If it were mine and I didn't know where a vibration was coming from, I would first make sure the engine was bolted down tight, if it is, I would then remove the drive shaft to determine if it's coming from the front or the back.

Either button is fine... Finding out why the button is worn out might just be the answer to the vibration problem.

The button fell out and I can't find it. THe engine is tight. The carb is adjusted correctly and it is in time. The frame isn't broken. Thanks for the ideas I'll go check now.
