Yes, I have a multimeter, and I have checked to make sure my battery has adequate voltage.

Of course the vacuum line is connected. And as I said, I drained the carbs. Then when I tried to start it again, I turned the throttle enough to get fuel into the carbs. Then when I removed the carbs, I had to drain them again. So there's no problem with fuel getting into the carbs.
Well then, if you have gas in the floatbowls you either have issues with the carb or you aren't getting spark.

Are you giving me attitude here?

Turning the throttle has nothing to do with getting gas to the carbs - the vacuum from cranking/running opens the diaphragm in the petcock and allows fuel to flow. That's why I was asking you to confirm fuel in the floatbowls.

You wouldn't be the first to forget to connect the vacuum line back to the petcock.
