Why are the cam lobes all wrong in the directions? I mean on the ome bank, the exhaust and intake valves all open at the same time.

I couldn't figure that out either. I don't find it listed anywhere why. I ended up swapping around the cam lobes to match the other side. I appears to be operating correct with way it functions & the spark plug firing. It should have been noted someplace why the cam shaft was different on that side. The only thing I can figure is maybe they are trying to show the way 4 valves per cylinder operate (even though there are only 2).

What are the dimensions when built?

Height 8.5” Depth 8” Length 12”

What kind of tools are needed for assembly?

Generally all you will need is a small precision screwdriver. They send one in the package,however if you a set of precision stew drivers you're good to go.

Anyone know how to reach the vendor (Playz website just sends you to Amazon) I have a defective motor.

If you click on the product you ordered from Amazon you can choose actions and one is to message the actual product store and then you can write a message and Amazon passes it on. I just had to do that for a damaged product return.
