    1984 C10 305 stall at low speeds, loss of power during accel

    Alright so I fixed 2 issues and I found potentially one. Now my engine is idling at about 850rpm in Park and 550 in Drive or Reverse. Is this within normal range for a 305 or would this still be considered high? The first issue I fixed was my rear vacuum break connecting rod didn't seem to be...

    1984 C10 305 stall at low speeds, loss of power during accel

    Ok so quick update: I am still troubleshooting the high idle i did find a small vacuum leak at the carb base plate but from undertightening not overtightening. But my idle is still high between 800-900rpm at normal operating temp. One thing ive noticed is that when i first start it “cold start”...

    1984 C10 305 stall at low speeds, loss of power during accel

    So right now the normal idle speed screw is fully backed off but I still wasnt getting any lower than 900rpm. So thats what made me think vacuum leak. I did kinda want to adjust the mixture screws in till i created a lean condition and then back them off to max vacuum. I have been working with...

    1984 C10 305 stall at low speeds, loss of power during accel

    Ok i feel that. Knowing its probably not the issue but at least get it out of the way and one less thing to worry about especially if any other issues arise in the near future. Honestly im just being lazy and didnt wanna drop the tank since i read it could be a pain. Thats crazy about the carb...

    1984 C10 305 stall at low speeds, loss of power during accel

    You think bad gas could cause a high idle issue? I do plan to eventually drop the tank clean and replace the old gas, but just hasnt been high on my list.

    1984 C10 305 stall at low speeds, loss of power during accel

    I've topped off the gas with new gas but have not drained/ cleaned the tank and then replaced the fuel. I am using a basic duralast in-line fuel filter it is not clear. But the truck is running mostly smooth now except for the slightly high idle which I can't seem to figure out.

    1984 C10 305 stall at low speeds, loss of power during accel

    I do believe I have an intact esc distributor. I have not tried the fix you suggested just yet. But rebuilding the carb did seem to fix most of my issues along with the small vacuum leak repair. What exactly would bypassing the esc do? I would like to know just incase it becomes something I have...

    1984 C10 305 stall at low speeds, loss of power during accel

    Yea it took me forever to go through the carb rebuild myself I definitely give credit to the guys that do it cause i do not have the patience for that. Had to piece through 3 different sets of tutorials and the provided instructions on the rebuild kit and still felt uneasy with fingers crossed...

    1984 C10 305 stall at low speeds, loss of power during accel

    Your and my thought process was very similar on this and I did go back check through the distributor, plugs, wires, and connectors, I couldn't find the vacuum leak originally with the carb cleaner but I'm sure that would've probably helped a little. The carb rebuild ended up showing the most...

    1984 C10 305 stall at low speeds, loss of power during accel

    Yea I still don't know what caused it and I thought it was very weird that after that first bump the truck then had low speed stalling issues. Still don't know what caused that but as for now the vehicle no longer bogs down at idle and can be smoothly rev-ed without issues. I have yet to take it...

    1984 C10 305 stall at low speeds, loss of power during accel

    Ok coming back to this thread... Ok so coming back to this thread again because I moved forward but still not exactly where I need to be. Thank you all for the replies I didn't check it out too much because I am impatient and went to go see if I knew anyone who had experience with this engine...
