hey, sup camoit , Today i did the cold choke adjustment you said, adjusted the fast idle cam lever to the second step from the manual and screwed the fast idle screw to tighten it down. Then I screwed the SAS 1,2,3 down and backed off 3.5 turns. I read some where that those are stock setting for the carb. I plugged the air hose going to the distributor to to check if the timing is off , then started the motor up and the truck ran with a high idle. Which is normal on a cold start, I waited to for the idle to go down and it never did. The truck warmed up and i adjusted the idle a/f mixture screw by screwing it it 8/16 at a time and waited 10 seconds on every adjustment. I ended up screw the screw almost all the way in, I found that out when i took count to see how many more turns i can get it all the way in(1.5 turn). Guess i had the a/f screw out too much.

After that i adjust the SAS 1(idle control) by backing off until the engine idle lower. Did the timing and found out the crank pulley only has one(white) marking. Can i use this for setting the timing ? Well i hooked up the light and it was way off, so Turn the distributor clockwise towards the motor and the white mark on the crank went to 12degree BTDC (guesstimation). I'm starting to think it's timing now , guess im going to have to buy that equus timing light with the digital rpm display.

The truck idle better but not smooth. It sounds like it has that aftermarket camshaft sound that lopes erratically. I drove it to kragen and picked up the PCV and radiator cap(old cap sounds like it's leaking). I forgot to unplug the vacuum hose that i plugged up to do the timing adjustment, so i parked to the side of the road and pop my hood, then unplugged the screw and plugged the hose back into the distributor and the truck dies. I closed the hood and started the truck back up. While coming to a stop the truck keep dying so i ended up plugging back the vacuum hose. After 30min of driving, it idle high, so i backed off the SAS 1 bout 2.5 turn to get it to idle lower. The truck is still idling a lil high but i can't risk to adjust it lower cause it might die. Everything went cool until it hit 5 o'clock pm. The truck continues dying at 30-45mph. came home and adjust the idle screw a couple turns and left the truck for another day to work on.
