Thanks again mate, great advice. I know the carb is super clean I had it totally apart and cleaned out, but I'll take your advice on the intake rubbers and pin rubber.
I'm pretty sure I seized it as it was running well then just stopped pretty quick, no momentum run down at all. I couldn't move the starter rope at all, abut once it had colled down it would turn over again.
I'm not inclined to start it up again until I pull the motor apart and have a looc at the piston and bores.
I was thinking that I'd need to buy another mower, but the price of engine parts seems reasonable enough to make an engine rebuild pretty economic, depending on the cost of any special tools required.
