Ive noticed a little oil coming from the exhaust ports rear of the motor and plugs seen a little oily. I checked my manual for a setting for oil injection and is 1 mm clearance between the lever and post. Mine was over a 1/4 inch ?????? I took it in some to just under a 1/4 inch, there is no way this could be adjusted anywhere near 1mm ,any ideas about this ?
 
What is the complete model identity? Better still, the complete engine serial number.

What manual did you use for the procedure?

Is the correct thickness nut being used?

Has the link rod been messed with?

Is the connecting clip the correct one for your model?
