Bucc,
I’ll find a nice QD-14 and QD-15 someday. I like the style of the early QDs and a twist grip throttle with the front shift makes for a really nice motor if you ask me. The ’53 is indeed the first year of the twist grip throttle. The ’54 is the first year for the up and off cowl and the second and final year for the seahorse cast into the tower.
My QD-13 had about 72psi top and bottom when I started out with it. It seemed a bit low, but OK. It runs great and has good power. I have not re-checked it since putting a few hours of run time on it. Your ’53 could just have partially stuck rings or something that may free up with some use and improve the compression. I’m sure it’s been sitting a while and it’s dry too. It will run at thise numbers. I’d try it and see how it turns out. I don’t have the parts manual.
