Dennis Message Board Back to Home Page Members can Submit Messages - Please Log-in Dennis Society - 20th August 2025 Help and Advice Wanted - Dennis O6 Engine When the engine is cold it behaves perfectly - ie starts, runs, slows down and stops normally. After about 15 to 20 minutes, ie when warmed up, it still starts and runs, but does not slow down when the throttle is returned to idle position. It keeps running at its last speed - only slowing very slowly (like several minutes to slow down), making it completely undriveable. Also, when warm, it does not stop when the throttle is pulled up to the "stop" position - it just slows down, but keeps running very slowly. Oil in the governor weight compartment has been checked, by removing the screw plug on the side which gives access to the governor weights (Item 31 in Fig D7 of the Instruction Book - not to be connfused with the oil in the injection part which has its own dip stick. The oil in the governor weight housing is not visible with the plug removed, but when running the oil sloshes all round, showing it has plenty of oil in there. There is no dip stick for the oil level for the governor weights, and the instruction book gives no indication what level the oil should be. Should the oil level be up to the bottom of the threaded hole for the screw plug? The instruction book just says SAE 30 oil should be added through the "lubricator" - item no 5 in the same diagram, Fig D7, but gives no advice on how much oil to put in. Any help and advice would be most welcome Contact the Secretary secretary@dennissociety.org.uk Dennis Society - 16th July 2025 FOR SALE Dennis Pax NFM16 The owner has been working on the vehicle for quite some time but other matters have now interveened and he wishes to pass on the project.

The main challenge is that following Malcolm's death last year the solicitors handling his estate, having previously restricted access, have now decided that they will begin to clear the site very soon. This means that the mowers will be sent for scrap unless new owners can be found for them in the next few weeks. There are over 40 Dennis mowers dating from the 1920s/30s through to the 1960s/70s in various states of repair. These are generally "non-runners" and several are incomplete but there are plenty of spares so it may be possible to find "missing" parts to make up a complete machine. In addition, there are approximately 15 machines from other manufacturers. We have been liaising with the solicitors and has visited the location of the collection in Dorset with other club members to assess what is there. The photos below give an idea of what is available. Access to the site is restricted but it is possible to visit by prior arrangement. Seb has offered to co-ordinate with the solicitors if anyone is interested and would like to view the mowers.
