This afternoon I installed the Indigo PCV kit on my late model A4. I got the Indigo kit instead of the one from Moyer because I didn't need the flame arrestor, and the Indigo kit comes without one.
It was very simple to put on -- in the "easy" category if you're at all handy with tools. I also put on the extended, knurled idle mixture adjustment screw and the adjustable main jet. The main jet adjustment was the trickiest part of all -- I did as the instructions said and opened it up 1 1/2 turns from the seated position, but when I tried to start the engine it wouldn't keep running.
At first I thought it was the fuel line not primed up after having the carb off, but I pumped that up with the bulb pump so I knew that wasn't the problem. Then I thought maybe the fuel pump was acting up, so I took the line off the carb to see how it was doing, and it was fine too.
I knew the problem was fuel starvation, and the only thing left in that line was the adjustable jet, so I cranked it open another whole turn, to 3 turns from the seated postion. That let the engine keep running, though it seemed to prefer having the choke partially closed, so I kept opening up the adjustable jet a little at a time, waiting a couple of minutes between changes to let the engine stabilize, and I finally got the best results somewhere around 4 1/2 turns. (I lost track from not paying close attention to how many times I went through the process.)
It also took forever for the engine to warm up with this cold Rock Creek water, but I finally got it up to 150 deg. and made my final main jet adjustment, getting 2100 rpm out of her in gear tied to the dock. Then I took her out of gear and eased her down to as low as she'd go without stalling and started adjusting the idle mixture.
I started at an idle around 1200 rpm, and enriched the mixture by turning the new idle mixture screw clockwise (love that extended, knurled screw -- it makes idle setting a tool-free exercise!) until the idle increased a bit, then adjusted the idle speed screw down to abut 1000 rpm and made another clockwise adjustment, repeated as necessary until she held a nice steady idle at 800 rpm. Sounded great. Claimed victory.
Then I thought, well, I'll just finish up that last bit of wiring in the house panel and... Oh, dear Lord what is that? Another of the PO's wiring abortions, this time with the steaming light (which he had labeled as the "forward anchor light") and the running lights wires twisted together way back there, with a bit of solder on them and not even any electrical tape on the positive leads. How those lights ever worked I don't know.
So there's my project for this Saturday: getting the last bit of wiring taken care of so that I can start looking at the actual sailing bits of my boat.
Can't wait.
