i broguht a kyosho inferno st us sports about 3 days ago and since then i have not been able to find a rich setting that works i have run in a rush evo and a savage had no problems this engine now cuts out no matter what setting its on it either get drowned by to much fuel or goes to lean and cuts out any suggestions o and by the way the fuel i got with it was something like 10 percent would that make a difference to wether its gona work or not?

qaiz

Im just guessing this, but 10% would not be good to start with, its probably burning to hot and maybe overheating.

You should go for something more like 20%.

And is the engine starting alright.?

qaiz

Oh, and welcome to the forums.

unrealfacry

well yeh the engine is brand new hasnt even bin broken in yet but i cant even do that because if the engine gets a hint of throttle its either over heating or geting smothered with fuel.

unrealfacry

and thanks for the welcome

qaiz

Im guessing it would be the fuel then, because again, im guessing you know how to tune an engine.

The lower the percentage, the hotter the engine will burn, and I know for a fact the 10% is really low.

Most of us here use about 20% - 30%.

I broke in my engine with 20% and have never had a problem till today.

Try using 20%.

unrealfacry

ok well im gona try the 10% in the savage if anything my savage should have problems with that fuel to right?

qaiz

I really wouldnt try that,

10% really to low, I think.

Most engines use 20% at a minimum.

Check your user manual and check what it says.

What percentage of nitro would be sufficent.

unrealfacry

yh iwas looking thro the manuals it didnt specify which to use but it did in the german section it said 15-25% but on the parts list it had 20-30% availible for the car.

qaiz

Yeah, thats what I thought.

10% Is too low.

Switch to 20%.

Dont run it on 10%, it could possibly damage your engine.

unrealfacry

ok i will get some 25% fuel from a friend tomorrow and try it and post my results.
so if an engine had to low fuel percentage it wouldnt run properly at all would it?

qaiz

The lower the percentage, the hotter the engine will burn, and most likely over heat and place unneccessary stress on the piston and piston sleeve.

Its best that you use anything between 20% - 30%.

20% - 25% will work fine.

Let me know how it all turns out

slayerphonics

ya 10% is a joke i saw some kida trying to run 10% and he had the same problems.. no need to run lower nitro to break in the engine use the same % you break in with just don't just 10%... 20% + 30% is what i would use in a truggy though

unrealfacry

hmm ive neva used less than 16 percent fuel in my life just that dealer who sold me the kyosho was like yeh thats fine it should run on 10 % fuel
he even tuned in i got it home it worked for 2 minutes and over heated. well il take it back and make him give me a highher percent

qaiz

Hit the dealer lol.

Hes an iDioT

10's too low.

I use 20 for bashing sometimes, otherwise im always at 30.

I wanna try using 40 or 50 tho.

Thats my new years resoloution

unrealfacry

well for the past 3 days ive bin trying to get the car to work on it ive used about a tank and a half on the car and it hasnt even bin bvroken in do u reckon i might of shortened its life?

qaiz

Well if you havent floored it or WOT'd it, it should be alright.

All engines can survive one mishandling inciden.

slayerphonics

Better think about your plug; the higher nitro % you go the colder your plug will get.. your plug could be bad take it and look at where coiled wire touches the edge of plug.. thats like the idle bar that can be burned up but the plug will still glow deep inside causing all kinds of problems

I run the coldest plugs 10's on 30% never seem to have a problem

qaiz

@ slayer,

True.

Im trying to get a hold of a main;s customer service lol, im changing my order for my Losi 8ight T Race Roller to the RTR version.

Thank God it hasnt shipped.!

unrealfacry

well happy new year guys just got back in i have checked the glow plugs even used a hotter one and still the same response so im just gona try higher fuel in the morning so what happens

mtbkym01

I broke in a GXR28 with 15% nitro. Remember that they are a pig when new and run like crap. One thing to also consider is air leaks, the GXR28 is prone to them, and they can cause havoc with your tune. Check the sticky titled "Nitro Guide and FAQ's" in the engine section. It will tell you how to deal with airleaks. Oh and BTW, a Glow engine will run on 0% nitro fuel

qaiz

@ mtbkym01

Yeah an engine will work on 0% nitro, but it will be an absoloute P.I.A.! to hold a tune or try to tune.

And reduced preformance.

mtbkym01

Well performance isnt an issue at this stage, I almost guarantee that he has airleaks, believe me I know

Tweedybird

If you want to use 30% break the motor in with 20% first then switch over to 30% and idle a few tanks in for the new fuel to settle into the motor before you get on it. Then you should be set. Also buy a few extra plugs, I always go through a few breaking in a new motor.

Let us know how you make out.

well today i got 25% fuel put everything to default and put it in it started instantly no problems, after i had my second tank inside the car, i gave it some throttle and the thing flew!! its clear that 10% fuel does not work inside the GXR.28 just so u know what fuel they both were : the 10% was model technics QWIKFIRE 10 glow fuel and the 25% today was tornado 25%. only problem is i couldnt get it to run really rich it was sitting on a perfect tune in so i just left it. so for anyone geting a gxr.28 do not use 10% LOL
