Mike:
I´m having trouble starting my engine, it has never been easy to start from the beginning, but it´s getting worse day to day.
I have checked the carburator, cleaned it. It only had a small amount of dirt in the screen inside it, so I got a filtered intake for it hoping it would help, and the problem is still there. The spark plug was changed for a brand new one, the ignition does send a pulse to it.
My starting procedure has changed but here are the two procedures I have tried:
1.- choke on, full throttle, ignition on... flip until it fires and dies again.
then choke off, throttle at idle, ignition on...until it runs

the second procedure is the one that is stated in the instruction manual

2.- choke on, full throttle, ignition on... until gas gets to carb
then choke on, full throttle, ignition off... flip 4 to 5 times
then choke off, full throttle, ignition off....flip 4 to 5 times
then choke off, high idle, ignition on... flip until it starts

I both cases the engine starts for 2 or 3 seconds and then dies. I have to keep fliping and fliping the prop, choking it, un-choking it, and the engine starts and dies. eventually, the engine will start and run normally, but it takes somewhere between 40 and 55 flips to start it.

The tank has been re-lined 3 times, and has been tested for leaks. and everything is good there. the battery is a 6 volt, 2700 mAh Expert brand, and it barely loses mAh or volts. After 5 fights the batt, is till at 6.5 volts and when recharged it gets to max capacity with only about 450 mAh. so there is still a lot of capacity in it after flying.

Is there anything else I should check? Any comments are appreciated.
