Ohlsson and Rice mini 2 stroke engine

Recommended Posts

I thought I would put an update on this little engines progress.......

Once stripped down it became apparent that the piston and barrel would be one forever more, despite my best efforts to separate them! A little too much force and the piston was holed..... Here is the broken barrel and conrod.

The carb was stripped for an inspection and overhaul. I discovered the fuel shut off valve(ball bearing) is missing, along with the choke lever and the air cleaner. I have replacements coming in from the US of A...... I have already had some bits come over, a replacement barrel and piston. New set of seals and gaskets, a new spark plug and a carb overhaul kit.

Managed to get it all back together, but without a spark...... A quick chat with Wallfish and an exchange of photo's showed me that a wire was in the wrong place. Once rectified, a healthy spark was produced. I was so tempted to try the engine, despite not having a working carb. So I squirted some fuel in and gave it a pull! The 2nd pull and away it went....... not for long, but enough to be happy with the progress.

Next was to attend to the paint work. The fuel tank had a couple of small pin holes. Once stripped of old paint I was able to solder repair the pin holes, then apply some filler to smooth the dents. Next came a coat or 2 of etch primer and finally a couple coats of top coat.

Gave the starter housing the same treatment........ New decals are on the way too!

Cheers Paul, just need to find an application for it now? Not sure what though as the reduction gearbox does slow down the output speed considerably! Any ideas guys???

Mini bike is a good application. That shaft setup is easy to put a pulley or chain gear on so anything you can drive with a belt or chain will work.

water pump

small air compressor

scooter

They also look good just as an engine display too. Make a nice mount for it.
