    The crankcase needed to be resealed anyways so I figured while I was in there, might as well freshen it up a bit. Ring end gap before the replacement was more than 0.027.

    What should the ring end gap be? I've never had one torn down yet,so that's all new to me.

    ok heres one for you guys...ive searched..i tore it apart cant find anything.
    SDC carb kit done on a saw. 1 H 1 L, idles backed off, leaning the L i do not get a raise in RPMS, it just dies, feathering the throttle. When i richen the L to about 1 1/2 turns it gets fat/boggy and dies normal... WOT sounds ok at 1 turn on the High....i just cant get the L jet to react to stabilize idle.

    i did the tygon fuel line and grommet mod and full tank of gas, the see through fuel line only is half full of gas and the level goes down as i whack the throttle, the line doesn't appear to be pinched, the line should prime no? i read somewhere about a spring inserted in the fuel line.

    New 20" Oregon B&C for my Grandpa's old saw...
    Would've touched the paint, but I wanted to keep it all original.

    This is sort of interesting.. The saw pictured above, along with another saw I posted previously, had the same problem. When the saw would get turned clutch side down, the saw would want to stall as if it were being starved of fuel. On the other saw, I replaced both crank seals with no improvement. However, after I threw another SDC carb on (off of a 1010A that I knew ran fine at any angle), that saw began to run fine at any angle.

    With the saw above, I replaced the clutch side crank seal because it was leaking. Ran fine except when turned bar side down. So, I threw ANOTHER SDC carb off of a Pro 10-10 this time and now it runs fine at any angle!

    A lot of other threads jump right to the air leak/crank seal issue as the cause of this when this seems to be a carburetor issue. At least for my Macs. Does anyone know why some carbs have this problem with operating poorly at certain angles? Mind you, the carbs I've had issues were cleaned and rebuilt..

    It is possible that the throttle shaft is worn along with the bores where the shaft goes through the carburetor and it is leaking air. Seems odd that it would work on another saw though.

    I did have a problem with a 600 Series saw that lost power when you tipped the nose down, turned out the mounts were loose and then you tipped it down the throttle linkage did not hold the throttle wide open...

    Ed,

    Husqvarna got the MAC name when they bought Jenn Feng, China back in 2008.

    $25. Broken recoil spring. Low hours. Fired right up and runs great. A bit of a drive to pick it up but well worth it. Yeah, I'm a real sucker for these rascals.

    This Pro Mac 10-10 came to me from the local lumberyard, it was covered in sawdust when I got it and it also had a broken starter spring. Cleaned up nicely.

    I've never seen that air filter hold down before or is that just covering the knob? Nice clean saw anyways.

    As I said, it came from the lumberyard and someone use some locally available supplies when they lost or broke the original knob.
