Hey Guys, I have a problem with my hpi 12r ss engine starting. At first i thought it was my glow plug, or maybe even the flywheel being loose but that wasnt it. The last time i drove it, i had glued one of the front A arms together and wanted to see if it would hold until the new one came it. It didnt and after about a lap around the parking lot it broke. Now when i tried to shut off the engine by putting my finger over the air filter it wouldnt stop. So i stopped it with the flywheel which i dont usually do ( Thats why i thought it could be loose.) I got it stopped put it away for about and the new A arm came in. I went out today and tried to get it to start but nothing. Its about 20 degrees colder today but i wouldnt thing that would make a difference. *shrug* dunno what to do Any ideas?

Thanks

try priming it.

I have a built in primer on the tank. Wasnt flooded or anything

Check you glow batteries, mixtures, and fuel lines. Make shure there's nothing in your tuned pipe.

Dead fuel? Dead glow plug? Dead or weak battery in igniter?

Check em all and report back.

The fuel was fine a week ago, The glow plug is fine, the ingniter i have plugged in right now. If The ingiter is weak but still lights up the glow plug could that still be the problem?

did you cover the air filter? or remove the air cleaner ass and cover the carb?
if you covered the carb and if didn't shut down then you must have an air leak someware.
If you covered the air filter that is a good way to force dirt to get sucked into the engine.
Nothing wrong with stopping it with the flywheel.
does the glow plug have the washer on it?
gesh hope you got it running by now.

How's your compression looking?

The air filter isn't exactly an ideal way to stop the engine

oh, it's not? i usually stop mine like that, how should i do it then? flywheel?

nope didnt push any dirt into the carb just would put my finger over the airfilter. still havent gotten it running my inginter is chargin and i hope thats it. Aterlatus The compression is great. I've only ran a gallon thru it since christmas (Broken wrist)

fiv4fghtn: The recommended ways are to let it run out of fuel, pinch the fuel line (as near to the carb as you can) or cover the exhaust outlet.

Basically, the safest way is to let it run out of fuel, but this isn't always appropriate. Pinching the line will make your motor run lean for a few seconds, and you'll most likely have to give it a quick prime before you start it again. Covering the exhaust can flood the engine but is the quickest way to stop it (save for the flywheel method).

Personally, I stick to pinching the fuel line. A few lean seconds isn't gonna cause the engine any harm and I'd rather have to re-prime than undo a glowplug to sort out a flooded block, especially with these rotostarts ripping the one-ways to pieces!
