The obvious diagnosis is that you ran out of tallent:001_tt2:

 

Could be a number of things - a running engine needs spark, compression and fuel...it isn't quite as simple as that but it is a good basis to start from.

 

A few heat related issues: -

 

Fuel tank breather - try loosening the fuel cap and trying to start again

 

Coil - perhaps the coil is producing a weak spark when warm - check the flywheel to coil gap and the HT lead/plug etc

 

Compression may be low - do a comp check or at least check the exhaust side of the piston by removing the muffler - engines produce less compression when warm so maybe it is boarderline on starting and then not enough when warm.

 

It could be other things - did you over choke it and flood it when warm - pull the plug out next time and pull the saw over with the plug hole facing downwards and check for puddled fuel - it will run out if you give it 10 - 15 pulls on full choke!

 

Try these things and if they don't work I will give you £20 for it:thumbup:

 

One last thing - try starting it without using the decomp - the extra comp may help!

 

Oh - another - get someone to hold the throttle open when you pull it over - that usually works!
