As i start its okay for few seconds,
then RPM drop to 1000 and it almost cuts off and vibrates like crazy,
then slowly it goes to proper idle speed 2400rpm
This video 10 seconds after cold start.
Warm start is same except that period of low RPM is very brief compared to cold start, and revving up usually fixes it.
What could cause this RPM drop?
P.S. Just installed new air filter before making this video.

Seems like i might have misplaced idle air intake hose for crab, i moved it in front of the carb next to the cylinder dunno how it made any difference, but now i placed it sideways as it was originally and re-adjusted idle speed. Will see if problem went away tomorrow.   |

Blue "carburetor overflow hose"

i had a very similar issue to this, was causing some weird jerky type stuff some times when i went to take off, couldnt get the idle correct etc... and it was a air leak my manifold gasket was messed up and so was the carb gasket.
