This is a great web site for info. Just about everything I learned that wasn't in the manuals I learned from here. I would recommend using the search utility and looking up info on your particular plane, engine, and radio. Then looking up anything thing else that you think you might need. Finally, if you have a question, ask. Most of the time you'll get an answer withing an hour (two hours if the weather is nice).

And he be de man.

Mike B. MinnFlyer not only has the knowledge, but he will have diagrams and schematics to help us fledglings understand.

Here's a couple info pages on engines in general

Is you hunt around here on these forums you can pick up some incredible information.

I have a TT Pro-46 and I like it very much. It is my everyday use sport futzing engine.

Okay why after I filled the Tank up and tried to put the electric starter to it fuel came out the carb the muffler and anywhere else it could find and then the engine became to tight for the starter to turn it then the fuel ate up most of the rubber inside the starter.... Wow I am clueless when it comes to this... Maybe I should try needlepoint...

As I also agree that this is the best place to find the info you need...also try this out.

I used this a little when I first started (except I had the very old paper version). A lot of it is outdated and may be of no help, but give it a try anyway.

You flooded it.

The fuel is uncompressable. Once it has displaced the air in the engine it becomes very difficult to cycle the piston. (And overpowers the glo-plug's ability to ignite it). You could have snapped the piston rod. If this happens again, remove the glowplug and use the starter motor to cycle out the fuel (Tipping the engine if possible so it can slop out the plug hole).

Try starting it at 1/3 throttle.

You flooded your engine. The easiest way I found to clear the motor is to disconnect the fuel line, take off the glow plug, and use the starter to turn the prop for a few seconds. Be warned, fuel will come flying out of the glow plug hole. I was lucky, I had sun glasses on so I didn't get any fuel in my eyes, but my face was covered. I hold a paper towel over the hole when I clear the engine.

After clearing the engine, replace the glow plug and fuel line. You might also want to remove the spinner and make sure the prop nut is tight. If it's loose (and mine was after this happened to me) the next time you use the starter you run the risk of the prop flying off.

After you have checked the prop nut and reattached the spinner, fuel the tank. My engine came with a manual that specified initial needle valve and throttle positions for start up. The manual said close the needle valve, then open in it 1 and 1/2 turns and set the throttle at 1/4. WITHOUT priming the carb., else the electric starter to start the engine. Make sure you have a good hold on the plane. At 1/4 throttle, the plane will move if you don't have held down.

This method works great on my engine (OS .46 FX). It starts every time, the first time. When ever I, or my instructor, tries to prime the carb. by hand cranking the prop a few times, I always flood the engine and have to go through this process.

The big thing here is not to flood the engine or try to start it with the throttle closed; you will lock the engine and possibly damage it.

Hold your hand or drape a cleaning rag over the glow plug hole, because the fuel will spray everywhere while you spin the prop to clear out the hydro lock. Raw fuel in the eyes is a very bad thing, can be blinding.

Oops. Forgot to mention removing the fuel line. And as AdmiralHam says - keep your face clear.

The TT 46 needs about 2-1/2 turns open needle as a starting point. Screw the needle valve down closed (clockwise) and then back it out 2-1/2 turns. From there you will need to determine if it needs to be run richer (more fuel in with the air: counter-clockwise) or leaner (less fuel, less lubrication, too: clockwise).

I also had troubles starting mine.

I simply took my fuselage + engine to the field, and someone there had an electric starter, and even helped me break in the engine.

Take it to the field as is.

Glow Plug Washer....
 
Don't forget to take the little copper glow plug washer off of the engine before you spin it with the starter or you will NEVER find it in the grass.

Guess how I know that!!!! :rolleyes:

My recollection is that the TT46 is an ABC engine (or is it just the TT46Pro?). In any case, there is a somewhat different break-in procedure for ABC engines (having a tapered cylinder bore) -- short, hot break-in periods, rather than slow, rich break-in. Check this thread:

bridog, where are you in california? If you are having trouble starting it, you will have a lot more trouble if it does start. You should get with a club that can help you make sure it is set up right and help fly it. There are clubs on about every block there just about. Would be a shame to crash it.

Carefull cranking a flooded engine. As stated, you can bend the rod and ruin the enigine.

Screw the needle valve down closed (clockwise)
And when you close it, DON'T tighten it too much. You can ruin the needle valve.

Turn it slowly, just until it bottoms out, then open it 2 1/2 turns. (Or whatever your manual recommends.) ;)

I second the suggestion of finding a club and asking for help.

Good Luck, and welcome. It's a great hobby/sport!
