Hahaha, I am just no expert with engines, but since you corrected my name, I'll share my experiences ...  :giggle: :giggle:

- use the starter only when everything fails, use a chicken stick. Learn to manage the frustration, then every successful start is rewarding
- right amount of fuel in the chamber to start, 'itna sa' fuel is more than enough.
- these sized glows take about 4 litres (not four tanks) of fuel for properly breaking in before they can really deliver good power.
- run one click rich from what one thinks is correct. running really rich will destroy plugs sooner than one expects. Keep spare plugs
- During break in, give the engine enough, like really enough fuel so it four strokes and let it burn one tank on low throttle while 4-stroking. it's tempting to go full throttle on new engines
- If the engine is tuned correctly, a little flick is enough to start it. for tuning, 'listen' to your engine. Every flying session needs a tuning because of weather/humidity. I try to keep the engine head temp around 210-220 C.
- eliminate problems in this order, engine temperature > tank plumbing + backpressure > no fuel/flooding > throttle settings > idle settings > mixture settings (HSN) > glow plug > fuel quality > LSN
- use pinch test for LSN
- engine starts and dies down?, if repeat pinching the exhaust helps, the engine is running lean, if pinching fuel line helps, its running rich
- start lots of engines, stop them, re-start, get some scars on fingers. Never give up, be at war with the engine. And then when it just doesn't start, give up and place the blame on the engine, curse the engine if that helps. Try again after sometime.
- give full throttle right before take off to get things in order (I always forget this and then have to walk up the plane with an engine that just quit). This helps cleaning out engine and also brginging the engine to the correct temp
- all engines quit and they will quit when you want them most
- talk to people on the field about the problem, seek help

I still have my days of quitting engines  ;)

You forgot to add: make sure your fuel is mixed and stored correctly  :giggle: :giggle: :giggle:
