I actually do want to try this out in a work saw just to see how it does. But sooner or later im gonna build myself a cant racer
ya never know. keep intake as high as possible and it may work well im amateur level grinder and thinker so take whatever i say with a grain of salt lol.
True. And thats what I was thinkin intake wise. BUT... with all that opening up of the lowers, It would make sense (to me) to try a different carb. Im thinking of a Tillotson off a 281/288. Same body as a 266/268/272 carb but internally its different, same venturi size, same throttle/ choke throat size, can easily swap shafts too. Both impulses are fed through the block. You know whats funny, the Tillotson HS-298A, 395XP Carb, has the same exact venturi as the 272 and 281/288 tillotsons, but again, different game when you get inside of the carbs. Any ways, Im just going to try out a freaking carb LOL.
Hooray speed holes!!!!
Uppers need the roof flattened a tad more, just a educated guess. You want that pattern on the chamber to be on the piston. But how does the saw run? If she runs good I wouldn’t worry about it too much. All piston tops turn black from carbon after a while anyway, which is why wash is tricky to read. You gotta run it hard for a few tanks then read the wash... then the two stroke oil can also play a role. Some leave wash quicker than others. Interesting stuff for sure.
Wash looks neat, but im guessing your mains are slightly aimed to mid or more to ex? And traces of charge escaping slightly through the exhaust? You can clean up the carbon and run the saw hard for few cuts to make sure
It runs pretty good! Ive always found this “reading wash” thing interesting as well.
The mains on that 359 cylinder were aiming towards the sparkplug hole, towards the intake. But they could have gone a little further and maybe a little flatter tooWash looks neat, but im guessing your mains are slightly aimed to mid or more to ex?

Here's an example of what happens when main is aimed too much to the middle

Nice work Austin!
Thank ya Dan. Its not done yet though. Ill upload smore pics soon
Looking really good there Lil buddy (even though you’re bigger than me).
Not sure if its the camera angle or what, looks like not more than 10~15 degrees from exhaust roof
Yeah blowdown is kinda short (16*). Just for testing purposes
.
Tanks Doc. Hopefully she runs better than last time.
You know what?Yeah blowdown is kinda short (16*). Just for testing purposes
