Default Identify this engine and problem with starting

An old friend passed away and left me with some models. One of them is a Seagull Yak that has a side mount carb on a engine that I can't identify. I know pictures would be best but I'm unable to provide that at this time.

The engine appears to be about 20 to 26cc in size. The number 13 is embossed on the front of the cylinder bass. The spark plug is a Champion RDJ8J. The carb (side mounted) is a Walbro WA197A. The ignition system appears to have two primary components, one a cylinder like component about two inches long and the diameter of a quarter. The other looks like a small Visine bottle that is connected to a 4.8 battery pack. The name Ridge Machine can be seen on the side of the component. A lead from the first component goes to the bottle like component and a lead from the bottle goes to and disappears inside the engine case.

I attempted to start this engine with no luck. I put in a freshly charged battery pack. I removed the carb and replaced the gaskets and diaphragms with a Walbro K10 WAT kit. The metering valve worked freely up and down so I did not replace it. The filter screen was clean. I removed both HS and LS needles to inspect. They looked good. I set them both to 1 1/2 turns out. I made sure the impulse hole lined up with the gasket and the hole to the carb. This carb does not have a choke so I simply covered the intake with my thumb to see if it would draw fuel. It didn't draw hardly at all by hand flipping the prop but did draw strong when an electric starter was used.

I'm pretty sure the ignition works because when I pulled the plug and held it against the side of the case, I felt the shock as I rotated the prop with the ignition on. I did not see a spark at the plug gap but my eyesight is poor and that may be the reason.

I replaced the fuel tank and all new lines.

I can't get so much as a pop out of it whether I flip by hand or use an electric starter. Any Thoughts?

Thanks Indiomike
