That's great Rich, i could've kept my last echo going for a couple more years of i had the inclination, but 4 years out of a topper that gets used hard most weekdays is pretty good imo. Matty gets through one every 3 weeks and still wouldn't buy a 150.

 

Besides, 4 years with me as a 30- something year old climber is probably more akin to 12 years of your work in your 50s.

I do realise they are still lubricated by the oil in the fuel but...

But (my understanding is) that they actually run on a 4 stroke cycle and have sort of valves. Hence why they sound slower revving. If someone wiser can explain otherwise please do. This was explained to me by my local Stihl dealer.

They do and the fuel air mix also passes over the valve gear and into the crankcase, lubricating them so they still need a petroil mixture. Also I think that on the induction stroke some of this mixture is pumped into the cylinder.
