I need help settinig the timing

If someone brought me something like that to fix, I think I would little drop my pants, dump in the gears and give it back to them.
vintage 1920-1935 i would say. Looks pretty standard for a rotary configuration. Whats your problem.

Nah, that's an awesome picture and even better caption. I just know what the gear train on a slide sleeve radial engine looks like.
That one is a great picture of the opened gear drive assembly on a bristol hercules 14 cylinder.

Nah, it's not like that. Just a history/enginnering buff. I was really impressed with those engines. They were 2,300 cubic inches and put out like 1,200 hp. Not too bad for the 1940's.
I actually developed what I found out later was a double sleeve slide cylinder as an engineering project. I didn't know that someone had made that but I determined that the geardrive pictured would end up being the downfall to making one that was simpler than a pushrod poppet valve engine. The double sleeve has less moving parts (except for the gear drive) than a rockerarm poppet assembly and allows for adjusting overlap and duration independently while never allowing for an inference piston on valve at any timing setting.

Woah thats cool as heck! But talk about a headache.
Looked around youtube for more vids of those, really cool stuff!
heres one running.
And heres a lawnmower sleeve valve engine.

kgibson, I started thinking about the ways to combine the advantages of a 2 stroke and a 4 stroke. I drew a double sleeve cylinder 4 stroke engine out and was planning stages when someone brought to my attention it's already been made. I didn't get the idea from somewhere else, simply arrived at the conclusion that a 4 stroke engine with 2 stroke ports would be very efficient. Turns out it was!
Instead of a regular 4 stroke engine where valves will either hit each other or the piston, each sleeve port can be made differently to adjust the timing independent of the other ports.
