    Ok folks, what y’all think of this saw. I’d like to hear it, good bad and ugly.
    Just bought one. Used. Less than a gallon of gas burned in it so it’s probably just broke in.
    Young guy bought it to clear some scrubby brush in his little backyard. Not a saw guy. Cut a branch under pressure and got whacked in the nose. The end of his sawing career. He bought a big screen tv instead :)

    Seems they have respectable power and speed. Heavy in comparison to my 550xp. It’s German made I guess so that’s something.
    Let me have it.

    Made me chuckle at getting whacked in the nose... I've read good about the saw but no experience first hand. Hope it treats you right.

    I have a 5105 and love it. I believe the 510 is an aluminum case chassis and the 5105 is magnesium. Definitely one of the smoothest saws I have used and has good torque for a 50cc.

    Yep, yours is lighter. I think the first model in the pro series. This is like a semi pro I guess.
    Do you have this easy start feature? I’m not entirely sure what that means, about to google it.

    Then you may like this. This was a quick purchase. When I first looked at it I noticed the teeth on the chain are covered with burnt wood residue. Just like running a dull chain but the entire tooth was covered. Figured the chain was boogered up bad. Teeth seemed sharp. Let it slide. Chains can be replaced.
    When I got home I looked a little closer. Back of the teeth are chipped up. I wonder how long he was running that chain backwards? LOL

    Yes mine is the easy start and it works ok, although, I don't see the need of a starting aid on a 50cc saw. It adds width to the saw and I would prefer to have a regular start. It basically works by pulling slowly on the rope and the easy start spins the engine over with very little effort.

    When I bought my 5105 there was a 510 on the shelf beside it. The weight difference is there, but I don't think it would slow you down much if any. I don't have a problem with the width of the Easy Start, even with thick winter gloves on.

    I don't have any problems with the width other than adding unnecessary bulk/size.

    I have one I bought from a buddy last year, he bought it new used it once and then it sat for a year and he couldn’t get it to start back up. So I took it off his hands and I’ve still never got it running, tried cleaning carb and rebuilt the carb, new spark plug and still nothing, I got fed up with it and it’s been sitting on the shelf for about a year basically new. I would love to sell it, if anyone be interested let me know. So I can’t give you any experience as far as running goes. Seem like well built saws though

    This one hadn’t been run in quite sometime too. I’ve seen in the reviews it can be a problem.
    Kid told me how fussy it was to start. Gotta follow the directions exactly. He was reading and I was doing what he said.
    Didn’t make sense but he was telling me one pull on choke then switch it to run. He was wrong.

    Anyhow he threw in one of those decent gas cans with the push button but told me the gas was probably no good.
    Emptied the saw this morning and sure enough. It was brown and smelled funny.
    Pulled plug and pulled it over for awhile. Turned saw upside down and pulled some more. Lots of fuel came out the plug hole presumably from the crankcase.
    Plug back in and pulled for awhile. Nothing. Pulled that little cover off the top of carb and saw a Swiss watch :)
    Nothing for me to tinker with at the moment. Back together, pulled a few times and it coughed. Wasn’t happy coming back to life but eventually it ran. Seemed quite underpowered and boggy.
    Bucked up a log and it began to run better, crisper but was missing on occasion. Chain needs a sharpening.

    So in my infinite wisdom I begin racing the crap out of it hoping to clean the snot out of it. It’s skippimg a bit from time to time and cleaning up when running good.
    Then suddenly it just stopped,,,,,dead,,,,,fast. Figured I seized it. Took the plug out and yes it’s running pretty hot. Melted the bed liner on the truck. Not sure I’d ever seen that happen before.
    Pulls over goo though. Doesn’t appear to be seized. It is running lean though. Can’t see any spark from the plug. Gotta try a new one

    Does anyone know the adjustments on the carb? I doubt the kid messed with them but maybe one of his expert buddies was playing with it. I’ve also seen users say fresh from the factory these things are dialed in dangerously lean. Only had it running maybe ten minutes but that plug is cleaned up and a very light shade of grey I’ve never seen before.
    PS I use VP 50/1 mix in the bucket. I did add a little extra oil to the tank just now when I filled it up. When I was running it I was running the straight VP 50/1
    Gotta see if I can find a plug for it today.

    Put in a new plug. It’s getting fuel and has what I would classify as weak spark. Subjective thing I’m sure.
    Won’t start though.
    I did buy this saw to tinker with but running first would be nice :)

    What do you mean "racing the crap out of it"? If you are wide open throttle be sure it's buried in some wood otherwise you are a lean size waiting to happen.

    No doubt your right. My indoctrination to 2 strokes is motocrossers from the 70’s. If they weren’t running right it’s because your not beating on them enough. Wide open is the only way to run em. If that don’t work shift into neutral and wide open for awhile to clean em up. That attitude still carry’s over to today. Most likely we were just not adept at tuning and the plugs of the day just weren’t capable of what those engines were asking.

    New plug and it still didn’t start. Did a lot of reading last night and seems it’s partially my fault. A lot of folks say it’s very difficult to hear the audible pop on choke. Others say 1 or 2 pulls on choke and switch it off wether it pops or not. Seems these saws are very easy to flood. My hearing is shot so I’m probably not hearing a very muffled pop from this thing. No problem with my other saws but,,,,,,,
    Pulled the plug this morn and pulled it over upside down. Gas came out. I’ve never done this with any motor before but it worked the first time. Worked this time too. Plug back in. Started and ran on first pull with the choke on. Never had a saw actually start and run on choke. This things just a different beast. Ok not really a beast. A dog compared to my 550 but I’m gonna go buy a good chain and see what happens.

    I’m glad I didn’t fry it but wouldn’t shed many tears if I did. They have parts for that. :)

    Put a Stihl chain on it and ran another two tanks of fuel through it. Starts first pull every time. Running smooth and oh so quiet. Must be that catalytic converter in there.
    Part of me wants to tear that out. The other part has always thought it’s nice to have one quiet saw for working in neighborhoods. We’ll see.

    And cooler but you will need to retune it a bit richer- 510 and a whole lot of other saws are coming down the pipe leaned way out to make EPA regs adding extra oil only make problem worse. If you can find some non ethanol gas- that by itself will knock the heat down a bit. when the 510 first came out ( tuned way lean oem there were a lot of then that got seized up after a couple hours of use. quite the hue and cry about that at the time. but no different than some other makes suffering the same fate for the same reason.

    Yes I learned about the extra oil causing a leaner condition last night. Did not know that. Ran like a champ on it though. No sign of excess heat. Went back to straight VP 50:1 for the second tank.
    I also read about all the saws with epoxied carbs ets etc. mine has three screws. Looks like single D screws. Gotta find an adjustment tool. Or make my own.

    Ran another two tanks through it. Gotta say it’s a boring saw :) eventually I’m gonna tear apart that muffler and maybe even try my hand at porting it a bit.
