Ahhh.....no that was just some 3/4 birch plywood cutoffs that I used for packing.......junk.....
Junk boards eh.
OH #@*$! I really am going blind, from staring at carburetor parts.
This is from a pair of knockoff ZAMA C1M-W26C.
I've been trying to look them over, to pick the better one for my friends PP4218.
New carb and fuel line, etc, dialed in the screws and Saw cranks like it should now.
Buddy says "I've never seen it start up like that before"
And yes, it had been an Ethanol victim (until now!)
We put a 16" powersharp bar & chain on it also.
Been wanting to see how well they cut.
Wowzers. I've run out of drive space to edit pics,
but here's a few crops to, maybe, make up
for me derailing things earlier.
You'll see a problem I found in both carbs.
See how that cover and the body are not aligned?
The diaphragm gets that crease pinched into it as a result.
I tried to smooth the corner, without going too far out from under the ridge line on the cover.
Then I put a rubber diaphragm back, rather than that plastic one.
I think the rubber ones make for an easier cranking engine.
I think my friend also does now.
