My question is I can't keep it running thru 1 tank completely......It wants to stall after about 5 minutes of run time!!!

I have a fuel filter on her ...Do you think there is a airleak or that during break in I just did not get up to full temp onle ab out 140 or 150 before it would die!!!

any help would be great !!!

thanks John

Do you do the post break in tune?? Usually have leaner needle settings...

yeah dog .......i purchased a dial tune and have made some minor adjustments!! but nothing radical....but breakin I have not gotten temps up to high !!!! like i mentioned earlier just 140 to 150....

just wont stay running!!

also using traxxas 20 % fuel.......should I switch to something else or is this fine??

what are your temps now? And %20 is fine. you should be running temps around 220-260, if your temps are lower then you still need to lean a bit more.

This might help!!

good luck

Maybe try a new glowplug (or a different brand). I've found that my truck stalls more often as the glowplug wears out. Also make sure that the fuel tank lid is closing properly. Mine stopped seating correctly, which caused stalling when I would land from a jump. I replaced it with a o-ring from a cheap multipack and the stalling-when-landing problem is gone.

is the temps in celsius or fer? if cel then i think its too high, in fer then way too low.

I assume that the temps are F and not Celsius. As TRD has mentioned your temps are too low and you're most likely still too rich. Befor you start leaning it more tho, try and run it harder first. It sounds like you may be a little timid with the throttle still. If it's broken in (which according to what you wrote, it should be) you will be fine. Give it some juice. Bring that temp up and then check and see if you need to lean it out a bit more.
Also, don't forget that you have an idle adjustment and low end needle as well. Your low end might need to be leaned. I've noticed that some don't pay much attention to low end and idle, that's all.

Traxxas makes a good fuel for RTRs btw, so you can just stick with that.
