OK... this has just been noticed in the past few days...
ON a cold startup, the choke is on... the engine starts fine and runs perfect and SMOOTH... then about 5-7 seconds later, this 'internal' vibration starts in the motor....almost like a out of balance driveshaft vibe... but I'm in PARK. Then is goes away after about 30-45 seconds...hmmmmmm.
This doesn't affect idle rpms nor is it missing...just a vibe....
I'mm thinking thrust bearing.... any thoughts?
