Hey everybody. As the title implies, I'm looking for some advice on my 350. Unfortunately it was straight gassed a few years ago by yours truly with very few tanks through it. I commited the ultimate sin of saying "I'll put the oil in the gas when I get back." Yeah, that didn't happen. I was so pissed, the saw got put in the corner and left untouched for a LLLOOOONNNGGG TIME. When I finally pulled it apart a couple weeks ago, I tried to clean up the jug and found enough damage to the 44mm jug to warrant replacing it. I researched all the options and decided on going with a base gasket deleted 353 rebuild vs going full 346xp. I jumped online and ordered a Hyway 353 kit with a pop up cylinder. This is my first time rebuilding a saw and I figured I'd clean up the intake and exhaust ports and clean up any casting flaws in the transfers. Just to dip my toes into the porting/polishing stuff without ruining anything. Things were going well until I realized a BIG difference between the jugs. On my old cylinder, the impulse port on the jug goes through the cylinder leg. On the new cylinder, the impulse port exits just outside of the cylinder leg. The port would end up sealed up where the cylinder riser and jug come together. I researched the heck out of the 350 to 353 conversion and don't remember reading anything about this type of situation. Any advice is appreciated.
