HI THERE, AM PRETTY NEW TO NITRO RACING...HAVEHAD MY SACKER FOR ABOUT 3 MONTHS AND RUN A NOVASOSSI P5T ENGINE...HAVE HAD SORT OF AN ON GOING PROBLEM WITH IT CONSTANTLY STOOLING.....HAVE MESSED ABOUT WITH ALL THE LOW SPEEED, ILDE SCREWS ETC AND HAD PLP SET IT UP FOR ME, BUT STILL THE PROBLEM PERSISTS....MY CURRENT SITUATION IS THAT ITS GOING THROUGH GLOW PLUGS LIKE ANYTHING, IE TO LEAN, BUT ITS SPITTING OUT FUEL...HIGHTEMP SEALANT HAS BEEN APPLIED TO ALL AIRLEAK POSSIBLE AREAS ON ENGINE...PLS HELP.....CHEERS MITCH
NAH, GOT NO FACTORY SETTINGS WITH THE EGNGINE THAT I KNOW ABOUT, ALL I COULD THINK IS TO ADJUST ALL THE SCREWS BACK TO FLUSH POSITION AND START FROM THERE AGAIN...SO IT SOUNDS TO RICH? YOU THINK?
You should be able to find some sort of factory setting on the net. If
its spitting fuel out of the pipe, stalling and blowing glowplugs then
I'd say its running too rich and the idle is too low.
Take the airfilter off and set the idle so its open about 1-1.5mm...
that'll be a good starting point. Not sure on low speed but I reckon
you cant really go wrong with setting the high speed needle to 4-5
turns from fully screwed in. If it stalls when you go to take off from
idle and its spitting out fuel then the low speed is too rich...
gradually lean it off at 1/4 turns at a time.
Give it a try anyway.... personally I'd be going to the Novarossi site and sending them an email.
dont go down it fuel its not good generaly set the low end mixture to flush with the block then the top end to i would say three full turns out and work your way into two and three quarters out and try that and get some decent fuel get it up to 20 and make the motor work hard
CHEERS GUYS, WILL GET ME A BATCH OF PLUGS AND FUEL AND GO OUT ON WEEKEND AND TRY AGAIN...THOUGHT THAT IF IT WAS RUNNING TO RICH THEN MY MOTOR WOULD NOT BE GETTING HOT ENOUGH TO BURNT OUT THE PLUGS AFTER 5 MINS...ANYWAY,HAVE TRIED THE NOVAROSSI SITE AND CANT FIND ANYFACTORY RESETTING INFO..SO WILLPRINT OUT THESE SUGGESTIONS AND TAKE THEM WITH ME, PLUS ASK THE LOCAL HOBBY SHOP.....CHEERS ONCE AGAIN DUDES..MITCH

Yo dude, yeah i got me 2 x turbo plugs as i have a novarossi p5t turbo engine...and run on already made 25% nitro..which i have bern told is correct..
my plugs a getting a bit black on the coil, and spitting fuel, so to rich is a good start, but i have had loads of plp look and fiddle with it,so i need to start from new settings again..so have printed out you first post Oblivion and will test tomorow...would of loved to have a had a temp meter whilst tunning on sat but my main problem at the mo is to stop it stalling a and blowing plugs in 5 mins flat...cheers guys once again..
O.K folkes, thinks me have sorted it today.........wound in and out 4 .5 turns on the high sigh side......leaned out the low side by 3 massive hole turns of what it was on and ran it for 10mins with same type of turbo plug....
hey presto, no stalling on idle or low speed....ie running far to rich on low speed before me thinks....gave it a FLOGGING and my engine temp max was 130 C........It seemed to have alot of smoke on low and not much on top end without missing..so to me seems perfect...all have to do now is probably adjust low speed slightly to get it a bit more pucnhy....anyway loads better that before see original post, cheers for your engine post oblivion..................
yeah mate....i know i`m too late but the rossi motor should run less oil content fuel than most other 21 motors........i thought the fuel sounded like it was the problem...had a mate give me an 8 port to tune and it was the fuel(he had the fuel in his shed for 3 months)....i used some of my fuel and it was good.....i tune my motor from new and just change the main needle only slightly in its life time....just more concerned in racin than trying to adjust everything.......CHOW AMIGO
