Hello all I just put my first saw together after a complete tear down. It's only a strato poulan 4218 but I would like to pressure and vac test it. But im not sure how. I have a mighty vac but not sure what to do. Thank you

I use a bicycle inner tube to plug off exhaust using oem muffler, install it like a gasket behind the muffler. Install spark plug. Plug male end of your mityvac into the impulse line and bam, your in business. I usually do a pressure and vacuum test before and after I rebuild. No more than 7psi both ways as you might damage the seals. Also some chainsaws impulse line is built into the handle assembly and can be trickier to deal with. Anyways good luck! The two videos above are pretty good explanation.
