Sounds Jurassic-1 got it. The fuel has turned bad. It gets on the valves and just does bad things. Valve job time. Your this far its not worth the time to put it back on and do it again if it does not work out. Oh and drain the tank and put in some fresh fuel and then ad some fuel stabilizer. I work at a machine shop and we see this a lot on vehicles that sit. We have seen the fuel go bad in 60days.
