Jato not running right! Please help before its set on fire!

[pat ws6]

note that the car wont want to idle without the igniter in it. but when the igniter is engaged it seems to drive around semi decent. where is everyone buying glow plugs?

[Mind_Reader7]

How open is the idle gap?

Turn the HSN 1/8 counter clockwise.

[koko_puff]

Make sure you are using a "hot" plug. Get an o.s. hot plug. If it runs with the igniter on it and dies when you take it off its a bad plug.

[pat ws6]

i believe my whole problem is a bad plug. which os plug would u reccommend?

[pat ws6]

which hot plug ? o.s. makes about 4 'hot' plugs

[pat ws6]

[pat ws6]

i will keep yall updated thanks again jato bros

[pat ws6]

put new plugs in and it fixed all my issues. the only thing is i cant get the car to get moving in 2nd gear. first it rips pretty good. but second seems to bog down. when i go to lean it out it dies @ WOT

[hnnguyen85]

That means that your way too lean. Richen up the hsn a 1/4 turn and retest. Keep doing this until it no longer bogs or dies out. Then richen it another 1/8 turn and you should be good to go

tell me what yall think with the AFR

[pat ws6]

FRIED 2 glow plugs in 3 hours.... how is this possible if i have been trying to lean it out?

[pat ws6]

the coils inside the glow plugs are ending up all twisted. they dont look straight any more...? what gives?

[Double G]

There was a Jato vid there? All I was watching where the turbo LS1's

If you are burning through plugs then you are too lean. You must richen the HSN by turning it counter-clockwise.

[pat ws6]

it was still rich! when the new plugs were in there it was smoking and running rich. it was dogggg slow so i leaned it out a half turn and then it died and the glow plugedit this thing is such a piece of crap. 16 bucks in glow plugs down the drain. the coil looks all bent up... the car is just slow and then when u barley lean it out it dies???????????????????

If you have it at factory and it's slow or bogging then it's too rich.

I honestly suggest you take it to a hobby shop, and ask them to tune it. Although it may cost a pretty penny, it'll at least give you a starting point.

[brett.schroder]

Did you buy the car new or used? I see that you don't know how much fuel is through it, if you bought it used the engine may be shot. Buying used I always go into it as if the engine is shot (for price) unless I know the person and the history of the truck. If you did buy used and don't know the history, there is a good chance that the engine may be toast (especially if the leak in the carb has been there a while), if the previous owner didn't do a proper break in or have a good tune the engine may be done. When they are on they're last leg, they may have compression at room temp but as they heat up the piston sleeve will lossen up causing a tuning nightmare. If it was me, I would either do the power up and get a new 3.3 along witha carb for the Losi 3.4 or just grab a Dynamite .19, trying to save a dying engine will just frustrate you and probably make you leave this hobby. Also, watch the language, I know you're probably frustrated but you have already been warned by the Mods and you won't get any help if your thread gets shutdown.

One of my friends car was doing the same thing. His high speed needle had stripped out, he only had it for 3 days

[pat ws6]

You'll just have the exact same problem if you buy a new motor.
This should help you out.

It could be a bad engine, however, if it is not, switching to OS will not automatically cure the problem.

it is pig slowwwwwwwww at factory needle settings? what could this be. plz help

I see a lot of posting about tuning the HSN,,,, Don't see anything about the LSN.... If the LSN is not set right, the HSN will never be...

Typical symptom of a lean LSN and a rich HSN = smoke trails, boggy performance AND HIGH TEMPS.....

So.... do the Pinch Test on the LSN. By pinching the fuel line 1-2" from the fuel inlet and counting in seconds, it should run for 3-4 seconds then stall.

Less than 3 seconds the LSN is too lean, richen it up 1/16th a turn counter clockwise. Start it up, do a WOT pass and re test.

More than 4 seconds, the LSN is too rich, lean it up turning the LSN 1/16th a turn clockwise, do another WOT pass and retest...

Always tune with no more than 1/2 a tank. For more details clock on this. But you HSN will never be right without tuning the LSN. THEY ARE EXTREMELY DEPENDENT ON EACH OTHER...

You should tune in a specific order as well.
First the HSn as best as you can get it from factory.
Second the LSN
Third fine tune the HSN for performance
Forth set your idle.
