Stihl 026 query - purchased 2nd hand

I’ll run it at the weekend and see how it cuts.
I don’t have a pressure/vac tester but might try the starter fluid behind FW & clutch to see if there’s a vacuum issue.
Either way I’ll pull the cylinder to get a better look at the piston/cylinder/rings to assess them.

Decided not to run it yet until checked a few things

Got myself a vac/pressure tester

Holds good Vacuum at -10psi for over 5mins
Pressure 10psi dropping to 8psi after 5mins
I think that’s a decent result
I plan to run it briefly just to get a feel for it and look at then pulling the cylinder and see what I’ve got. Best case I guess would be a cylinder cleanup and likely new piston.
