black widow trouble
 

i am trying to start my black widow but having troubles. when i put the gas in, it seems as though it is just coming on through a cack or something, but not to sure. whne i put a few drops of primer in it sometimes the engine runs 5-7 seconds then dies. i do not have the direction to the plane so i do not know exactly how to start it so here is what i am doing. I first just fill the tank, attach the grow plus, put a few drops of gas in the piston then turn the perpeller. See anything wrong?

A) it could be flooded

B) Make sure you turn the prop counter clockwise

You could have a pin hole in you fuel line. Do you have a pressure line going to you exhaust???

Check the 4 screws in the back platte, they may be loose or the gasket between the platte and the tank is bad or missing.
ej67 fuel line and exhaust!!!:eek: not on a widow!:D

aomwtimwes=sometimes
typing in the dark=bad idea

Did you check that back platte if it was loose it would let fuel in to the engine through the reed valve . If it still is flooded close your needle and crank it over with the head off, then put it back on and try again. Be very very carefull if you take the tank off and not damage the reed valve and gasket.

Turn on the lights before you work on the widow:D:D

I'm still wondering what a "cack" is? Couldn't find one on my engines part list.

He must misspelled the word? I noticed he spelled plus instead of "grow plus" but probably meant glow plug?. Must be a misspelling error? I

OK, that's enough. Fast typer w/o spell check. Let's leave him alone from here and just try to help.

platte.whats this, is that the clear plastic thing?

Samp.

First of all make sure the engine is ready to run. If the engine is new then It's probably assembled correctly. Snug up the four tank to case screws and snug down the glow head.

After fueling open the needle four full turns, turn the prop so that the piston is completly blocking the exhaust ports on the cylinder. Put 1-2 drops of fuel at the exhaust port. Hook up the glow clip, engage the prop onto the starter spring, wind one turn CLOCKWISE and let her go (The prop should spin COUNTERCLOCKWISE). The engine should start. If not keep flipping it untill it does. If the engine only runs for a few seconds open the needle another 1/4 turn and try again. Once the engine starts it will be running rich. start leaning (closing) the needle untill max rpm is attained. Continue leaning untill the motor starts to loose RPM, at this piont the engine is running too lean and you need to open the needle untill the rpm's pick back up and the engine is screaming. Once you've reached this piont open the needle 1 or 2 more clicks and she's ready to rock. Cox engines essentialy need NO break in.

With 1/2 A engines fuel is important. They like the nitro! 20% to 30% and at least 20% oil, and at least some, if not all, of the oil should be CASTOR oil. This is very important. If you need further help post ypur questions in the 1/2A forum. There's a great bunch of guy's there who run these engines all the time
