Carb shooting mist..no start

68 390....cranked over and over...roughly 10 seconds it will shoot a mist thru carb...sometimes 15 seconds..very intermittently. I sprayed carb cleaner to help start. Still no luck. I'm still having throttle linkage issues. Pedal goes straight to the floor and doesnt go back up without picking up pedal I disconnected the linkage going to throttle and the carb opens and closes just fine.

I also set timing with timing light. While cranking the motor.

I removed spark plug one cylinder 1 and checked spark...great spark. But it did shoot a mist out of the cylinder while I was standing there....


She never did run....


New fuel pump..ignition starter...timing gear/chain. Cap and rotor..plugs and wires. Rebuilt carb..

I thought for sure it wasnt But hell at this point anything is possible..I made sure number 1 cylinder was at tdc and rotor point to roughly 1 o'clock position. Which would be spark plug 1 correct?

When I rebuilt carb I didnt set bowl level. I'm not sure what that even means. I just replaced parts that came in the kit. Maybe shes getting to much fuel? I'm not sure

Being TDC is right, but remember you have 2 TDC Pull plug 1 and crank engine over with your thumb on the hole. When you hit TDC for compression, you'll feel it. Make sure coil wire is off! Then pull distributor cap and see where the rotor is. Is it at #1? Or is it opposite? If opposite, you'll need to pull the distributor and rotate the rotor and set it to #1. Then see if you get any reaction.
As for carb cleaner, it won't help start an engine. But starting fluid will.

I'm 99.99 percent sure it's right...number 1 was up all way...rotor was pointing to 1oclock position on dist cap. I remember checking and rechecking. I just want to be sure that number one plug on the dist cap is 1oclock position if your standing directly in front of the engine

Don't know. #1 should be printed on the cap. Take white out or a marker and mark the distributor on the side where the #1 is at on the cap. Then pull cap off and see where rotor aims. Make sure your at TDC.

My cap isn't numbered. But I rotated the engine with cap off. And lined it all up. The rotor points right about the 1oclock position

Your carb not closing is another issue. Do you have a return spring on it other than the one on the throttle shaft of the carb? Where the gas pedal shaft comes through the firewall is a bushing that the shaft rotates inside of. Possibly binding the shaft.

I have found 2 springs but not hooked up..not sure where they go. When I got this truck it was apart around the carb.

They usually only number the #1 pin.
