What am I doing wrong in the start up procedure. Fill my tank, open the throttle a wee bit, put thumb over carburator and choke it. Once I see fuel I stop, put on glow plug and try and start it and it seems as though there is an hydraulic lock. I remove glow plug, turn prop and I can here bubbling which indicated flooded I believe...anyone help please. I am going to have a stroke...

Where is your tank located with respect to your engine's carb? The center line of the tank should be at the same level as the center of the carb. If it is much higher, you can get flooding.

If you burn the fuel out of your engine at the end of the flying day, as you should.....Then you only need to prime the engine on the first start attempt of the next flying day....Any priming after that will lead to flooding.....

I'll tell you how I prime my glow engines.....after I have checked the control throws...with the glow stick still off....I open the throttle wide open, and like you place my thumb over the carb. I turn the prop in the direction of rotation by hand until I see fuel just get to the carb...then another rotation.....close the throttle flip up throttle cut to run or adjust trim..attach the glow stick and start using an electric starter......

Hows your glow plug?...you might want to check it...you're looking for the whole coil to glow not just part of it and it should be brighter than cherry red......

loet us know how things work out for ya

It can be several things, tank location is the place I usually look at first, too high like Brr mentioned is usually the number one cause. If the plane has been flipped upside down or stood on it's nose can be another one. Like Jet mentioned, other then the first start of the day is pretty much the only time needed to choke. If you are using an electric started you don't really need to choke anyway. OS four stroke engines used to come with a choke attached to the engine. OS figured most people today are using electric starters these days and no longer install them. You can also roll over the engine with your finger over the exhaust to choke, not as fast as using the carb but it works.

Do you leave the fuel tubing attched to the Carb when you fill the Tank? How many lines to the fuel tank and where are they connected? and which one do you hook the fuel fill lin to?
