Pioneer 610 update:
Somewhat determined to hear this beasty lite off, I pulled the plug to check for spark. Beautiful bright blue So off comes the new filter and I poured a little mix down her throat. Pulled and whattya know, I get 2 pops, and another 2... Took it outside an hollered @ my son so he could be there cause I think it's going to run. Only get pops, again. I get him to give it a little throttle while I pull and BAM! We have us a runner!!!!!
First time running/cutting in around 50 some years. made in 1959 and 103cc's.
The cover doesn't tighten down so I need to cure that and get a decent chain...
Kris, it's a .404 .050 with 62dl.
Your saw is missing its air shield and cover bumpers. This is a critical piece on the 600 series Pioneers, you will overheat the cylinder and score the piston running one without the airshield to capture and redirect the airflow from the flywheel. Your cover will not tighten down without the airshield and the two rubber bumpers that mount in the holes top side.
