I picked up what I believe to be an O&R Compact III Chicken power bicycle engine. It was seized up when I bought it. I have since blasted and free'd it up. It will certainly need a lot of love. However what I am curious about is the recoil housing, and the manifold/muffler on this engine. All of the Orline/Chicken power bicycle engines I have seen had the common 'teardrop' O&R blower shroud. This one has the later boxy blower shroud. This one also has an odd exhaust manifold with a threaded end. This is the first I have seen a threaded exhaust manifold on an O&R. Is this engine just an odd combination of parts? There are no numbers on the engine anywhere, and sadly the one sheet metal shroud that would have had some stamped information is missing. There are no numbers stamped on the flats of the crankcase.

For your amusement is the rare 6 port O&R engine! This engine was put away "running", as I am sure most are! This little O&R must have been dug out of a lake bed. The muffler was completely packed full of mud. I bead blasted the engine and submerged it in my heated ultrasonic cleaner for three days. I gave the cylinder a wiggle with my O&R cylinder removal tool, and snap, the connecting rod blew in half. With the cylinder separated from the crankcase I re-blasted the engine this time getting under the piston, and into the crankcase. The crankcase free'd up within an hours time in the ultrasonic. The piston was a job the grease gun fought with. I am surprised to say that this little casting can actually take 5,000psi of force, as the bypass on the pump hit a few times as heat was applied. The little piston finally came out, and it was rusted and corroded all over. It turns out that the mud in the muffler eat through the cast iron liner into the cylinder. So much for trying to save the cylinder! This one is a goner. I will have to put a donor piston/cylinder/rod in this one when I go about replacing all of the needle bearings. I thought you guys would like to see the pictures even though the situation isnt the greatest. The pump has been loosely reassembled and now has spark, so that is a good thing! Chris

Thanks! I appreciate it. I think mine was run on 50:1 or straight gas at some time. It is on an insecticide sprayer so it is certainly worth fixing! I hope to pull the cylinder soon and see how the bore looks. It appears to be a 'chrome' plated bore which I was surprised at. I was hoping it would have had a cast iron bore like the little compact engines. Chris

Thanks! I was really scratching my head on this one, as I have a lovely Orline chicken power in my collection, and there are a LOT of small differences between these two units. I would love to complete this one, as I want to run two of them on my bicycle at least once! Also as a side note, I forgot to mention. There is no primer on the AEP bicycle engine. This carburetor was on this engine when I bought it, but there were a few other busted up carbs in a bucket of loose parts with it, and I wasnt sure which it had. Would this have had a primer carburetor? Also, if anyone has a type number for this AEP bicycle engine, can you please share it. I will need to hunt down the right parts for it at some point. Chris

Next Saturday is a smaller get together up in Maine so figured I'd bring up some of the stuff that doesn't go to the big shows. They haven't seen the light of day in a LONG time so it'll be nice for people to see them. They're too small and expensive to leave unattended at the big shows although I have never heard of any stealing of anything at any of them. Just a small sample and will probably bring about 20-25 tools or so depending on available time to get them out.
