Ok, so I got everything put together, new bumper, new diff cup, new dogbone, new air filter, new fuel lines and new radio.


Filled the tank up about half way and it would not fill the carb bulb. I took off the gas cap and could see bubbles when I depressed the bulb so I know it was connected. Filled it all the way and it filled it up. Why did this happen? I ran it half full from the start before. Do I possibly have a leak somewhere? Maybe return line is too far into the tank?


So after I got fuel, closed the choke and pulled the starter twice, opened it and pulled 2 more times, it fired then died. Pulled it about 2" more times, took a break. Closed the choke then pulled 2 more times, opened it and after 5 pulls it fired. Don't know what happened there either.


High needle is 1 1/2 out. Low is 1 1/4 out. It bigs when I give it throttle. Turned low in at 1/16 increments and is still bogging. I don't want to go too lean. But after it gets past bogging it races, then bogs again to where the wheels stop.


How lean is too lean for these engines? I know each vehicle is different t, but ballpark, where should these needles end up?


Just item 1,436 on today's issue list. Please help???? :)
 
You don't by any chance have your fuel lines crossed; And your pulse hole and gasket are lined up on your carb ok?
 
I'm pretty sure the lines aren't crossed. Filter line to top of carb, vent to the bottom. What is a pulse hole? When I installed the new filter, I used the original gasket from the carb to the motor and the new o ring that came with the velocity stack to the carb.
 
He is referring to the gasket between the carb and manifold and that is where you find the holes that can't be blocked. Does it idle ok ?? Try richening the hsn
 
Idles high now. Didn't before I reset the needles. I did not touch the idle screw either. I will check the gasket. It's very possible that I blocked that hole. Would it do what I am explaining if I did?
 
The pulse hole helps to get your fuel to the engine from the carb. It gets the pressure from the engine witch help feed your fuel. (In a short explanation way of putting it) so yes if blocked it can create problems.
