juanes,

Good luck with your engine. I haven't had mine long enough to have had any mechanical troubles with it, carburetor or otherwise.

Mine needed a surprising amount of fuel...lots of choking, to the point that one could easily smell gasoline.... and lots of air i.e., fairly open throttle, to start. It needed more fuel and more air than the instructions seemed to indicate that it would.

My engine has about a gallon through it now and, even when warm, will oftern require the choke, flip; open choke, flip routine to restart.

Interestingly, to me at least, I have never been able to flood the engine. This is true even when re-starting a warm engine. Flooding was my primary concern when first getting the engine to run. Maybe there is something wrong with my engine and I don't know it!!

Let us know how you progress. rlmcnii
