Top end help

[coon]

I ended up leaving my gas valve on while pumping non mixed gas in my tank than mixed it becasue i didnt have a can after being pissed off that my mom wouldnt drive me gas it totally slipped my mind when i got to the station to shut the valve off now with my stupidy....the pistion locked at idle...i used mystery oil over night in the plug holes and tore the cases apart and freed the crank now when i start it... its a bitch to start sputters sometimes before it fires and wont idle like a sign of bad reeds so i pulled the dome off today and looked at the pistions they move freely i heard the knock on the right side of the shee looking at the cylinder walls the left has a nice score and the right seems to be fine....my questions are what else to look for what would be a good top end / upgrades while the top end is apart and what do i need to complete the whole job...Any info would help so much thanks for taking the time to read this!
