A problem on the very small outboards the are either hard to start or will not run at idle is poor crankcase compression. This likely due to worn crankshaft bearings (bushings). Check for lateral movement of the flywheel, any discernible movement would indicate worn bearings. This condition not easily remedied, absent a competent machinist. A possible "band aid" , try running a very rich oil mix, like 8 to 1 and see if the condition improves.
