You could well be in the wrong company here old chap.
These forums are driven, maintained and supported by folks that believe in the "if it isn't the biggest and most expensive it's crap" syndrome... newbees most of them.
Fortunately there re still a handfull of us that don't necessarily buy into that none sense... least not for non competitive flying.
The LA's are just what they where strategically designed to be... a simple, cheap, no brainer of a hobby engine.
Anyone that has problem opperating a LA engine must be a living example of the "no brainer" part of the OS strategy.
They work just fine. I have never seen or come across and engine that is just so happy under adverse conditions.
I have a first gen', day one LA.46... years old, that's in a fun fly. It's hit the ground crank first... onto concrete when I was learning to hover, so many times my ego has blanked it out!
It's used every sort of fuel, some with water, some with any old type of oil available and even some that didn't even have oil in it at all!
It's been in a lake, cover in snow, frozen in an ice clump, it's never been after run oiled ever... it's internals are full of rust... and it still runs f...ing great!
The secret is the running in part. Read the instrcution and al will be well.
Mind you, there a many paople out there that will tell you that those exact instructions were written by an idiot... be warned.
Enjoy your purchase.
