hi. I have done a search but have not found anyone with a similar problem. I have a stihl 010 with poor compression, reads about 50psi, crazy thing is it will start and run but flood at idle. I swapped out a the pistion and cylinder with one off an 009 that had just pumped 140psi. again it only pumped 50psi on the 010. am I missing something else, I am going to put the 010 p&c on the 009 and test it tomorrow just to see what the tester shows.
Regards Callum
