    Thanks, Bertie! I need to research that MAR business, I hope it is one, but I recall they were called Plonkers back in the day.
    I just completed some work on it which I plan to post up in the trials thread later. Hope you and Crusty are well, Gerry

    Awsome! I think you will be impressed by the build quality, a bit like BMW's. They all got parked back due to lack of spare parts and service back in those days. I look forward to seeing some pics of what you get!

    Having put about 3-400 miles on the motor, I decided to pull it down to make sure the pistons and cylinders were living a happy life and to see if it needed to be decarbonized. Pistons looked great, I'm glad I gave them an extra thou running clearance. Exhaust was heavily carboned. Pieces resemble a prehistoric fish skeleton! I'm using cheapo oven cleaner on the parts. Will replace the "steel wool" stuff. Snap-on lift goes to 4 feet high. Ideal for seeing the bottom of the motor :) Engine has to tip forward in it's mounts to get the cylinder off. Also giving it a general tune up and a few little fixes. I wound the kickstart spring a little tighter and also increased the tension on the clutch springs. DSCN6007.JPG DSCN6009.JPG DSCN6011.JPG

    Binding twine is an element of sealing the internal components of the baffle assembly. Note the new "steel wool" pan scrubber inside the baffle :) DSCN6028.JPG DSCN6029.JPG

    Not to mention, I cleaned the parts with Dollar store oven cleaner!

    My baby Sears left me stranded, on and off electrically dead. The problem turned out to be a fairly new battery that was intermittently defective. In my 40 plus years of troubleshooting I have never seen anything quite like it. It took a number of days in the workshop to pin down the problem. If I had known this was the problem, I could have gotten home on a 6 volt lantern battery! I'll carry one as a spare from now on. I was thinking of wiring one in series with the existing 6 volt system to power a 12 volt Garmin and my cell phone charger anyway. Here is a pic of the lengthy troubleshooting process and the nature of my temporary repair. The defective battery is visible near the front wheel in the first picture.

    Thanks for the great info here everyone!
    I just picked up a 250 (motor only) that is going in a custom built chassis.
    Very excited to hear her run!

    I've had Sears/Puch 250s for over 40 years, probobly the most under rated and under apriciated antique bike ever. IMHO.

    I just noticed my old PUCH mouse pad is being used to pad the battery in the last photo!

    I have enjoyed this thread and found it to be a source of knowledge and inspiration . So after reading the section on stripping , cleaning and rebuilding the exhaust I decided to copy and do the same on my own bike . The use of pan scrubbers in the exhaust baffles is a stroke of genius and news to me but I like your way of thinking . I have a lot more work to do since I bought the bike in May 19 as a non runner with no papers . I have particularly enjoyed meeting people in different parts of the world while gathering parts and knowledge . My latest purchase is the front fender which came from Das in the Netherlands and before that the exhaust header pipes were kindly provided by Troy from Los Angeles . I am currently seeking an intake silencer for the carburettor , it intrigues me who I will meet from what part of the world in sourcing that particular part . Below are pics of as bought and how it currently looks . puch 110519.JPG puch 120720.jpg
