Always thought these cars were really cool, plus I'm a pontiac fan at heart.

Set the initial timing to 13 degrees today and have the idle mixture screws about 1 3/4 out with 17 inches of vacuum. Running good so far, hopefully I don't foul the plugs right away again. Only have about 4 weeks left and I'll have to put it away for Winter.

That's nice, looks really professional. You must have a fuel gauge hooked up to the back......good idea.

Yesterday I got the carbs back on, took it for a short drive to warm it up and then adjusted my fuel bowl levels. Shut it down and changed the plugs and oil. Today I'll check my initial timing and re-adjust my idle mixture. So far on the first drive, it ran good, started good, idled good.

That looks just like my set up, only you have much better heads :). If its not too much trouble, could you send me a picture of your fuel log set up? I don't really like the way I have mine.

You described my outboards exactly right.

I went to put in a new power valve tonight, I grabbed a hold of the old one in the metering block and it twisted right off by hand. It wasn't tight at all. I looked at the book and they are supposed to be tightened to 120 in./lbs. Could this have been the cause of my plug fouling? Maybe if...

If I remember correctly, it was reading around 6 psi when my gauge was still working. Now my gauge seems to be bad because the needle is bouncing around so much its hard to tell.

He didn't mention if the shifter would actually go through the stock 4 speed hole location. I wonder????

Good point. As long as I have the carbs off, I'll take a look at the accelerator pumps.

Another thing that has me curious is that I really have to adjust my float nut almost all the way down to keep the fuel level at the bottom of the sight plug. I have to crank them down almost to the point of running out of threads.

I have mechanically actuated outboards with replaceable jets. I'll replace the PV and hopefully get the carbs back on this weekend with a new set of plugs and see if I'm still fouling.

Just check the PV using the old school method. It pulled in and seems to be okay.

I have the center carb apart now. I wonder if there is a way to tell if the power valve is bad? I have spare 6.5 and will try putting that in. Since I've checked just about everything else, I'm now wondering if my fuel pump might be putting out too much pressure, thus causing my plug...
