    Dolmar/Makita had a habit of changing fw/coil combinations mid run without changing how they fit.

    If you have a timing light with timing advance ability, you can mark top dead center on the fly wheel and the corresponding spot on the cylinder and use the advance feature to find out when it’s firing using a drill motor to spin the crank. If it’s somewhere between 24 and 30° BTDC, I’d say you have the right combo. It would eliminate that part of the problem

    I'm going to see if I can get a timing light with advance adjustment and give that a try. Thanks

    LMAO! Im doing good Cuz! Been back at it full tilt for about a month. Still got some nerve pain in the legs and feet at times but im like a dog out of its cage trying to make up 8 months of life. Feels good! IIRC correctly Corey told me u wound up with the 510 and got it running with a different coil than the one i had got
    for it. :nusenuse:
    That saw i had was mint! So frustrating......only saw that ever stumped me and i kinda gave up being my only Dolly at the time. Thought it wasnt meant to be:risas3:
    I think Kevin has the OP on the right track. :headbang:Seem all ive read on them 510’s its all with the damn FW/coil. Its like ya have a good one or ya don't.

    I would also go down this road dolmar did some stuff like this on 9000/9010 too flywheel position was about 90 degrees different on some. So if you knew the timing you may just be able to clock the flywheel different and get it running.

    This is only the third Dolmar I've ever worked on. The other two were 7900's. Normally I play with Husqvarnas and Stihls, plus the occasional McCulloch restoration. This thing has me pulling my hair out!!

    Wow, Small world for sure. I'm right across the border close to New Bedford. Sure you know where that is. If you want to borrow the timing light let me know. I'm doing 6 days a week with long hours but could make something work on Sunday if needed. Let me know. Thx. TG

    I located a friend with the timing light I need. I have a couple saws that came in for a local tree service. So once I get them finished I'll play with it again. I'll update the post once I have more info. Thanks for all the suggestions

    Been a while since I was able to get back to this saw. I did get the timing light on it and I couldn't get my marks to line up at TDC no matter where I turned the dial from 0-50°.

    You could grind off the keyway and do trial and error until you got it at 30° btdc. That’s how I did my first 7900 with a 272 coil swap

    Or get the correct coil/crank/flywheel combo for it
