Chainsaw wont start

Oh dear!

Mmmm:001_rolleyes:

 

An engine should have spark, fuel and compression. If the plug is dry, you have no fuel, if it is wet, the carb is throwing out fuel. It obviously isn't this simple but these are the basics when analysing engine faults.

 

I guess this one may run and run......and run or not as the case may be:lol:

I just tested, there is a spark and there is compression.

 

I adjusted the H screw like you said but when i went to adjust the L screw i couldn't find it so i took the carb off to adjust it, then when i pulled the carb off the L screw just fell onto the floor, so i put it back in and twisted it one turn.

 

So i have two questions, is the L screw meant to fall out?

And is there any other problems that could stop the saw from starting?

 

Thanks very much

If I were you Harry I would find someone else with a running Stihl MS230 and swap it while they are not looking Is the carb Walbro or Zama ? You can get one on ebay for under £20. The screw shouldn't fall out and there are lots of possible reasons why it won't start.

Haha wish i could do that peat,

The carb says Stihl and Zama on it

Only if the thread is stripped. Maybe you just wound it out too far.

Check the screw still has the tensioner spring on it, screw it back in gently till it seats then back it out one full turn and try starting your saw as normal. It will take a few extra pulls to get fuel through as you have had the carb off but as soon as it coughs drop the choke lever to fast idle and pull again.

I couldn't see a spring on it, but it still screwed in, is that ok?
