess up quicker if blown though. I have probably ran it 15 hrs now and 20-30 some loads of gravel.
