Hello! Can anyone help please? The last few days I've had a mysterious smell of burning rubber in my cab, starting about a minute or so after the engine is started & easing off as the journey progresses. Opening the bonnet didn't seem to reveal anywhere in particular the smell was coming from, though in the cab has bin getting a bit worse, so I tried not to use it. Today I removed the casing below the engine to look &change the oil & discovered the cause- sort of! Can anyone possibly identify what these vague bits can be please, something's melted & the following had fallen off into the casing!! Much obliged thank you!

ahh, no photo facility! I have some but don't know how to post here, so here goes : several melted plastic rings so presumably was one! 7cm diameter, one plastic cap, raised a bit in the middle 5cm diameter, with 8 small slits in the vertical sides if you lay it flat. metal circular ring 4cm diameter, 1 1/2 high with looks like bearing-racer track inside & 6 bearings about 1/2cm across !!

The engine still starts &runs (though I'm not using it) strangely! What can they be? Very vague shot in the dark I know! Thank you
