Ok everyone first time posting here. I have an issue....so I decided it would be a good idea to buy a stihl ms170. 40 bucks I said what the hell...yes it had a busted piston no idea why. So I replaced the piston I get it together and it won't start...at all. Pull the carb back off and look into the cylinder I see the dam piston doesn't come past the intake port....so it doesn't let in any fuel or air. Saw spins over fine but the piston doesn't extend past the intake port...am I missing something here or am I just stupid. Leaning towards the latter but what the hell. Both pistons old and new were the same height..pin height and skirt height...it was an identical piston from stihl. Someone have any input trust me it would be very appreciated.
