Still overheating

Just another update:

I had some spare time last night and ended up backing out the air mixture screw maybe half a turn, maybe 3/4 of a turn, from where it was. Adjusted the idle screw out to compensate for the increased RPM and took it for a couple test drives of about the same distance as previously. No issues with spewing, no dieseling.

But it does take more work to start than it used to. Previously I was able to turn the key and the engine would immediately fire up. Now it takes both some cranking and accelerator work to start it. Still, I'm closer to where I think I want it to be.

I'll take a look at the plugs later this week to see if there's any obvious damage from a lean mixture. I'll probably pick up a new set anyway. I don't trust my mom's mechanic at this point to have serviced it well. Did I ever mention that it had a massive oil leak when she gave it to me? Her "mechanic" had not tightened the valve cover screws... Must not have been used to anything without a computer.
