Hey guys,
I posted earlier that I couldn't fit a feeler gauge in for my valve check. This all came after removing the camshaft and sprocket to replace the sprocket (goodbye aluminum sprocket... hello steel).
I was very meticulous in my work but is it possible to put the camshaft 180 out? Its a single cylinder which leads me to believe that it is NOT possible to do that but here are my symptoms:
1. My exhaust and intake valves are unloaded at the same time ONLY after the exhaust valves close while cycling the engine through its 4 strokes with the kick start lever.
- My understanding was that this should happen only after the intake stroke
2. After my exhaust valves close the piston does a full "up and down" cycle (down all the way then up all the way) before the intake valves are compressed.
- I thought that was what was supposed to happen after the intake valves were enganged (intake valves open, piston goes up for the compression stroke, down for the power stroke, up for exhaust stroke right?)
3. When turning the engine (cycling it through the 4 strokes) via the kickstart lever the exhaust valves engage IMMEDIATELY after the intake valves close. After the exhaust valves close (as mentioned in number 2 above) the piston cycles up and down again before the intake valves are opened.
I may have just looked at this for too long and begun second guessing myself but it seems as though the intake valves are opening when the exhaust valves should and the exhaust valves are opening when the intake should... aka functioning backwards. This leads me to believe that my cam is in 180 degrees off. I just didn't think that was possible with a 1 cylinder engine.
Any thoughts... my brain is failing to work properly at this point!
