Need help tuning
 

Hi, Im new to nitro cars,i have a thunder tiger ssk and im having a problem tuning my carburetor (at least i think its that).When it goes into high revs the engine just cuts out, What could this be, thanks

welcome to rctech! be aware that more details will get more responses, which will help you. be more specific on what you do, and what you are doing with the carburator. it might be rich, but i cant conclude that with such little info. good luck!

Check the gap in the carb neck it should be around 2mm.

Check hsn needle,is it to lean?Then it can cut the engine out on speed runs.

How are the temps?

Are you on breakin?

Do you run in cold temps?

Do you preheat the engine before starting up?

You can have a airleak on the engine,..........

Maybe put up some pics off the needle settings.

Give more info please!!

yeh sorry i will give more details next time, however i have fixed the problem, the mixture was too lean, thanks for your replies

well i hate to tell you this....

but there really is no helping you. you need to learn to do it your self. all we can tell you is bascially the same things your book would tell you... settings that work for one person wont work for another person... reasons why is every engine is different for the biggest one!! another is weather climate, altitude. everything affects these engines.... a couple examples from my personal experience

my 4tec's stock settings are HS-4 LS-1 3/4 I-1
but my maxx wont even start on those settings... my revo starts but barley runs... all three of these cars have the exact same engine. that right there tells you every engine is different.

now for the weather.... my nearest hobby shop is 90 miles away from me, in a big city, im more in a little town and a lower elevation... when the hobby shop tunes my truck it runs great... down there, when i come back home it wont run i have to retune it... just 90 miles make a huge difference.

only advice i can really give you is take it to your local hobby shop, ask them to help you, and soak up all the info you can, and learn to tune by ear, smoke, and temp. it will take you a lot of practice, prob took me a good year atleats to learn to tune my truck really well.

Dang SSmoked!! Nothing like lending a hand... I'm new to this forum and you make a very bad first impression... :flaming: He said he was new. If you do not have the patience to help someone new then don't even make any comments...

Look Bigaza... Answer these questions first... I am going to try to download you manual and walk you through some basic stuff. This is a forum, so be patient!!! Always be patient!!! and ignore people who do not have patience to help... If you need help you can e-mail and we can go that way...

Have you done a proper break-in?
What is your current average outside temp?
Do you know your elevation? If not Google it...
Have you adjusted any needles on the carb?
