It sound like its running really rich

Super rich! Lean it out just a tiny bit and try it again. If it is too rich you can't keep it running long enough to break it in! There should be lots of smoke and even fule coming out of the exhuast during break-in. Good luck and take you time!

kevinRC

i would ahve to lean the low speed needle valve??? right??? or high?? or both??? i hope thats it...cause i dont want to mess anything up.....

anyone else have any suggestions???

WSW-WYATT-EARP

just your high speed valve ... for now

kevinRC

can u please explain that to me??? thanx.....

wouldnt i ahve to lean the low speed needle valve?? because that controls the idle and begining throttle??? sry i just need to learn these things....thanx

jefx

The high speed needle (HSN) controls the total amount of fuel to the carb, so by leaning the HSN, you are also reducing the fuel flow through the LSN (low speed needle).
Just lean your HSN by about a 1/8 turn, that should be enough to keep it running. If not, go another 1/8 turn etc. Just make sure you keep it rich enough for proper break-in.

wut if the engine continues to stall?? wut should i do next???

overrev

Low speed needle controls fuel flow when idling.High speed needle controls fuel flow as you open up the throttle.I have that engine in my x terminator. If that is whats happening adjust the low speed needle 1/8 turn .hope this helps. Mike

ok thanx guys!!! just wanted to make sure i was doing it right....ill let ya know if that fixes it......thanx alot

kevinRC

hi i was using my mammoth today....((thanx guys...leaning out the highspeed vavle fixed it....)) but something else started happening...

the "connection" between my radio and reciever started to stop. I would have to shut off the reciever and then turn it on again and then it would work for about a minute then turn it off again ect.

but then the last whole tank i ran through it, it really did not do it anymore with the body off....but it did it with the body on it... has this ever happened to u??? should i be worried???


thanx guys!!! the think is really sick!

It may be radio interference or bad batteries. Get a failsafe for your beast and a throttle return spring. these items are a must for some what worry free bashing.[8D]

kevinRC

yeah but the think is......when the engine was turned off, the radio was fine and did everything at the right time........while i was running the engine, and tried to turn or give it throttle, it would like hestitate to do it or not do it at all.....is this possible????

R/C Madman

My Feedback: (1)

Anything is possible!LOL Check all of your connections (linkage and wires). And just to make sure you did not get it wet did you?

kevinRC

nope....i havnt had it in the wet.....hummmmm

R/C Madman

My Feedback: (1)

I would check the simplest things first like the connections and change the batteries. I have had the same thing happen and it was bad batteries.

kevinRC

well in the begining.....wen i was putting the antennea through the plastic peice i pulled it so hard i ripped the antennea about 1/2 inch from the top...im not sure if any wire tore off...but would this cause the problem??? i hope not

R/C Madman

My Feedback: (1)

It can but, usually it would only effect the distance but, I could but wrong.

LEAN IT OUT A BIT IF YOU SEE SOME OIL COMING OUT FROM THE PIPE DONE BE scarrred ITS NORMAL LET THE TRUCK IDLE A BIT IF IT STILL CLUNKS OUT LEAN IT OUT A BIT BUT DONT FORGET IF YOU RUN THE TRUCK TO LEAN AFTER BREAK IN YOU BE BACK HERE LOOKING FOR A NEW MOTOR[:'(] ALWAYS RUN IT MORE RICH THIS IS AFTER BREAK IN AND AFTER THAT GO BASHING WELL HAVE FUN AND ENJOY[8D]

kevinRC

if i got a new reciever, it would come with everything new right liek reciever, and wire and everything? or just the radio???

R/C Madman

My Feedback: (1)

Yes it would have a new antena wire on it! But I would have someone that knows what to look for look at it before you start spending money that you may not need to spend. Have the LHS take a look at it first.

kevinRC

ive been thinking...could it just have been the vibration of the engine shaking and loosing the wires and loosing the connection????

R/C Madman

My Feedback: (1)

Sure it could. I have had one run of on me because the battery wire had a cut on it and it grounded out on the chassis. Check all of the connetions and make sure there all good.

kevinRC

i did yesterday....taped everything just to be sure....and the thing was sweet wen i took it out....put about 4 tanks through it already so hopfully i can start pushing it....i want the thing to hit 2nd gear....lol

R/C Madman

My Feedback: (1)

4 Tanks is all you have put in it so far?? If this is true then take your time. Don't push the break-in. An engine that is broke in right will last allot longer and run better then one that was pushed through the process![8D] I know it's hard to wait but it's worth it! I put 10-12 tanks through mine before I start pushing them and I still run them on the rich side as the engine last for what seems like forever!
