Yes, float height can cause it to run rich. The reason the choke isn't helping it start is because its already rich to begin with.Should I yank the plugs out clean them and see if she’ll run?
Edit: could float height cause it to run too rich? I never changed float height from what my buddy had it at and I highly doubt he ever set it.
Yes, any blown out vacuum device can be a vacuum leak. You should be setting initial timing with the vacuum advance disconnected and plugged on the carb side anyways. I would highly recommend the second you get the thing to start and idle below 1000rpm, you properly set the initial timing to 4-8 degrees BTDC and then not touch it again. You have so many moving targets on this engine that it becomes really hard to troubleshoot anything. Set one thing properly and then leave it alone. Move on to troubleshooting and setting the next thing properly and then lock it down and move on.Could a non functional vacuum advance cause a vacuum leak? Or would it just be plugging vacuum? It’s now pouring rain again I can’t do anything right now it sucked enough changing plugs in the rain but it’s really coming down now
The end with the 90 goes on the cap. They are usually labeled and are different types of connectors. You can definitely just disconnect and plug the vacuum advance and it should run fine.Also are spark plug wires directional? I noticed that each end is different one is kind of softer and squishy and one end is more firm but neither end is labeled as plug or distributor.
