A little about starting those oldies from someone that rode them for many years. My last chopper was a 1952 H.D. 74 C.I. It was originally a pan head engine that I put a set of Shovelhead juge and heads on. Surprisingly enough , it was almost a bolt on change. The only thing that I had to do was plug one of the oil holes that ran oil up the panhead jugs as the Shovelhead jugs were oiled from an outside line that tapped into the R.H. engine cover. The old Harley engines had a distributor on them and were originally set up with a cable that worked off of the left hand grip to dufus the timing on start up. I eliminated that grip and cable and simply reached down and gave the distributor a slight twist. The over the handle bars thing I guess was possible if you didn't dufus the timing and while I got kicked a bit a couple of times that I didn't dufus the timing , personally I think the over the handlebars stuff is a bit of a wives tale. In all my years of riding , I never saw anyone actually get kicked that hard.
My bike had no choke and if it sat overnight , it required about 4 kickthroughs to prime the engine. After that , even on the coldest days I rode , it always started on the first kick. After the bike had been started once , all it ever took was one kick and I was off and running. I used the same Bendix model carb. on all three bikes I owned and it worked perfectly for 20 years without a rebuild. If I'm not mistaken , the O.P. has a thread about which motorcycle to buy and I have a picture of me and the next to the last version of that bike in it. The only change I made after that pic was taken was to take off that horrible Girder front end and put the old extended narrowed glide front end back on. The girder looked cool but it was the worst handling piece of garbage I ever rode.
Edit: Found the pic. Here it is. The distributor is behind my leg.
