  1. Tecumsh MV100s as in Flymo

    Thanks for the suggestion but the MV100 is a different animal altogether. Two stroke not four.
  2. Tecumsh MV100s as in Flymo

    I'm looking for a standard size piston that's not been seized. Original part number 16095004
  3. Help with Ransomes parts

    Bartrams in Ipswich may be a good place to start. Long time Ransomes Dealer and just down the road from Ransomes themselves.
  4. Skilshop Chainsaw Clutch

    With most saws the eaiest way of locking the engine (bar having the correct dummy spark plug with a nylon buffer) is to remove the plug and poke two or the inches of heavy duty starter cord down into the cylinder and then rotate the engine in the appropriate direction to compress the cord and lock the crank. No danger of slipping and consequent damage, or have I missed something unique to this situation?
  5. Carb needed for Versatiller

    The Dellorto carb shouldn't be too much of an issue. The attached may help with linkages etc. https://www.dropbox.com/s/e0fwa1pd83mcn31/Aspera horizontal crank governors0001.pdf?dl=0
  6. Kohler Recoil help please

    That recoil is similar to the ones used on some iron block Tecumsehs and I believe was bought in from Fairbanks Morse. A few years ago I needed a recoil spring for a 10 hip Tecumseh and bought it from the States; only to find that it was off the shelf in the UK as a Kohler part.

    Toro now owns Hayter so are "rationalising" the parts bin.
  8. Bridges Mini-Mota 3 speed drill

    Interesting that you dealt with Rupert Ledger. They went into voluntary liquidation in 1976 . They were better known as manufacturers of ignition testing equipment and I have one of their portable test units. I also have a very useful gadget, the Dy-tone, that they made for ascertaining the condition and the opening / closing point of contact breaker points in flywheel magnetos without the need to dismantle - one wire to the HT lead and one to earth giving an audible signal that changes when the points open or close. A sharp change of note equals clean points and a slurred one, dirty points. Invaluable for setting the timing on early Villiers etc as being audible , hands and eyes are free to align timing marks etc. The company morphed into Ledger Selby and Co. Ltd and also traded as Uni-Pak Maintenance Systems. No mention of drills in any of the literature that I have.
  9. Avometer 8 Mark 5

    Nice bit of kit. I think that Avos were the gold standard of their day and there are still some applications where I prefer analogue to digital, but then I'm........... !

    The original coil armature on your engine would be a 298316 , to which you can fit a 394970 Magnetron module to eliminate the points and condenser but it may be less hassle to find a newer 397358 coil, that already incorporates a Magnetron trigger module, from a scrap engine. When shopping for a new / used coil take yours and make sure that the spacing of the fixing holes exactly matches as there are some minor but important differences in the spacing on otherwise similar-looking coils. Any coil from a 13 series engine should fit.
  11. Nice little Drill Project

    Forgive me for gatecrashing this thread but here are a couple of images of the bench drill that my father bought for me in the early 1950s. It has MRL and the numeral 5 cast into the flywheel and MRL into the underside of the base but I can find no information about the manufacturer.
  12. The Beast is alive and well

    Taking the trenching suggestion a step further , could it have been for tree planting on rough hilly terrain ? The Forestry Commision used much larger versions when establishing acres of coniferous woodland.
  13. Westwood Gemini rotavator

    All looking good. What’s the secret of achieving that standard of finish during the winter weather?
  14. Hayter Harrier 2 drive problem

    From what you are now saying it sounds as though you are looking at the plastic casing around the original external dog clutch assembly and if the “ no drive “ was sudden it is likely that the failure is either of the roll pin holding the drive half of the dog clutch to the APTO shaft , or the roll pin locking the bronze gear within the sump to the Auxilliary PTO shaft has sheared. A quick test is to remove any covers so that you can observe the shaft where it exits the engine, engage the dog clutc and try to push the mower forward . If the internal pin has failed the pto shaft will rotate freely allowing the machine to move. If not it will lock. Replacing the internal pin may be done through the small removable plate in the engine sump but only if you can account for all the broken bits of pin, otherwise it’s a sump off job. As an aside to your issue , neither of the halves of the dog clutch are still available unless you can locate any New Old Stock. I’ve seen various attempts to “ dress” rounded off dogs to achieve more positive engagement - not many successful, so it’s important to preserve what you have by correct adjustment. A factor that defeats this is wear within the sump allowing excessive APTO shaft end float making correct adjustment impossible. Briggs answer to this was a new sump and bronze gear but we developed a solution using a 50p thrust washer from the Qualcast parts bin. A proper investigation and , perhaps, an image or two will save a lot of guess work.
  15. How rare are sears tractors in uk

    Their rarity depended upon how close to a USAF base you were! We came across a few that had migrated from East Anglia having been originally sold through their PX stores on the larger bases. Plus one private import by a Virgin Atlantic 747 captain!
