Husqvarna 540 mark 3

[andym31]

Has anyone had any issues with the mark 3? 

 

Mine sh!t it self last week blowing the plug out its housing stripping the threads

Its either not been tightened fully or had dirt in the thread - making it feel tight but still being loose. I had the same on my CBR600 motorbike.

 

Should be quite easy to helicoil. Best to pull the cylinder off first so it can be reassembled clean, but on the CBR6 I helicoiled all four in situ as getting a 4T bike engine apart and back together is a fairly huge job.

 

If you do it with the saw assembled, set the engine with exhaust port open, use plenty of grease on the tap to catch any swarf then flush it out with 2t mix fuel.
