Anybody know,
or have opinions, if the chrome loss between the exhaust and intake port on this 1111 series Stihl 075/076 will matter all that much?
It's a Stens POS "ceramic" cylinder and will go on a personal saw, not a customers saw. They really should be proud of that chrome lifting inside the intake port.
I would be using it with a new piston kit, and omitting the base gasket for Motoseal, plus tapering the damage minimaly from a broken ring above the exhaust port. The poor chrome crazing/cracking may have been the cause of the ring breakage to begin with now that I look at it better.
Will it cause an idle problem?
Maybe spitback spray backward out of the carb that eventualy soaks the air filter and chokes out the saw?
-Like a worn piston skirt can cause spitback when there is too much clearance on the primary compression, (the downward stroke).
Could any mixing of the exhaust and intake charge that might occur be enough to matter?
I know from personal experience that chrome loss anywhere on the cylinder wall above the exhaust port, or under the intake port, more than say, 1/4"-3/8"" from the bottom of the port, usually causes performance, and or idle characteristics problems on most piston ported 2-strokes.
The cylinder configuration is much like a bigger version of an 041 saw, with intake and exhaust pointing upward.
