Ok, sorry again for the long delay between updates. I haven't had much time the past few weeks with Thanksgiving and some traveling for work. But good news, I took the Z on it's first drive since 06 yesterday!
There was indeed one major vacuum leak in the braided, curved hose going from the anti-backfire valve to the manifold. I found a hose at Autozone that worked, although it was not metric, so it's a bit oversized and it wasn't quite the same curve, so it's running over the top of stuff instead of under. Will try to find a proper replacement later.
I'm guessing some the other hoses are not completely air-tight at the connections. I did try to address that with some zip ties and hose clamps, but again, I just need new hoses. Will address that next spring.
Yeah, I see where you're looking. It's actually just really thick parting line flash on that hose.
I also continued to have problems getting it started, even with the new coiled. Turned out this was fuel. For some reason the new mechanical pump cannot pull anything from the tank without priming. Took me a while to figure this out, which was frustrating, but once it's primed, it runs pretty well. I stopped and started it several times and it fired right up once warm. I'm going to start it again tonight and see if that is still a problem. If so, I'll definitely be swapping in the electric pump first thing next spring. I never did the compression test again, will save that for spring as well.
Getting up to temp definitely made things better. The idle wasn't great, so I have the idle screwed turned in one turn.
I drove it around the block and then to the gas station to put some fuel in. Was so much fun to drive (even at only 35 mph), I'm sad that it's going right into storage. But really was fun to cruise around a little bit (even with the window down in 25 degree weather)
