You must elaborate more. Dont just give very simplistic answers that everyone already knows, you must give details on how to correct these. Details such as:

#1) Air leaks: Check the carb fitting to the manifold-intake block, check the gaskets in between, always replace the gaskets whenever you take off the carb and its intake block, Check the exhaust pipe/canister, make sure it is bolted down all the way, always replace the gasket between the block exhaust port and the pile manifold, Check the cylinder head and make sure it is bolted down to the lower crank case pieces, etc.

#2) Wrong oil mix: Fore break-in go with a 1:32 mix, then progress to a 1:40 mix for everyday running once the engine is broken in, etc.

#3) Choke left on: Aactually, I would have made this #1, it is probably the most common simple mistake we all make in starting any 2-stroke gasser.


Dont give simplistic answers, you must give more details and actual solutions. You only gave problems, no solution on how to fix them. Giving too simplistic of an answer unfortunately makes you sound noobish (No offense intended). Give your knowledge on how to solve the problem.
