2 problems need help

[freeflyn2001]

Just fired up my Nitro for the first time. 1st I had a clicking coming from the boom so I reversed the t tube, I had the bearing toward the tail I thing that was wrong according to Finless vid "i think" now the bearing is more toward the front, And it still clicked a little but not as bad Is this normal." 2nd problem I have is the engine is loading up, causing me to remove glow plug and crank it over to blow all the fuel out. I am keeping the throttle at low stick until it starts cranking, sometimes it fires other times it loads up so bad it wont even turn over, I am running os 50 hyper---about 2 turns out
mp5 muscle pipe

Any Ideas

I believe your tail clicking might be your tail grips rattling around. Do they rattle only at an idle? It does that on my 600n.

Your engine loading is perfectly normal for your neddle being at 2 turns out. You might want to lean it to 1 and a half truns and a few clicks rich. Your engine locking is normal for your neddle setting too.

It was rattling as I was starting to spool up, never went more than 1/4 stick. Is 1 1/2 turns to lean for break in.

loosen the tail boom mount and JAM the boom in until it engages.
don't try to fly until you do.
Your idle mixture is too rich, start around 1 3/4 turns, idling only and adjust the idle offset cam until you can pinch the fuel line, have it maintain RPM for a second or two before speeding up, then richen the main to wherever you like.

I thought I had the boom seated all the way I will check again tomorrow, Which way should I turn the cam bolt CW or CCW.

Turn the camscrew clockwise to lean the idle. 1/12th of a turn at a time. It may end up near the 2o'clock position....or at least that is where mine ended up to idle well. Also, because the full tank of fuel has a level HIGHER than the carb, it will drain off and flood the engine while you are trying to start. Leave the fuel line pinch clamp in 'pinch mode' (if you will) until just a second before you spin the starter motor. I find it easier to get the motor spinning first, then release the pinch clamp while it is spinning. Your buddy should already have a hand on the rotor, holding still.

when you think you have the boom seated, push harder! It will likely move another 1/2 inch.
Clockwise, and if possible turn it when its running and follow the pinch directions above.

hey I kept loading up and kept loading up with oil also on break in, I was told to lean the main needle I,m at 1 turn out and 4 clicks now at 36degrees, also if it wont start see if its fuel or oil if you've ran for a few minutes, my mp50 held oil and it went back into the cylinder when I shut off. Start with glow plug real loose and seperate ignitor on then tighten with ignitor
and follow up with wrench after started, this solved my problem, I also put a small loop
in the fuel line upward to stop the fuel flow to carb when off. Saturday I installed a fuel filler
valve where the aux glow plug hole is it works excellent, like filling a car no clamps no loops and no problems.

"Start with glow plug real loose and seperate ignitor on then tighten with ignitor".....

I am sure this is not a good idea. Things do happen with a loose plug. It is hard on the engine and the plug can and will launch like a bullet if the last thread or so decides it can't hang onto the plug. I saw a glow plug vanish last summer with a loud POP sound, just after a friend started a plank. Launched straight up and luckily missed us both.
Doing this also adds something else to the 'oooops, I forgot to tighten that back up'....catagory, resulting in a crash.
I would use other methods to clear the engine.

I would appreciate knowing how else to do it, I was just passing on the solution that worked
for me, I had already taken pipe off and drained it and reset needle, this got me flying that next day, after of course trying to remove plug run starter until clear, reinstall plug only to lock solid again.

You were on the right track before, just don't start the engine with a loose plug. If the engine is flooded, remove the plug, open the throttle and spin the starter motor for a few seconds. Maybe even tilt the heli so the muffler is on the high side while spinning the starter motor. That way any collected fuel or oil in the muffler will re-enter the engine and exit through the plug hole. Worked for me anyway.Have someone hold a rag at the plug hole to stop a mess. Then heat the plug with volts before you put it back in to make sure it's not drowning in fuel.
Keep the fuel line pinch clamp pinched at all times until you have the starter motor engaged in the socket and ready to spin, then release the clamp. A full tank of fuel will flood your engine in seconds without the clamp. Notice the fuel in the upper half of the tank is HIGHER than the carb. That half of fuel wants to go down hill and 'beer bong' the carb. Also, watch when you fill the tank. Even though no fuel will go into the engine at the carb, if pinched off, it sneaks in via the pressure line that goes from the top of the tank to the muffler, where most fuel gets into the muffler, then chokes up, locks the engine...you never saw it go in there. Fuel the tank to almost full, not full to the top, or you'll start this process all over again.

I talk too much.:roll:

Damn I hate when this happens.

[WayneBrown]

glad to help.
Which problem did you get sorted?

[freeflyn2001]

Both problems are solved thanks for all the Help, on this

[jbock24]

Engine starting and your solution worked, I have two gallons through the 600 now
