engine wont stay running without the glow starter

[apple_fanta]

my engine when itook it out last nite started up fine however it doesnt stay running when i remove the starter im guessing its the plug however cud it b a oring thing incarb if its broke etc?

Try checking your idle screw mate-it maybe out too much causing the engine to die. Try looking in your manual for the Idle screw and maybe turn in in a quarter of a turn and try. It sounds to me like the idle is too low but cant tell unless were there.. try that and come back to us. And maybe put needle settings back to factory aswell and tune from there..

im gunna try with a new glow plug tonite with my mate and if that doesnt work ill use your reccomendation and let you know you on most tonite if not tomorrow?

[MALLET]

If it doesn't start tonight, while holding open the throttle up fully, turn your bottom end screw in fully and then turn it out 5 1/2 turns out then turn the top end screw in and then turn it out 2 3/4 turns and then you should be in the right ball park on needle settings.

[apple_fanta]

Nothing is working guys I've set the needles out 5 and a half turns on bottom end and 2 and 3/4 on top end. I've changes glow plug and even let it run for a while with the ignitor on to warm up but still when I come to remove the glow starter it cuts out right away could it be fuel, fuel lines anything like that? Every possibility please mention

[dave g]

i would hazard a guess your too rich on the lsn

while the engine is running with glow starter on,nip the fuel line between finger and thumb to stop fuel flow..the engine revs should rise after a few seconds..if it rises a lot then you could be too rich on lsn,if it rises only a small amount your about right on the lsn.

[apple_fanta]

I'll see how that goes today. Fingers crossed. But even if the LSN is too rich should it still only work when the ignitor is on? Too rich mean it's extinguishing the plug right?

[dave g]

correct

if the lsn is too rich then the glow plug wont be able to stay warm enough to ignite the fuel,the glow supply keeps the plug hot.

what engine is it and what plug and fuel are you using?

[apple_fanta]

The car etc is hobao hyper 7 tq sport RTR the engine itself is a Mach 28.
It's a 20 % fuel mix I used to b on 16 %
as for the plug it's the standard one that came with it so if I'm honest I couldn't tell you coz I don't know :/ maybe the fuel and glow plug doesn't go?

[dave g]

is it a new plug you have put in?

[apple_fanta]

No it's just the same one in as from when I got the package.

[dave g]

then you need to try a new plug..

[apple_fanta]

That's just it though. I've tried another plug and the same happens.
The only thing I haven't done is the LSN so fingers crossed if not the LSN what else cud it be?

[dave g]

you tried another NEW or 2nd hand plug ?

try it and see how it goes.

[apple_fanta]

Well me and my mate were supposed to go to a race day today and ended up not going because we was not ready.
I tried his glow plug in my engine. But also it's his fuel that I used also does this still matter?

[dave g]

again..was it a NEW plug you tried?

if you change fuel then you would normally have to retune the engine a little,however since your at factory settings it will need tuning anyways.

ive never seen a hyper engine that would start and run at factory settings,they were always set way too rich.

[apple_fanta]

It's a second hand one. But as of now it's been replaced with the old one that I used before. What's your recommended settings in each needle?
I'm very new you see had the car about 2 months

[dave g]

you need to try a NEW plug.

you can set back to factory settings then lean both needles half a turn and see if it starts and runs ok...but new plug first..you see what im saying dont you??

NEW PLUG

[apple_fanta]

Yeah I get you haha get a new plug. A hotter one I'm guessing yeah?

[DCM]

I would say, start with the kit style glow plug, if you are having issue's with starting, then going back to basics...
