Nitro Engine dies when take glow plug off

[Layloo9136]

Hi all

Its been a long time since I ran an RC car and the last ones I bought were off a mate so already run in.

Running in my Losi 8ight, took me best part of 8 hours to get the thing going and ran 1 tank through then it died when I topped it up.

Now I can get it going again but it dies as soon as I take the glow plug off, whether in 30 seconds or three minutes?

Why please?

Thank you

It's a brand new engine?
Do you have set the carburator?
What engine is it?

Normally when it dies when you take the glow off its because it's get to much fuel / stationary is set to low...

Try to set it a little bit leaner or set the stationary a little bit higher ...

Lean off a little and turn tick over up.

You need a new glow plug.

It could be many things..

Blown Plug
Idle to low
Needs leaning up a touch.

I would check, and make sure all the needles are to factory settings. Then lean the Top end quarter of a full turn. And adjust the tick over as a lot of engines factory needle settings are too rich. Check your glow plug, take it out and place it in the glow ignitor. Make sure its fully charge-(Glow Starter) and that the filament is glowing bright. And use a heat gun or a RC Sure-Start to warm up the engine before starting-Makes life 100x easier.

If you still have no luck,let me know or take it to a local track or hobby shop. And get someone to have a look at it for you.

Thanks folks. I did what was reccomended. I put some black marker on a screwdriver then wound the low speed needle back in then unscrewed 4 turns as per the instructions. I then leaned it another half turn and increased the idle and that did the trick so thanks folks.

Thats 2.5 taks run thorugh it now so should be time to have a gentle go on the ground

(as per the question above, its the Losi 350 engine that comes with the 8ight)

Great stuff glad you have it sorted!

I highly recommend a RC Sure-Start

Its a great way to help aid starting your engine-specially in the winter, and will help your engine's lifespan. I have been running 1/8th for over 2 years, and it has been one of the best buys so far. And has many top driver's backing the product!!

One thing I would do is change the plug straight away,no matter what other of the abouve tricks you try,
