PEOPLE STOP LOOKIN AT MY THREAD AND HELP ME MY CARS SLOW :banghead:

Since your a newbie let me teach you something. I have been here for nearly 2 years. It takes people awhile to answer a question, half the time they arent going to respond in just 3 hours. So dont get all pissy and make a big post telling us to help you.

And if you're going to be a jackass nobody will help you. Just give it some time.

yeah, i think i may have the same problem, or close to it with my tmaxx, and i think it may be either because i left some fuel in the tank for more than 6 months, or something just broke, im not really sure

You need to adjust your fuel air mixture. If your vehicle has a high and a low setting adjust the high setting. It should be a knob near where the fuel line atacheds to the carb.

Oh snap. You got served. Just kidding yo. Gas cars aren't my thing.

Does the engine seem to bog down before it dies? (sound clogged up and seems to slow down) If so...it sounds like you are running it too rich...too much fuel is getting into the carb and flooding the engine. First warm up the engine. Then adjust the high speed needle 1/8 of a turn at a time clockwise. Run it around a bit with each adjustment. Don't lean it out too much, make sure some blue-ish smoke is comming out of the exhaust and check the temprature (approx 250 degrees F is a good temp to shoot for). If after this, it still seems to bog down (if it does, it should be doing it after you really peg the throttle but not if you slowly accellerate), start adjusting the low end needle...lean it out. Just adjust it a little at a time though...a little goes a long way on this one. Also pay attention to the temp on this one...you can easily get it too hot leaning the mixture with this screw.

thanks Asmenoth ill give it a tryand ill check out that site

nothing is blocking the fuel lines it might be the mixture

i thought more fuel in the top end will help with full throttle

is rich anti clockwise and lean clock wise?

wat u mean bog down?
like a bout to stall

i can prevent the car from stalling if i let go of the throttle before its about to die

i wanna get the idle really low

does the low speed needle do any thing concerning top end

thanks Asmenoth ill give it a tryand ill check out that site

is rich anti clockwise and lean clock wise?

No, there's a limit to how much fuel can be burned, too much and the engine floods and dies.

And yes, rich is anti clockwise and lean is clockwise. The adjustment needles are like screws at a "t" intersection, screw going down intercepting the fuel going across. The more you tighten the screw, the less fuel can cross the intersection...leaning the mixture. And unscrewing it, richens the mix.

Yes, bogging down is about to stall.

Once the other needles are adjusted (though they should never stay the same, you will have to adjust them according to the weather, hot and dry-richen the mix, cold and dry- lean it out, etc.) adjust the idle screw. Before break in of the engine, the idle screw should have allready been adjusted. Take off the air filter and turn it clockwise (or counter clockwise as needed) to make the gap (looking into the top of the carb you will see a needle, the gap to the right of the needle) 1-2mm. The bigger the gap, the higher the idle. Don't adjust it too low, or it will stall sitting still.

No, the low speed needle doesn't do anything for top end, but it does control throttle response. If it's too rich, the engine will hesitate before taking off. Too lean, well...it will overheat the engine (bad).

Hopefully, your local hobby shop carries the books that are on R/C CarAction's web site. If not, try to get them online. Don't recall the names off hand, but they are really useful and recommended. Great tips and such.

:biggrin:

thanks for da help dude (asmenoth)

unfortunately i wont be able to run my car for a while because i melted my clutch now its stuck to the clutch bell and if i stop completely the car will stall :banghead:

i've just bought a two speed transmission lately do i need the engine to rev out before it changes gear? :dunno:

man my car has too many problems it sucks :mad:

Well, that doesn't sound too bad, just get new clutch shoes and probably retainer spring (or springs one for each shoe)...fairly cheap. You should be able to clean out the clutch bell without too much trouble.

No it doesn't have to rev out to shift. Matter of fact, you should be able to adjust the shift point on the two speed. Hopefully the instructions are understandable as not all 2 speeds are built the same. Learning how to adjust the transmission is a must for racing as you can change when it shifts for different tracks.

:biggrin:

IVE ADJUSTED IT TO SHIFT REALLY EARLY BUT JUST WON'T

my car can hit full when i take off and go on for a bout a metre then dies

i've leaned it out a bit it says on a manual for a different engine that stock mixtures are 2 1/2 to 3
and i have it on three full turns from closed

does weahter have anything to do with it?

sorry for asking too many questions but my6 friend wants to know if a force 21 (nitro) is good and will it fit on a 1/10 scale?

thanks for all your help guys

Those settings are where you start when the engine is brand new and has to be broken in. At 3 turns out...that's too rich. From that point you should start leaning the mixture out a bit.

As for the tranny, even though it is set to shift early, the engine will still have to reach a ceartain RPM and stay there for a second or two.

Force 21 huh? Never had one, but have heard pretty good things from people about it. Now, as for the 1/10 scale...car? Truck? Buggy? Depending on what it is, some companies make conversion kits to put .21 engines into 1/10 vehicles. But most 1/10 vehicles aren't designed to let a .21 just drop into it with out some modification. You can only do that with .12-.15 or even a .18 engines.

:biggrin:

ok how does 2 or 2 1/2 turn sound is that good
to me its not that good because when u take off fast it bogs down then speeds back up

my friend has got a kyosho i think its called....mkII... it a road car

That sounds fine, but work your way down, an 1/8 of a turn at a time. You may find you might night have to go that lean...or leaner. Just make sure some bluish smoke is comming out of the pipe and the temp stays between 250-290 F. The bogging down you are experiencing is from the low speed needle being too rich, lean it down a bit and that bogging should go away.

As for the Kyosho...it might be possible to wedge a .21 in there...but I am not sure if anyone makes a conversion kit to accomidate the larger engine. I've seen the guys in the R/C magazines do some crazy stuff, but most of the parts had to be custom made...like the 100mph nitro car. I think the article is still on the R/C CarAction website.

:biggrin:

thanks dude ill try what you said. i thought that the low speed needle had something to do with the bogging down

is the force 21 a road,buggy,or truck engine?

The Force 21 I believe was orginally designed for 1/8 scale buggies. But now aftermarket conversion kits are becomming quite common for the large monster trucks, T-Maxx, Terra Crusher etc. And I think they also make conversion kits for the larger road cars, HPI's RS4 Super Nitro, Kyosho's Super 10 and others (these cars, for some reason, are listed as 1/10 scale...but are actually bigger than 1/10).

:biggrin:

tanks man

hey when my petrol tank is near empty i can hit full throttle and stay there i'm confused

but i wasn;t going any where because my tyre fell off is it any different when the car is moving and the car isnt if ur reving it?

It was acting different when the tire fell off because there was no load on the engine. Put the car on a car stand and rev the engine...should have the same effect. As for the low tank thing...when the fuel gets low...the engine seems to lean out and rev up. Less fuel in the tank and more air forcing the fuel out.

:biggrin:

o ok thanks dude u have been a great help
