318 Engine stumble
Ok, lets do this intelligently. Is this something it just started? Has it been running well and then started messing up? Or has it always run this way? If not, when did it start? Think about it. After getting gas somewhere? After a rainstorm? Lets not change anything yet until you give a little more info.
I've never much run it. Let it sit for a really long time.
Came back and replaced the gas tank
Put a Holley 600 vacuum secondary....on a streetmaster intake with a 1" spacer as the streetmaster is so low.
The floats were checked but I will check again.
Points distributor
On the carburetor.....the butterfly's were open due to a screw under the carb base plate......I adjusted them closed. Not too tight. However...was unsure of the formal procedure on what to do with them....so I guessed.
Replaced all vac hoses
It's almost like lack of gas but that's a guess
Checked the plugs and set the timing to 8° after not finding an obvious vac leak.
Once the vac leak was fixed I adjusted the carb mix to 19" vacuum. Used a vacuum gauge to set the mixture.
Then set timing to 8° and then the idle speed to 750rpm
The car now idles fine.....
So I changed the carb basically....how it ran before that I have no idea.
It does it all the time. The gas comes from the same place but it's at least clean and not bad gas. It is 87 octane
Plugs are gapped to 35
At idle....the timing mark stays steady.
All other parts are original to the engine. I have no idea what shape anything is in.
