What are the rules for muffler for this saw Scott?
factory muffler with 80 present of the front intact, I think is what it is
What are the rules for muffler for this saw Scott?
so ur saying why the dead spot in between transfers, even tho the bridge is only a couple mm wide?
Hard to tell from pic, are the roofs of the transfers flat or or are you trying to open part of the primary first, instead of all at once?
Trying to guess exactly where the piston sits in the bore, it appear that both front and rears are purging on the exhaust side of the openings.
The extra long trail on the rears, makes it appear that they have more velocity, open first?
The bridge is very narrow, yet there is quite a large space in the wash pattern.
I’m pondering why this may be...
your starting to see what I see, yes why.
That you'll be adding some JB weld to the outside corner of the upper primary's...?
Well first your previous post says the primaries open first, which means they should have the initial burst and thus more velocity..., so I’m wrong in that...
What I see is that possibly the mains need more taper toward the intake, they appear to be crashing into the wall and diverting more towards the center of the cylinder. Not really any room to bring them back though. Bridge is too narrow.
I think so
primary's and mains are the same thing, just a different term, port nearest the ex.
there's turbulence in the port causing the fresh charge to go straight out the ex port. epoxy in the right place might help.
also opening the secondary's sooner might help
I was wondering if epoxy would hold up in that environment? I suppose it constantly cooled by the fresh charge.
What would an ideal piston wash look like? I’ve tried to make them even, but never really knew what they should look like.
