Re: Newbie thinking about diving into a '65 GMC 1000
Lot has gone on that I have missed out on! Glad ya got it going, I'll check out the video when I get back from work. haha Glad your also keeping it stock. As a gmc owner myself it's pretty rare to see them left alone and not done like the rest of their chevy brothers. Here's a neat book I found on Ebay if your interested. Planning on getting it really soon:

Re: Newbie thinking about diving into a '65 GMC 1000
Did you give it any type of tune up? Plugs, wires, points? What's your timing set at? Do you have a timing light?

Re: Newbie thinking about diving into a '65 GMC 1000
I've checked the plugs, wires, and points and they all looked good, but I did not check the gaps or point openings because I didn't have a feeler gauge with me. Haven't checked the timing yet but my manual says to set it to 4 degrees BUDC. I do not own a timing light (yet).

Re: Newbie thinking about diving into a '65 GMC 1000
Even though the plugs, wires and points look good, it wouldn't hurt to replace then in doing a good old tune up. The points , condenser, cap, rotor, plugs and wires, as well as a fuel filter plus a oil and filter change. You might be surprised what a difference those things will make.....when installed correctly.

Re: Newbie thinking about diving into a '65 GMC 1000
Sounds like the accelerator pump is not working " if I don't go nice and smooth, she dies out."

Re: Newbie thinking about diving into a '65 GMC 1000
NOT sure where the springs hook on a 6 but you can check the accelerator pump WITH engine OFF ..look down the inside of carb work the linkage with your hand to full throttle and hold it there for a second and there should be a stream of gas spray into carb... THE other thing that will make them stumble on take off is the vacuum advance on the distributor with CAP off pull vacuum hose off carb stick it in your mouth (if you don't have a hand pump) suck on it and watch the rotor it should move once it moves place your tongue over the end of hose to hold vacuum (very tasty LOL) if it don't stay or does not move you need a new vacuum advance there is also a mechanical advance in the distributor to

Re: Newbie thinking about diving into a '65 GMC 1000
Here is a carb accelerator pump test watch first 18 sec. https://www.youtube.com/watch?v=I319vj9ktSwa ... I had a brain fart when i said the rotor would move.... the vacuum advance only moves the point plate ...The mechanical advance moves the rotor here is video on vacuum https://www.youtube.com/watch?v=j3TdDGzo_Ig And here is one on mechanical https://www.youtube.com/watch?v=oxgmCXeIVZo

Re: Newbie thinking about diving into a '65 GMC 1000
The vacuum advance checks out when I suck on the tube from the carb to the distributor, and the accelerator pump does in fact squirt a bit of fuel into the carb chamber. It is not quite a jet stream like shown in the video, more like a dribble. Not sure if that matters.

Re: Newbie thinking about diving into a '65 GMC 1000
I agree. I pointed out that the one in the lower right is likely in the proper position to help close the throttle linkage. That might be the only one he needs.

I would think that if its NOT a good stream then you are not getting the fuel you need upon acceleration "the one in the lower right is likely in the proper position to help close the throttle linkage. That might be the only one he needs" AGREE 100% Marshy |

I bought this carb off of eBay as remanufactured so I think I might file a claim...

Re: Newbie thinking about diving into a '65 GMC 1000
This is very important. Crud in tank will mess up a constant flow of fuel. Pull the tank and have it cleaned out and sealed. Your engine appears to be original. GMC engines were painted red from factory. GMC engine codes are not the same as Chevy. Very little is known about GMC engine codes, info is just not out there.
