That can be a few things, these are some reasons and solutions (someone else correct if im wrong)

Damaged glowplug (buy new one)

Engine too cold (when starting car, leave igniter on, lift your car off the ground with one hand and give it WOT for 3-4 seconds. You can also just drive around for 30 seconds or so with the igniter on)

Idle too low (adjust idle screw)

LSN/HSN too rich (adjust correctly)

Hope that helps. My car gets that in winter, so i leave the igniter on for a few seconds and give the car WOT, the S 25 doesnt like the cold, my other cars dont even stall in the cold.

i always leave the igniter on for a few seconds so i think it could be the tuning

kurtf5

Long enough for the car to really get hot?
If so, then yes its either the idle or the LSN is too rich.

First and easiest, Put in a new glow plug.
That's the most likely problem.
In addation to the things kurt listed It could be a broken spring in the clutch bell.

DaveG55

Was the engine running fine then this problem started or are you in the middle of break in or tuning or??

I had the same problem with my F4.1. Turns out the underhead's (head button's) threads were stripped. The glow plug would not fit in properly, and this caused low compression, which also made the engine very hard to start.

kurtf5

These engines are also very tight in the first few months or running. It might help if you loosen off your glow plug a bit to give it less compression.

i already did that and the engine started to act wierd when winter came do you think i should retune it?

kurtf5

Well it could still be that the engine is still too cold, Savages hate cold, they stallall the time. It could be too rich as well, but i think the engine is too cold.

DaveG55

Like I said above, put in a new glow plug. It's cheap, easy and eliminates one possable cause. If that does not fix the problem then it's probably a tuning issue.

OK i started the engine again but this time i made sure that it was hot (can make eggs on it) and same thing happens it shuts off when i remove the igniter. should i take it to the lhs?
edit:i removed the glow plug and pluged in the igniter it seems to work fine

kurtf5

get new glowplug.

DaveG55

It's not unusual for a plug to glow on the ignitor and still be to weak to maintain the engine running. Try a new plug. I keep several spares on hand and swap them out whenever I have a similar issue. It fixes the problem a very large percentage of the time.

My Feedback: (1)

Heat your glow plug on your igniter then blow on it. The element should be RED HOT if it doesnt glow red hot OR fades when its blown on then your glow plug is shot.

kurtf5

All that determines is what temp of glowplug it is and how charged up your igniter is. It doesnt mean its "shot" if it fades. All my glowplugs fade to some extent if blown on, and i bought them new and they work perfectly, so your theory is complete nonsense tbh.

BaSh_2_tHa_mAxX

My Feedback: (1)

Its not really, a brand new glow plug will glow HOTTER and BRIGHTER when blown on. If your glowplug cant take you blowing on it, then think of nitro running over it. The fuel that these glow engines use is ALOT colder than mine or your breath.

i changed the plug the car works fine thanks guys

DaveG55

Glad to hear it.
I always keep a few glow plugs on hand as spares. Some last for a long time and some don't. I've had some only last 1 tank and some last over a gallon.
