Hey guys, I need some help please. This is going to be a rather winded post, so please bear with me.
I have a newly acquired '66 Econoline with a 240. I've just replaced the carburetor (holley 1940 with manual choke) with another Holley 1940 only this one has a hot air choke. I suspect this engine was changed because I'm finding an awful lot of '68 - '69 Ford part numbers on it. The exhaust manifold already had a hole in it for the choke tube so I was good to go with the swap.
It was running poorly, the old throttle shaft was leaking gas all over the manifold and every gasket was wet. During the swap, I found quite a few huge vacuum leaks. I'm surprised this thing ever ran at all.
On top of the carb, here's what I've done:
New plugs, wires, cap, rotor, coil, points and condensor. I set the points correctly. The van has a new fuel pump (correct fuel pump with filter housing), new vacuum line from the dizzy to the carb.
I did things is stages.
First, I changed out the carb. It cranked until the float bowl filled and fired. I adjusted the idle/air and idle speed screws and she purred like a kitten.
Hell, the choke even worked and flew open once it heated up. I was tickled to death. I took it for a run around the block and she had great power, no dead spots, I was shocked because it drove like a new van considering I replaced the clutch last week and really hadn't driven it much since.
Before I called it a night, I figured I should let it cool down and adjust the choke because it took just a bit longer to fire up than I thought was necessary. So, several hours later, I went back out to the shop. I adjusted the choke. I turned it lean and rich to make sure the rebuild monkeys had hooked the spring up correctly. It all looked good, so I set it to 1 click toward rich. Checked it using the old "drill bit" method and went to bed.
Then, the next morning, I went out to the shop, gapped my plugs and proceeded to install the tune up parts.
I finished everything and went to start it and nothing. Just cranks then acts like the battery is getting low then picks back up.
I took everything back apart, rechecked my choke setting, rechecked my point gap, made sure I didn't bone the firing order, then pulled the plugs and noticed that my new plugs were fuel fouled. AH-HA! Choke issue.
So, I replaced the plugs with new ones and looked at the choke again. Reset the choke to about where it was from when the rebuilders set it, tried again... Nothing. I pulled #1 plug and got bit verifying that I have bright blue fire.
What am I doing wrong? I know I've got to be missing something. Any help would be greatly appreciated!
1 pull gas line make sure fuel pump pump working and filter not plugged.
2 make sure choke is closing ALL the way mine won't start unless the choke is ALL the way closed
3 see if it now will start
4 if it still won't start check spark again I have had allot of problem with coil the last couple of years
5 will it start with starter fluid
