OFF TIMING? No Start

[nick956]

Alright so I replaced the head gasket my my baja 90 and upon doing so I think I may have thrown the valve timing off somewhat. I currently try to start it and wont but also can here like a hitting sound and doesn't sound like before. Can you'll help me getting it right? Also I did not mess with the flywheel chain or anything in the rear only the front cam sprocket.

Your timing is definitely buggered, Get a manual and find out what your timing is supposed to be set at. It you hear a knocking DON"T continue to crack the engine or your gonna destroy your values.

I don't know baha's, but i would hope nothings physically interfering inside that motor. open it again and recheck your work

I opened the head again and found that the lower exhaust valve is hitting the piston which definitely mean timing off and I will try to search for it. Hopefully others can chime in with manual help. Thanks

I'm sure the valve is bent. Try lapping the valve if it looks straight.

Whats lapping?

making the valve and it's seat to match up perfectly
(basically slowly grinding the valve in)
