BVS 143. This part which I suspect is intended to be a debris shroud and possibly a cooling aid sits below the recoil housing and span with the flywheel. Lately the engine started making metallic banging sounds which I now know were this piece knocking against the flywheel. In the first video...

Thank you - at least that's eliminated. Understood and well aware that's what's in the manual. It's maybe a couple of cms below to be clear, still well up in the dipstick thread. Unfortunately - and while this is no excuse - the engine hasn't really been best looked up after but. To the best...

This is a continuation of sorts of my last thread from over a year ago. My dad has a Tecumseh BVS 143 on a Mountfield Empress 16, we believe bought in the mid-80s. It gave very good service for about 30 years but missed several seasons over the past few years, predominantly because for a long...

Got there via help on another forum - the basic owner's maintenance guide I had been reading said to turn the idle screw in and then back out by one turn when resetting the carb screws. Turns out that should be more like 4+ turns out... Although I'd been adjusting it either way (with no real...

Here are some photos with the throttle lever in idle position - as previously stated, revs remain constantly high irrespective of throttle position: In the final image I have highlighted some areas of interest (to me): - The red boxes, I'm not sure what they are, they rotate when pressed and...

I'm not too sure what to look at next. Starting enthusiastically every time but I can't get the revs down. Carb mixture and idle screws don't seem to have an effect. Throttle lever looks like the linkages are moving OK but revs remain constant all the way to stall.

Some photos prior to the starts this morning - the spark plug is oily as removed this morning. One thing I forgot to mention - the owner's manual/maintenance guide I linked above shows a round gasket inside the air intake in the air filter cover; it's missing. Not sure if it's an issue or not...

Hello, thank you for the welcome and useful information! A quick update of the morning's work. Got the mower out the shed this morning. First got the air filter cover off again and checked the air filter to see if it was oversaturated. Didn't seem to be. Took the pull cord assembly off the...

Hi all, new here, We've got a mid-80s Mountfield Empress 16 with a Tecumseh BVS 143 engine. Solid machine which ran flawlessly until a few years ago when it got progressively more tricky to start and ended up being retired due to inheritance of another machine. Cut a long story short, I want...
