hello,
I'd like to use my stihl 070 AV for milling.

It looks good but there are some things wrong with it.
I has a low compression. I don't know why. i pulled the muffler and the cylinder and checked for scratches on the piston. but it's clean. i checked for broken rings but there still intact. i checked the carb but its still super clean, decompression button works good as well. i don't have a compression guage but it's just so easy to start for a 100 cc saw..

starting this old stihl contra takes a lot more effort than starting the 070. but they have the same cc's. the 070 also dies when you actually put it in wood.
can a re-ring job fix this? or do i have to buy a new cylinder and piston (which is no problem at all, i can always buy a aftermarket stihl 090 cylinder and piston)
maybe it's a gasket issue? any thoughts appricated!
problem is i don't know the history of the saw, but i got it from a collector in belgium who got it from a stihl dealer, but he sayd it belongs to some dude who was in the timbersports.. but he didn't race with this saw or something, just owned it for fun i guess
but this metal plate between the carb and the cylinder does not looks stock to me...
can it be benefical?
