Sachs Dolmar chainsaw won't start

SD114 chainsaw won't start. There's a healthy spark at the plug, fuel lines checked and in-tank filter cleaned and blown through with compressed air and fresh fuel mixed and put in the tank.
I think that the problem is with the setting up of the three jets on the carb.
The saw was a non-runner when I bought it and I've tried adjusting the settings without success.
I feel that I need to start from scratch with the adjustment screws. How far should I back off the H & L mixture screws and the main speed adjustment screw initially to at least get it to fire up?
Anyone know the initial settings?
Thanks,
zeb

You say it was a ""Non-Runner"" when you bought it??? Is it an (~5years) older saw??? If so,, Just go ahead & replace the carb kit (don't just "Clean" it ) & the fuel & lines & filter... If you have good spark & the piston is O.K. the next thing I can think of on an older non runing unit is to overhaul the fuel system Start with the screws 1 1/2 turns out from LIGHTLY seated & tune from there...

Thanks Roger,

I came across the saw at the local recycling centre and the operator only wanted 5 for it as it was a non starter, so I couldn't leave it there could I?

Don't know whether I can get a carb kit for it on this side of the pond but I'll try tomorrow when we do the weekly shop.

Piston and bore look ok and there's good compression, so I'll have a go at starting it in the meantime, using the settings that you suggest.

Thanks again,

zeb
