wall 4 valve timing.

[bluejets]

You could put a degree wheel on the crankshaft and watch the valve lifters or the valves themselves and very quickly determine if crank / cam timing is correct...

Just a thought

Yes, as suggested in #16.

Below is one of the many charts I draw up to grind my cams.
This particular one is for a flat crank 4 cylinder. ( might help you out...)

What a happening ! I just 2 days ago took photos of the blueprints, I have for a Elmer Wall 4 cylinder inline flat head engine. I also own one, but not the same as the prints. The main difference is the distributor ! My engine is on YouTube, running. Now I have a question. My engine has a full circle crank. Was that a special crank because the prints show a crank with no counter weights ? Thanks in advance

I believe you are correct that it was special, mine is flat. you had helped me with mine a few years back before when my account name was matterest. My engine does not run as well as yours tho

My engine when I got it did not have any compression at all. I took the pan off & spent much time cleaning it out. Used a tooth brush even. Rinsed the insides out with clean fuel & blew out that with compressed air. I lubed the internal parts & placed the pan & spark plugs back together. Then I added Klotz 2 cycle lube to the correct level. Then re-built a ignition system. The engine then did have enough compression too start. The more I ran it & tuned it the compression got higher & higher. I use Klotz oil in all my small engines. They all gained more compression. The good thing is there is no carbon build up, as I have been running one engine at shows for 10 years. Cleaned the spark plug only once. My Kavan 50 twin the same way !!!!

Which klotz oil is it the type you mix with the gas?
Also how do you keep oil from leaking out of the crankcase mine leaks like a sieve

 

[Capt,n John]

I use Klotz 100% pure synthetic Techniplate oil. SAE 20W Grade 60. It has very good body to it. Where does your engine leak oil? Got 6 Quarts of it....should last as long as I live !

 

[whitehouse260]

I'm really not sure where it's leaking I know it comes out the gear cover but that's my fault( I need to make an oring to seal the shaft, I screwed up the original casting and 3d printed a new one with a modification to removel the miter gears.)
I think it is leaking out the bottom part of the crankcase I guess that would be the oil pan?

 

[Capt,n John]

My engine has a small amount of oil that seeps near each valve lifter...not a real problem at all. I just wipe it off after I run it for the day I show it. I did build a advance rod that connects the throttle lever to the distributor arm. That really works sweet ! I sometime may place a full electronic ignition on it. Not right away, I had surgery on my left hand & it is just workable more than 3 years later...but not much feeling in it.
