I can't figure which is the best way to fix the timing, on my 87' Samurai. My engine runs it just spits and pop, so I'm sure the timing is off. I replaced the belt and adjusted the timing and I'm still having the same problem. I don't know if I need to replace my crank shaft or if there is something else wrong with it. I tried finding an Adj. cam sprocket but theyre not made anymore. Any advice would be much appreciated.
