Mity Vac didn't work on this one.

Needed the air compressor (at low pressure) to feed this hungry air leak 😄

Nice...bit of a rare one. I use a bicycle pump on my old gauge for big leaks as per you have found out, some leaks need a lot of air to diagnose where they are coming from.

Poor thing has been negleted and got hot - cylinder bolts were all but loose.

 

Then this happened while fitting piston circlip ....😨....💩

remember that type of thing happening on the old Stihl 010/011/012 models. Was a special tool to hold them in place.

Yup, had it on a 009....quite a shock and needed lots of grease and tweezers to rebuild it.

Exactly ! Surprise, shock, dispair....

Tiny click noise (rod becoming detatched I suspect) followed by several small things dropping on the floor, (saw was on its side while fiddling with piston circlip).Thought it was buggered at that point. But collected up all the rollers I could find, quick count up and a few sums later it worked out that side by side the rollers would wrap around the crankpin leaving 1mm gap. That'll do !

Cleaning followed by grease on rollers and crankpin.... 2 mins of sweaty palm stuff and the rod popped back into place. Found there was only one orientation of rod and crank where it would come apart so parked in safe position and retired for a break. 

Actually not too hard to put back together once all the bits were found but I did think it was game over for a bit.
