    Upon opening the engine I saw this. A strange valve setup so I stared at it a bit confused as I can't recall ever seeing this before and was also questioning my memory.

     

    Well, as it turns out it's one of those rare and coveted Octura made valves.

    Strange that it would be on a TT 400 but maybe they ordered them for manufacturing these???? Maybe David @factory might have some insight on this. Unfortunately there's no model number stamped into it and the air baffle is a clean one so obviously changed.

     

    That looks to be a replacement engine, the TT400 here has a Type 112, the wear & corrosion on this engine match the rest of it, the original list would confirm it. These earlier engines are the ones with the nylon bearings, it's possible the original engine self destructed in some way, or was too challenging for the last person to fix.

     

    Nice to finally see what the Octura rotary valve looks like.

  2. The non-serviceable bit relates to a seal, the later type of seal that is bonded to metal ring, which can't be removed without destroying the feather valve assembly, due to the bearing being pressed in, blocking access. The service bulletin is S-E 093, which was added to this thread;

    They eventually made the same change to the induction housing too, must have increased profits on service parts, why change two cheap seals, when they could sell a complete new feather valve & induction housing.

    This is just a guess as to how the engine mounts and allows for reverse.

    It's also possible to slide the engine instead of tilting it

    The auction link in post #1 has a description of the reversing lever, I was thinking the same idea, the belt is loosen to slip and the flat part of the pulley is pushed towards the rubber tire on that large internal drive pulley.

     

    Quote

    It was powered by a two -stroke engine with an integrated fuel tank and a centrifugal clutch and had a reverse using a reversing lever located in the cockpit, while the start was by using a pull cord launcher. Powered by an American brand called Ohlsson & Rice, whose primary use were for chainsaws and other similar equipment, the engine had a displacement of 20cc, a cooling fan and a hair-raising max power of 0.86bhp, which allowed aspiring racers to get to between 15 and 20 km/h.

     

    So we have several pictures showing the larger size double reduction gearbox, this narrows it down to Models F & J at 900 RPM or Models U & V at 1750 RPM, the model or type is on the opposite side to the serial number, exactly where no one would photo it. Models J & V have a clutch fitted.

  4. No spare gearboxes here, they are quite hard to find, most engines (that aren't part of a tool) seem to have them removed over here, to use in RC applications.

     

    Also I don't actually know the correct engine model/type with gearbox that was fitted to this car, it's not listed in the O&R model index, ideally we would need several identifications to confirm the correct type, I'm not convinced the one I saved pictures of has it's original engine, it's too clean compared with the rest of the car.

    The last guy I helped with parts never replied, when I asked about the type/model. :banghead:

     

    Another question I haven't got an answer for, what is hidden on the inside of that pulley? There has to be a reason why it's extended.

  5. After comparing a lot of different part numbers, I've finally figured out the correct engine type, which is Type 13B340.

    The induction housing assembly was the part that changed, 13B340 used the older type A-13-18 that was used in most engines from the approx 1965 onwards.

    And 13B406 uses the newer type 400563 which has two extra screw holes, to directly fix the feather valve assembly to it.

    Take note of the different spacer used under the cylinder too, these are original.

     

    Scan of parts list/diagram to follow...

  6. Thanks for that picture, the O&R branding should date the engine to Nov/Dec 1974 or earlier.

     

    There are two possibilities for the Chicken Power engine, with the threaded exhaust manifold, remote mounted fuel/gas tank and a silver painted /starter blower housing with toggle switch (the numbers in brackets are the release date from the O&R list);

     

    Type 13B-340 (7-1-74), this had a flexible exhaust pipe.

    Type 13B-406, this has a tube exhaust pipe.

     

    I'll have a closer look at the part number differences another day (the carb parts differ between the above two engine types).

     

    Other engines that it can't be are;

     

    Type 13A-181, older style engine with round starter mech.

    Type 13B-328 (8-29-73), has five cup exhaust muffler.

    Type 13B-341 (1-21-74), has five cup exhaust muffler, but could also be supplied with threaded adaptor.

    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.

    Can you confirm if it has AEP or O&R on the decal at the top of the blower starter housing? I'll see what info I have on this one.

    I am putting a new rope on a chicken power recoil 13 b engine and I put the knot on the spool comming out the flywheel side and it rubbs when I tighten the recoil. If I put it on the spring side it interferes with the spring.

    Maybe post #9 here will help, I added a short guide to reassemble the 13B starter (note 20A engines are different, as they were made in both rotations).

  9. The type 133 is actually the engine for the military version of the Kenco pump, as seen here;

    I suspect the original engine was red, as the rest of the pump is. Also the standard muffler was not supplied with a type 133, due to the military using a different type (also shown in the above thread).

     

    Need to check the information for the other engine types used on these later Kenco pumps, earlier ones didn't have the engine directly bolted to the pump housing.

  10. Will PM you tonight, only have the diaphragm, cover gasket & plastic check valve (not usually required for later engines).

    No one seems to make the crank seals in the sizes O&R used (expect the front crank seal, which someone on here found a modern replacement for), we have to use O rings to replace them, no idea how long they would last, mine only get run for demonstration purposes, note they are very loud.

    i WAS WONDERING HOW WERE THE OHLSSON CRENE GENERATORS. i READ WHERE THEY USE BATTERIES TO START THEM?

     

    If you meant the Creme Lure generator, the batteries will not start the engine, they were used to boost the ignition circuit only, probably not a good idea to add extra voltage to boost 50+ year old coils.

    As with anything using batteries you may find some old ones fitted, I did in mine, of course they had leaked & made a right mess of the battery terminals. :banghead:

    Lastly the plastics used for the tank & frame do not age well.

  12. As it's the Perry branded version I guess you are in the UK, I still have a few reproduction carb diaphragms for these older type 13A engines.

    The owners manual can be found as a pdf, in section 4 of the manuals thread here;

     

     

    Note these engines aren't the most reliable things, even with a carb rebuild and avoid modern ethanol tainted fuel, as it does no good to vintage engines and the seals & fuel lines, etc..
