I do lots of Honda services and whilst I hear of cam belt troubles, I have never had them. I guess my luck will change now since posting this though!

 

Keep us posted on this problem and how you cure it, I guess they need new belts.

This is why we are puzzled,weve serviced hundreds of them over years,Its got us scratchin our heads,i will admit,Same oil weve always used,same mechanics ,Were evan wondering if they just dont like the cold!!

You may be on to something there, you would not usually be starting mowers in sub zero temperatures. The belt will be stiff and the oil will be very thick. Its probably not as cold down here.

 

You may find it is just a very strange coincidence. A few years ago I had 3 governors fail on GCV engines in a few weeks. I started to believe there was a weakness, but never had one since.

 

And like Stihl FS55 etc coils, OK, we know they are weak, but I had 6 fail in one week recently, and that was one after the other, after the other. Have not had one since.

Thanks for your reply,The only common factor we can think of is the cold,as you rightly say oil was very thick,and belt had become very stiff ,better turn heating up in workshop ! was minus 6 at lunch time today,I know what you mean about fs 55 coils,i had a right run on the my self not long ago,thanks again.
