[QUOTE="lschultz745, post: 232250, member: 6696"] I just got a 2009 kx 65 that had a large gash in the cylinder wall so it only had about 50 psi compression and the stator coil was shot so it had no spark. So I bought a new stator for it and I temporarily filled the gash with jb weld and got the compression up to 80psi but it didn't start, and I only got some pops and bangs. So I bought a new wiesco top end and athena cylinder for it, but when I did a compression test, it had almost the exact same compression of 80 psi, however, it felt like it had a little more compression than before. So I cleaned out the oem carb that came with it, and now it will idle with the choke, and only rev up slightly before studdering or stalling. Without the choke it will idle temporarily for about 10 seconds before studdering and stalling. Thinking it was the reeds I pulled the oem ones and saw there was a small gap on the bottom pedels, so I flipped the pedels and made sure they sealed, but it didn't change anything. So I got new vforce 3 reeds for it from motosport, but that also didn't change anything. I also gapped the BP8ES spark plug from ~.24 to .50, .55, and .60mm, and did the same with a new BR9ES, but it also didn't change much. The timing marks are also where they should be, and I've advanced and retarted the timing to the other 2 timing marks and it still didn't change anything. Going back to the carb, I got 2 new chinese carbs from amazon and tried a 190, 200, and 230 main it them, along with the stock one, and changed the c clip to all the positions on the needle on each. I also adjusted the air fuel screw to all the positions I can, but with every adjustment, they all have the same results and same problems. I also tried new gas and different mix ratios from 30:1 to 40:1 with klotz r-50, but nothing changes much. I'm about all out of options and was wondering what you guys think.[URL='https://youtube.com/playlist?list=PL6InQSWnw2uGbI7DkrMTyXmvpBci_aBeK&si=WQvzBXQxa07LviTW'][B][I]Playlist of videos running[/I][/B][/URL].
