I'm not trying to be mean, but...
To a seasoned mechanic, a "rich stumble, a lean stumble and an ignition stumble" all are easly told apart by how the act. All fall under the heading of rough running. It is hard to impossible to explain the differences over the internet. Each can have many causes or it can be a combination of more than one.
Rough running is just to vague to give meaningful help.

I guess to battery would be a better ground. if the ground doesn't solve the issue which I doubt it will I will check my vacuum and advance first then for fuel then go back to timing. im pretty sure I got it pretty close. but as previously mentioned I have no idea really what I was doing. I followed previous forum posts best I could, but ive never done this before and had no one to watch me if I screwed up.
what would I be seeing as far as vacuum pressures? I don't have a way to check this or even know how but I can buy the proper tool if necessary.
I got a new carburetor and have adjusted just the idle. its a Daytona universal 1901. again I don't know what im doing so keep it simple if I missed something. the company I bought it from fired it up before they shipped to Canada so I didn't think I would have to adjust anything.


Do you have the original carburetor you could bolt on for testing?
