Hello guys

I got a problem with my Vspec. First of all i use in new plug OS P3 and in pipe of GRP 2053.

Everything was ok before a few days and suddenly the engine start to do the problem in the start,when i start him i give him to work without to do anything for a 1 min and later i give him to be a hot 90-80C.

after this i down the car from the startbox and start to drive and when i want to get a full-gaz the engine is scream and shut down.
with the booster the engine is not shutdown and after i give him a 2-3 full-gaz on the place with a booster the engine work very well.

s0z on my "good" english :\

Thank for all

Engine sounds like its too lean. Mostly on the bottom needle, thats why it shuts off. Most likely its too lean on both needles.

AERC8

You say me to close the main needle? [needle of the Temperture].

How many turns on both top and bottom? What is the weather like (Humidity, temperture)?

AERC8

I'm not remmber the turns but I'm very sure and can say you the engine is very "rich" in a fuel.

the humdity is 30% and the temperture is 24-27C

Have you checked for air leaks? How old is fuel line?

AERC8

no leaks that I see. and the fuel is a new gallon

Cool Power 30% Nitro 22%Oil

Maybe the pipe of GRP2053 isn't work with the engine? or i "fall" on a new bad plug of OS P3?

RBMike

22% oil???? Are you sure about that?

Cool Power is nitro for helicopters, and yes it does have 22% oil. You shouldn't be using that fuel in a V-Spec. Most car nitro has half the oil content.

It does sound like an air leak. Seeing that you got an RC8, check the tank to make sure it's not cracked or anything. Also check the exhaust seals (both the one on the exhaust port and on the connection). Also make sure the carb is seated well into the crankcase. After checking all that, go back to the stock settings for all 3 needles and start tuning from there.
