You say it bogs with no black smoke after a couple seconds after stomping on it. If you push to WOT a little slower than stomping on it and it runs smooth through the point where it bogged, then that is a pretty sure indication that the pump shot is running out too quickly as mentioned.
That O2 sensor would really help here.

And +1 on the sweet Fairlane. A set of CJ valve covers would really look sharp on that thing! Hey, it's only money  ;)

Checked the float levels again today in sunlight and they are both fine. Terrorized the neighborhood Took a couple of laps around the block today after switching the cams to position #2 and it's a world better. Looks like I'm just gonna have to tweak by the seat of my pants till I get a wideband sensor installed. And I gotta say... the new carb is making this old girl like a whole different ride entirely. I simply cannot believe the difference. The throttle response is so much faster and fluid now. I'm gonna have to figure out a way to keep the fan belt from screaming every time I goose the throttle.  Gotta say, that's a problem I don't mind having right this second. ;D

Font cam is black and the rear is peach colored. The front shooter is a .031 and the rear is a .025. Seeing as the #2 position on the cam cured most of the bog, should I be looking into smaller shooters?

CJ valve covers.. only if the stock article start to leak. I'm not ashamed to admit I used a bit of Right Stuff on both sides to get those guys to seal up. I'm so far over budget on my little "header" upgrade from last year I'm having a hard time lookin' my wife in the eye, good thing she really loves me.   ::)

Now that's funny  :)

Smaller shooters will give you a longer squirt time and should help, provided it doesn't put you back in to a lean bog. If it does, you may have to look at the bigger 50cc pump to get the extra capacity along with the correct shooter to keep you out of the bog. It can be somewhat time consuming to get it all right, but it's always a great excuse to terrorize the neighborhood take a couple of hot laps.

"Header upgrade".. I say that to myself a lot nowadays. This entire motor refresh started from a cracked exhaust manifold that I noticed when I was getting ready to replace the gaskets on each side of the stock heat riser. I still have the $2 worth of gaskets in the glove box. I take them out and look at em' every time I start feeling the need to "fix" something.. it reminds me of the thousands in excess I just spent for my "header upgrade". :P

So how far down in shooter size should I start at? Most carbs I've read about seem to use .025 as about the smallest shooter. Should I start with another .025 for the primary? I ran around for a few hours this afternoon and just the change in the cam screw position really did clean things up a lot. When I get a chance I will definitely be getting a bung for a wide-band sensor installed. Probably get it done when I have the chrome tips put on the exhaust. I might wait till I get it installed before swapping out any more carb parts. It's not running bad now at all and I prefer to not stab about in the dark if at all possible. That sensor really eliminates the guesswork.

Anyone have suggestions on how to stop a fan belt from squealing? Aside from electric fans and water pump that is. Belt is pretty tight. I might try scuffing the pulley with some sandpaper and getting a new belt to see if it helps. Sounds pretty awful when I roll on the throttle.

A double pulley on the alternator and water pump will help.  Next time you feel the need for spending thousands of dollars a minor upgrade, you might think about including the pulleys  ;D

Most times the squeel is caused by a belt that is old enough to harden or has been "burned" on the outer rub areas and is hardened enough not to get a good grip. Usually a new belt will cure it. I like the double pulley set-up that Jay mentioned and use them.

I know it's more money, but a Holley pump tuning kit is a "must have" for carb tuning. Investing in a pump cam kit and a couple squirter sizes above and below where you're at now will allow you to play with the combo to see what the engine wants and needs. Every engine is different, so just start with what you have and experiment to see what it likes.

Water pump already has a double pulley as it was a stock AC and PS car. Wonder how hard it would be to locate a double pulley for the alternator. Then again with my luck I'll end up needing to replace the entire harness, every bulb and fuse.. maybe I'll take that $2 worth of gaskets out of the glove box for a refresher.  ;D

Here you go with  a two groove pulley.

^^^ Thanks! I picked up a new Gates belt last night, if that does not cure it I know where my next stop is now.  ;)

Best $13 I've spent so far this month.. I got mine on Ebay.



Had to use "Master pro" belts as the Gates and Goodyear belts ride too high in the V and don't make enough contact. But no more sqwealing belts when I roll on the throttle!!

 :D

Last update nearly 3 years ago... guess it's time. Car has since had a new interior installed, a new set of 17" wheels (9" in rear.. 7" up front) and I just got it back from paint yesterday. 5 coats of single stage candle apple red.... just happens to be the stock color.




Looks a shade lighter in direct sunlight.



Just in time for the summer driving season! :)
