My old yanmar
ysm8 overheated ( no alarm
It had been hard to start when cold so while replacing the impeller (root cause ) and muffler
which melted, I decided to pull the head
off and check the valves.
They were a bit rough so I lapped them hoping it would improve cold starting.
Late Sunday everything back together and engine
starts easily (yay ) ran for a few minutes then shut down.
I didn't get back out due to violent storms for another two weeks ang now she won't start.
I have bled the fuel
again and am getting fuel
to the injector.
When I had the injector out to clean it was very hard to get the needle out, had to use a little heat !
Even after cleaning
it would not slide easily, I have removed it again while I can get it out it's not easy.
I'm planning on taking to an injector specialist (any recommendations Sydney
So my long winded question is:
Could the sticky needle be the cause of no starting ?
