A couple of lessons learned over the past few days:
1. A Sylvania H6024 sealed-beam headlight is the same one as used in our Hondas and you can get them at most auto part stores. If you don't remember the exact model number when you're at the store, tell them you need a headlight for a Jeep CJ-7. It's that bulb.
2. Soaking carb boots in Wintergreen oil really does work. I used about this much oil along with 2 cups of water. I put them in a pan and put them on medium/low heat for about 4 minutes and then removed them onto paper towels. They didn't swell but they were (and still are) pliable and you can work with them.
3. When mounting carbs to the bike, use a ratcheting tie-down strap wrapped around the carbs and the front of the frame. It not only helps to pull them into the carb boots properly, it holds them in place afterwards while you tighten the clamps around the boots.
4. Attach the throttle cables and choke cable to the carburetor rack BEFORE you mount the air box.
5. When mounting the air box, push the box in so that the flexible rubber boots in the air box are mostly aligned at the bottom of the 4 carb holes. Then, lift the air box up and then gently but with some force, push it forward to try and get all 4 boots onto the holes at the same time. Once you get all four of them started, gently pull the box back. Remembering that the flexible rubber boots in the air box move in and out, as you pull the box back, make sure to pull each of those boots so that they're staying on the carb and only the air box is moving back into position to be mounted.
Hope these help someone else. Seems like we learned them the very hard way.
