OK, I have 4 engines and they are all different and I payed dirt for them, but now I need to figure out what I got.
The first is a converted something, it has a Zama carb # p5-02b and on the head it has the number 530 what looks to be a backward "C" or a 0 (its on a seam) 2876c. The flywheel has been shaved already and the number on it is 2067000PW
Here is a pic...
The second one with the green backplate has a walbro carb #wa207a with a number on the head, 028680 and a phelon flywheel. it has a single ring.
