Hello folks,

I have a tower hobbies .46 Trainer RTF. I have run two tannks of fuel thru it, however, it seems that it may be running too rich. Im not experienced in understanding it, but, it seems to be spitting out too much oil from the exhaust. I have had to put down an old saddle pad to keep it ffrom turning my work bench into a slip n slide. The instructions said to turn all the way in, and then 3 full turns out. Which i have done, but its still running to rich. I would love to hear some tuning advice as my first flight will be on tuesday (weather permitting). Thanks in advance.

Your instructor will help you get it dialed in. It's not at all uncommon for a two-stroke to put out quite a bit of oil, so what you're seeing is normal.

First off, you are suppose to get oil spitting from the exhaust. Second Mount the engine in the plane and take it outside on the ground. The oil will cover everything in the workshop. There are several forums that cover setting up an engine.

To set your High speed needle, when you go to full throttle, pinch the fuel line and you should get an increase in rpms before it tries to die. If you don't get an increase you are running too lean and that is what kills engines.

You still need to run a few more tanks through it before it is ready to fly.

After a couple more tanks you will need to start setting the low side needle. At idle do the pinch test and it will take a few seconds before it will raise in rpms, Best setting you will get a little raise but not much. After you get the low side close, go back to the high speed setting again.

You should have a decent transition at this point. Now throttle up and lift the airplane and point the nose straight up for 10 to 30 seconds. It should not try to quit, if it does your high speed needle is set too lean. Richen it up a little and try again.

After this you should be running reliable enough to fly. After you get close to 1 gallon through the engine, go back and fine tune the low side needle and high side needle again. Also check the high side needle before you fly every flight at the beginning, and after it breaks in, at least once every flying day.

One other thing to mention. These things get away from you fast. Go to a local flying field and get some help learning. You should be able to find a local field either here on RCUniverse, or go to the AMA site www.modelaircraft.org While you are there go ahead and join.

Thanks for the advice, Much appreciated
