The car starts and then it stops.

Why does my car start and then stop? lol this is the shortest message I've ever posted. Also how can I fix the car?

Is it tuned wrong or not getting fuel to the engine?

First what buggy do you have? then what type of engine are you running? Next what type of fuel? How old is the fuel? I have had a bad batch of fuel I was holding onto and it caused my car to run like shiot!!!

Let me know what you think!

I have a lightning rr RTr I'm running a .21 size engine it's a hotbodies. I have blue thunder or blue lightning fuel and it's about 9 months old and I just opened it last week.

HIT THE BRAKES!! Your fuel is 9MONTHS OLD! Have you opened it before? Where did you store it? More then likely it is your fuel giving you hell. Now you have to expell all that crap out of your fuel lines and then your engine and tank. GET NEW FUEL!!!

Oh yeah is the engine new? If you aren't sure I would return everything to factory and re tune from there.

what?>? I just opened it last week I stored it in my garage.

no the engine is about a year old now.

 

[jon2]

still can be messin you up. I would also check your plug asit may be fouled now.

 

[6_dman_6]

Is my engine ok? Do I just need to get everything out of it and through away the gas?

 

[jon2]

your engine is probably fine. I would just restore your needles back to factory , check you r plug and expel all that fuel out of your lines and engine.

I would say so. Dumb question. Have you tried to turn the idle speed adjustment up? Or mess with the L/HSN's at all? If it is dying with in a minute at idle you can try to lean the LSN in1/16 to1/8 incraments. Unless this raises the temp above desirable temps. The richen the LSN back to where it was and raise the idle screw. If it idles for over a minute within acceptable temps try some high speed passes adjusting the HSN to reach optimal power within acceptable temp ranges. Repeat untill happy with performance, and temps from start to idle to low speeds, and high speeds. Normally takes me about a tank +/-, and 3 or 5 starts if there is major adjustment needed. If none of this helps you may want to check things like the temp range of your glow plug, and possible leaks in the fuel system from length of pressure line, cracked line or tank, to bad seal of carb to engine , and leak (bad bearing, or physical crack) in crank case. Good luck, and try all of this with some new gas incase I'm a crackpot. LOL!!

Your fuel shouldnt go bad in 9 months. it takes years ti go bad.

Sorry NO. Your fuel can go bad by leaving it in a very humid area. If you read the starge directions it says to store in a cool dry area.

Yeah, if you just opened it and it was sealed and stored out of the sun the fuel should be fine. I would try playing with the tuning like Hypedonrc said.

I agree! The sun or heat can ruin fuel and wreak havoc when tuning or even just starting!
