Nice job! Can't wait to see it done Did Joe have a throttle for you or do you need the one I showed apic of??

Nice find! What is that ring thingy under the spark plug?

It seems you guys in Europe collect different stuff than we do over here so I was curious what something like this would sell for over there. Runs and cuts For sale locally for $120

Have only seen 2 show up for sale but that doesn't mean I missed some. They come mostly from Chicken Power engines. The one in the pic came from an Orline hedge trimmer. You can try sending a PM to member Webhead and see if he has one for sale. As a last resort, I can probably sell the one in the pic even though I need it for a Chicken Power. I'll never use it to mount on a bicycle but I like to keep my engine stuff complete. I'll let it go if I have to because I'll probably come across another one before you do. It will need a longer conduit and cable for use on a bicycle.

Not sure why this posted in this thread but removing the ethanol also lowers the octane. Best to start with high octane fuel and add an octane booster BUT, make sure you research the booster because most are made with some form of alcohol, so adding it back into the fuel doesn't make any sense. You will need to find a petroleum based octane booster. I know Lucas makes one but I'm sure there are others. Funny, I just did some research into this exact thing a couple days ago. I sent some questions into a site which explains most of this but didn't have anything concerning the removal of ethanol with water to use the fuel. Hopefully they will answer back

The O&R throttle setup on these carbs are a little different for hooking up a throttle cable in the sense that the cable does not pull the butterfly open, but it needs to push the butterfly closed to get to the idle position. Most twist throttles will have a return spring built into them. here's a pic of an O&R throttle. Not sure where to get the small conduit but maybe a bicycle shop will have it. Where about in Jersey are you? Grew up in the Cherry Hill area across the bridges from Philly.

I use regular 87 octane and have no available stations that sell non ethanol gasoline. I only use my engines for display and don't really work them so it doesn't really matter to me. Yes the ethanol will eventually turn the diaphragm into cardboard so if you plan to use the engine I'd suggest paying the money for a can of Trufuel. They sell ethanol free fuel in expensive cans at mower shops and Home Depot. The original specs of the engines suggest using 30w oil but oil technology has changed so much over the years. Yes, i use synthetic oil Let me know if you need any pics of the pawls if it isn't apparent what is binding them up

The pawls should have small flat springs which close them for starting and then the centrifugal force of the flywheel spinning when it starts should force them out to stay disengaged. Sounds like you may have something binding them up in there. I use normal air cooled 2 stroke oil mixed at 32:1

Use your best judgement for torque on that screw. I assume you are going to use a jack shaft to get your correct ratios.

A few more Here's a video of a Carnival trailer an old timer built in his spare time http://i623.photobucket.com/albums/tt316/wallfish1/th_video.mp4

Spent the day out a small local show today.

Hi Gerry, You can swap that bolt/screw to whatever you want. Yes the head will unscrew and you can rotate the exhaust manifold and tighten back down. I don't know a torque setting but haven't had any trouble just getting them tight. Sometimes the gasket tears and will need to be replaced if it does. They make a gearing system for a bike application and it was called "Chicken Power". You can find some pictures if you scroll through the posts here. Friction drive on the tire but it sounds like this one is going to be a custom setup.

Your carb is probably from a Chicken Power bicycle engine. The primer wasn't needed because the fuel tank is mounted above the carb and the rubber stopper type carbs are the newest style. Hopefully the little rubber thingy isn't dried out and hard because we haven't found a way to replace just the little rubber, only change the whole arm if you can find one. Member Webhead may have some if you need one, he is also the same guy who sells the diaphragms on ebay. A good remote control fuel line check valve may substitute but I haven't had the need to try that yet. That's all that little ball or rubber does, check valve the fuel so it only flows in the direction of the carb. You can test that rubber valve by connecting a clean piece of fuel line and see if you can suck air past the valve. if you can, the arm will need to be replaced unless you can get it to seal properly. A new diaphragm will help pump enough fuel and usually needed to get these engines running.

THANKS again for the unit! I believe it will clean up nice and I'll post some pics whenever I can get around to working on it.

sent you an email

Thought about doing one for each year but I don't have that many parts or the steel to do it. BUT, I have a year to get it together! Quite a few people wanted to buy it and a few asked me to build them one but for the amount of time it takes, I'd have to quit my job and hit the lottery number to be able to pay for it and have enough time.

It made it to the show and met up with the original. The owner painted the first one but in my opinion, it looked better as a rat. The original was sold to the president of the WH collectors club 2 years ago and he ended up giving it to his neighbor because his kids had so much fun driving it around. I got the chance to meet the owner, his wife and his son. It was very satisfying to hear the stories of how much they enjoy it and to see the smile on that child's face as he climbed around on this new one. The new one was sold to the president again, same guy that bought the first one. I was very reluctant to sell it but I know it went to the right person. A grown man had that same smile as the child did!

IT"S ALIVE! I've been putting in plenty of time on this lately to get it done for the big Wheel Horse show which starts this Thu. Amazing how much time this stuff consumes! I usually just peck away builds in my spare time and work on things as the ideas come so I usually have no idea how much time goes into them. Set up for a test drive Almost there!

This video from 1929 concept was posted a few times on other forums. The thing I find most interesting, is how they used a steering wheel to control it vs. using levers. https://www.youtube.com/watch?v=zBjlSJf4274

Don't forget BIG. It's also got to be one of the largest O&R tools ever made too. Looking forward to seeing it all fixed up. What kind of tank do you think fits on there? 10 gallons maybe?

What a VERY unique and rare tool. Please keep the tool intact! Maybe one of the O&R guys over there will trade for a good engine and pump. If they don't, I would be willing to trade some O&R tools for it.

Nice Score!

NICE! Looks like you might need a water cooled engine for that one, not much air flow

Welcome to the forum! Engines should be fairly easy to find if you go with an air cooled engine. The water cooled engines are a bit tougher to find but they're out there too. Just do a search on ebay for Ohlsson Rice The Octura mount and out drive might be a bit tougher to find but also can be found with patience and persistence.

If you don't find one on your side of the pond, I have a K91 carb for you.
