Problem 2.
The engine starts after being choked but then stops soon after.
Solution:
The low needle on the carburetor is probably too lean.
Adjust the Low End needle until you achieve a smooth idle and a reliable
transition to high throttle. Generally if the motor stutters or coughs in the mid
range or when the throttle is advanced, the low end needle is too rich and
possibly even the high end needle.

The engine runs rough and is vibrating strongly.
Solution:
Balance the propeller. Check the ignition timing. Check your plumbing for
air/fuel leaks
Check your spark plug for carbon and check the spark plug gap. Check the
motor mou
be sure it is rigid. Check to make sure the engine is mounted on a level surface
so that
crankcase is free of tension. Check the engine and propeller bolts.

Solution:
Check:
A. The carburetor settings.
B. See if the propeller is too large.
C. see if the engine is overheating.
