I have a O & R small engine that I believe is a Weed/Leaf blower. I would like to identify this engine and believe it has possibilities for a plane engine. It appeares to be apprx 18cc. I have attached Pics for U to help. Maybe a website someone could direct me too. It needs a carb. It was manufactured by O & R engines Inc. out of LA, Ca. Have been all over the website searching however am unable to locate any info on it. Tks.

try the engine conversion forum. but i must confess that it looks like it might to be too heavy for a conversion engine. the newer weedies usually have pretty light crank cases. the engines before that were made of heavier materials.

I should have mentioned that the total engine height will be apprx 4" tall and 3.5" long when stripped of the access metal. The pictures dipict a large engine. I will check your information for results thanks.

Usually 31cc is the minimum engine displacement for a gasser to fly. Ryobi makes a good one and there is tons of information on converting for flying.

Cary: Thanks for the info however I have been converting Weedwackers to to RC plane engines for years and yes Ryoby makes one of the best engines and especially when you can strip one of there weed eaters in 30 minutes and have it mounted in less than an hour. I have scratch built a high wing plane that had a 72" WS and it weighed 17 lbs and flew it with a 18cc poulin. That was before I got into the ryobi's. Ryobi is also the same company that makes the Zenoah Kamatzu G-23 and the G-26. It is the same engine found in weed wackers. The only differance is the way they mount the Carb. If you want to see what one of my engines looks like, U can go to the ads and look for Zenoah G-23. I have 3 of them for sale ready to mount on a plane. I will have 3 G-26's on RCU tomorrow. The reason that I had to inquire about the O & R is that I have never seen one this small and am trying to ID it for a smaller plane. I think it is a 18cc leaf blower. I plan on pulling the head and doing some calibrations to see what CC irt really is. I only need the carb for it however having said that, I think I have some Glow carbs that may work?????????. The only problem with the 31CC weedwackers is the rear Carb. It is a reed valve set up and the carb would sit back into the Fuse and would be tough to get at for adjustment. I haven't been out looking at the Ryobi market for a couple of years and maybe they have rectified that problem with a standard weedwacker. Also Ryobi makes a 28cc side mount carb that is on a weed blower. Stay in touch and agian thanks for the info and it is well taken.
