    Sweet. I'm still trying to find a bow bar to use.

    I like the clutch cover with the built in guard, Poulan certainly was well in tune with bow bar operation.

    I would say pretty much so. A lot of the saws like the 71A in my signature were set up so it was simple to go from straight bar to bow and back. That said the 200 and 300 series saws were a bolt on as well but it took a whole kit of parts to put the bow on it. It has to have special bar spacers, clutch spacers, handle bar bracket, handle bar, clutch cover, bar nuts and had to switch the bar adjuster from the case to the clutch cover.

    Pretty hard to find all the parts needed now days to complete a bow setup on them.

    Was told tom repost here.

    This is my One Grandpa's saw. He had bought it from my other Grandpa who was a Homelite dealer in the late 40's so it's a double sided memory saw. Time to fix it up.

    [​IMG]

    This was why my grandpa stopped using it in the 70's. The sprocket had broke and they were not available. Internet now makes it possible so I finally found one and ordered it.

    [​IMG]

    Did a quick compression test and it has nearly 120 psi so it should be okay. Luckily it wasn't frozen and I put some oil in at first to lube the wall up. It's been a long time since it has fired

    [​IMG]


    Checked for spark and it was fine. Poured gas in the spark plug hole and it hit right away. Couple more times and same thing. Lines seem okay but probably carb needs cleaned and maybe diaphragms. Started taking it apart.

    [​IMG]

    Most of the time you don't have to take them clear off to do this. Just blowing and checking things out and it makes a nice holder when it's on the saw. been a while since working on one this old.

    [​IMG]

    Went down to Grandpa's parts stash and dug through the carb parts and as luck would have it I found the exact diaphrams and gaskets I needed! SCORE! Old ones were brittle and cracking.

    [​IMG]

    Put some more gas in the cylinder and it fired right up and ran. Put all the stuff back on and it's now good to go. Gave it a quick clean as well.

    Check out the recommended 10:1 mix ratio. Enough to keep mosquitos away!

    Not a perfect saw but a nice survivor and memories for us. My Mom's dad bought this from my Dad's Dad before they were married in 1958 so this Double memory saw is a keeper for sure.

    For those of you who don't know the model number 4-20 means 4 HP and 20 lbs

    I'll tell you again here that you did a great job. Your bow looks like the narrower one.

    For information on the difference between bow saw and the narrower one is Homelite called the narrower one a clearing attachment. It was not a bow saw.
