Yestorday i was able to get it running. But today when i was about to start doing the heat cycles it wouldnt start for me. When i kick the kickstarter sometimes it will kick the kick starter back up. It sounds like it wants to start but then dies. Sometimes when it kicks back it will have some would call it smoke but i guess smoke coming out. I check the carb. Everything was clean. I checked spark its geting spark. I went looking to see if the sparkplug smelled like gas it didnt. So i tried just puting a little bit of carb cleaner in the cylinder to tell me if its the carb. It starts to start but dies. I moved the needle settling to the middle because it was at the very top. it has 120 psi conpression i tested yestorday. Could this kick back be a backfire or a kickstarter problem. Or could it be timming even tho ive never touch the timming? Or is it a reed or air problem. This project is sopposed to be a Christmas gift to my younger brother. And ive been figting to get it done before christmas its a surpise. Would like some fresh minds thinking on this problem
