Good call there Converse a loose blade carrier is enough to dislocate you fingers
Cheers NormK, yes I only found this out as you know I want to take everything off the deck on my mower to give it a freshen up and put it back together again. I knew that is seemed to start fine before I removed the blade carrier, then after I removed it a few days later I just tried to turn the engine over with the starter and yes it pulled back hard and was locking up like there was no decompressor at all. I didn't force it more because it was that bad it felt like the string was going to snap or wreck the starter.
So the blade carrier weight must be there as extra weight and balance for the engine.
Cheers!
