I Googled Ridge Machine and that led to D&B which identifies the ignition as a Reismuth. I don't know if D&B actually produces engines. If you look next to the number 13 on the second photo it looks like the letter E surrounded in a square box. Could that identify the motor as an Echo?

Well, I completely dismantled the carb and sprayed every opening with carb cleaner. Then I re-assembled will all new parts from a K10WAT overhaul kit. The dang engine would not draw fuel. I happened to have a Zenoah G23 which has the same carb, a Walbro WA 197A. I swapped carbs and got an instant draw of fuel. So, something is amiss with the first carb. I made sure the fuel draw side had fuel in it before screwing down the 4 screws. I was also able to confirm a spark from the ignition by closing the garage door so it was dark enough to see the spark with the plug held against the side of the case. I'm not sure what I'll do next. I found only one vender who sells a WA 197A but it was almost $80.00 and no doubt over that allowing for shipping. Anybody have any suggestions as to a substitute carb that is more ready available?

Thanks Mike
