It is indeed that one yes. I've stripped the head yesterday evening and that looks fine. The splines still look good and there are no loose or tight spots in the rotation. I guess that leaves adjustment of the carb (the throttle does not completely open) or checking the clutch.

Hi I have one of the above. not sure what they are called in English. Souped up strimmer with a blade? Anyway, I've just started using after the previous season and although the motor is starting and revving up ok it feels _slightly_ under powered and more to the point although the blade is...

Thanks @bertsmobile1 in fact what was happening was that the blade retention lugs had sheared and the blade was increasing the drag rather than adding to the rotational inertia and assisting the flywheel. Removing the blade allowed the motor to fire up perfectly. and replacing the blade support...

Thank you. I guess I will need a tachometer to gauge the engine speed after that. I am wondering whether the issue may also be due to the mower having had the blade stop a few times in long grass. I don't know whether this mower has blade keys or similar but the blade does seem to spin...

thanks @bertsmobile1 can you explain what a well adjusted governor should look like or perhaps how best to adjust it on this motor? I have the willingness and (possibly) intellect, but not the experience!

Thank you. I reset the throttle/choke cable and ensured that the butterfly valve was fully closed and retightened. Unfortunately that did not resolve the issue and the nozzle was clean when disassembled. closing the engine side butterfly valve does consistently start the motor however. The...

the choke seems to engage only the external baffle. but I might well have cocked up the linkages. here are photos if they help point out my errors! with the governor linkages remove the baffle on the engine side is pulled fully closed by the spring. I don't see the governor moving...

gaskets all check out fine. no tears, no obvious wear. i tried turning the engine over a couple of dozen times then checking the spark plug. Dry as a bone. So the fuel isn't getting in to the cylinder I guess. Either suction issue or a blockage in the fuel nozzle. If the gaskets are ok...

i see. the gaskets are all designed to be reusable and only one has actually been removed (which is between the carb and the air cleaner. It's a fairly simple design. but worth stripping them down and looking for anything wrong in those joints. thanks. will post back.

I changed the fuel pipe as the previous one seemed perished. it tore easily when removing from the fuel inlet. in replacing the fuel pipe I used one with a much greater thickness but the same inner diameter. The fuel still flows just fine and the tank empties quickly. The fuel bowl seems to...

Hi first post here - be gentle! I know precious little about motors, and particularly not the words used for various bits. I was asked to take a look at a neighbour's Stiga mower (combi 55 with a Honda engine) which was not starting. Engine had compression, spark was ok and air filter was...
