Not sidedraft, just the single Weber conversion. Choking...well it won't start without choking it. But lately it won't start anyway without major time and trouble, taking plugs out and stuff. And today it didn't start at all. The starting fluid, I only did that one time, and I'm not sure if that was why it started or not, because I did other things too. I'm going to look at it now, and I will take a wire to act as temporary points to try and get a strong spark out of the coil. And maybe take a look at the wire that's supposed to hook onto the starter (and go to where?) cause often it tries to fire just when I let go of the starter button.

Thank you for responding. Any other ideas would be welcome.
