Checked the timing this weekend. When I put the timing light on the balancer, I couldn't even find the timing mark. Played with it until it came into view. It was advanced way too far. That explains the high idle speed, hard to start, gas smell and poor gas mileage. Although 10 BTDC was recommended, the truck seemed to run better at 8 degrees BTDC.
Don't get me wrong, its not fixed completely (choke is still an issue). Not sure how well the truck will start when it's cold again. After warming up and fixing the timing, the truck started very well. I can manually shut the carburetor and start it later when it's cold...I guess we'll see. I'll report back later.
-If you rebuild a carb, will that fix the choke?
-What does it cost to rebuild a carb? Either myself or a pro
-I currently have a 2BB carb so wonder if the cost is high enough to upgrade to a 4BB carb and intake? I know I want to but I'm too cheap ;-)
-Even when warm, the truck had a slight hesitation when I hit the throttle. I gapped the spark plugs at .40, maybe .45 is better?
thanks for all your advice.
