Husky 235 won't start

[djbobbins]

I mainly use a saw for domestic logging so have got a Husky 235 for this purpose.  It is about 6 years old but hasn't done a huge amount of work.  

 

Most recently, it has been stored - empty of fuel - for about the last nine months in my garage.  Earlier this week, I bought some fresh petrol, mixed up 50:1 with Stihl 2-stroke oil, fuelled the saw, primed the carb and it fired on the second pull of the cord.  It bogged down a bit during cuts and on a couple of occasions died after the end of a cut, but always restarted straight away.  I was therefore thinking it needed tuning.  

 

Anyway, the next evening I got the saw out to do a bit more logging, tried to start it but it was having none of it.  There is fuel getting to the cylinder, but when I took the plug out, earthed it on the cooling fins on the engine and pulled the cord, I couldn't see any spark - even in near darkness.  I'm guessing that's the problem but wondered if anyone had any bright ideas?

Disconnect the wire from the coil to the cut out and see if you get a spark. Put a teaspoonful of fuel straight in the plug hole and warm the plug then put it back in and pull it with no choke.

Try another plug and do the test in subdued light. It is easy to miss a spark on some saws! 

The carb most likely needs an overhaul and tune.

The coils are poor on these saws even more so on recent 236 models and often give carb symptoms but it's the coil that's breaking down

Took it into DC Burgoynes and they had it sorted in a few hours - cleaned the carb and fitted a new plug.  

 

Out of curiosity / for future reference, has anyone any experience of using carb cleaner on 2 stroke engines?

I always use carb cleaner to clean carbs when I strip them, fire it through all the channels and fit new diaphragm etc. Do you mean easy start?
