.46 strage things...
Hi man, Today i made another step forward for the hard job of tuning this beast... I have only some question. I tuned it lean cause I want it to pull really hard on the terrain, and a good quantity of smoke come from the exaust, to make an idea i've locked the central differential with a 500.000 oil, and it wheelie every time i pull the trigger. Wverything should be ok, but i don't understand a couple of things:
- It idles irregular, high, low, high, low, until it stalls after 10 seconds, or (not everytime but 2 times on 3) stalls without the irregular issue when i stop the truck. it's not a brake/servo issue. Then, when i restart the engine a second time, the engine is uncompressed, like it has got no mixture! after a couple of pull it compress very well and start without problems, so i think it's not a temperature issue. i've changed the entire fuel/air line, with a filter in the fuel line and a empty fuel filter case between the muffler and the fuel tank (like my LHS tond me to fix the half tank issue)...
- it seems to go outrange (sorry for the bad translation...), it seem to go high RPM when i pull the trigger half, it is strange, RPM raises, but not the power...
I've to tell you that i cannot tell you the engine temp because i'm waiting for the infrared temp indicator (with the complete roll cage), i'm running a 25% nitro with a #7 plug. Engine has got 2 or 3 liters.
Can i ask you an another couple of things? i've an Optic 6 and an electron 6, it seems that when they are near the servos go crazy. why?
How are the Spektrum radios? i was thinking on changing my radio equipment because of that issue...
Thanks man for all the replies, please help me with this hard job!!

Actually guys, its not an empty fuel filter, its an ONFA fuel filter and primer installed between the tank and exhaust.

BTW: Once you fit the valve you will have to retune your engine(lean out the high side alot, I think I had to turn mine in like 3.5 full turns. And then lean out the low side to control the idle/low end circut)
