I have a COX queen Bee .074 and i cant get it to turn over...?!
I have cleaned it thoroughly, bought new glow plug, new fuel, new starting battery and i cant get it to run for more than 30 seconds. I think it is not getting fuel. it wont draw it on its own. what kind of gas tank/fuel hose setup is best for this type of engine. I am using a 3 port gas tank, 1 filler (capped) 1 breather( i have it routed to the muffler) and 1 going to the engine.
I cant figure it out..
Thanks, Matt

Is your fuel tank at the same height as the needle valve?

Welcome to the fold. It's not always this frustrating.
A few suggestions,
1). Make sure the tank centerline is just below the needle valve, as veiwed from the side.
2). I know Cox gives a recommended needle valve opening, but try this- remove the needle valve completely, cap off the other lines, and give the tank a GENTLE squeeze. Fuel should come out of the needle valve opening, if not check for obstructions.
3). Remove the needle valve, and soak the engine in alcohol overnight.
I have run several Cox engines in the past and a few of them had congealed fuel (or something) in the needle valve/spray bar/reed valve.
Finally- open the valve to the setting recommended by Cox, and them open it another 1/2-3/4 turn. I have had them run at 2 1/2 turns just fine. (Needle was actually to long- I measured it).
HOPE THIS HELPS!!

thanks for the tips. I removed the carb, cleaned it thouroughly, removed a clog from the fuel inlet, and it started right up! I also flipped the carb around from the stock position, so the needle is on the opposite side from the muffler.
I can get it started every time.
----only, now i cant run it... my neighbors in the apartment building are sleeping!

Thanks again
Matt
