So me and my friend decided to drive trucks, so i bring all my stuff to his house. Everything was ok but she WOULD not start. I had a charged roto batt, the igniter was ok , glow plug was ok also. fresh batts on radio and truck. so the first thing i do is put the glow plug in, then nitro, then turned on radio and reciever , primed her by holding the exhaust pipe , and put the igniter and then tried to turn the motor over with roto, nothing worked i have her gas, almost had her but couldnt. I dont know if it was just the weather(cold)? what should i do , i feel like i have to adjust the throttle like on the radio, how should i do this, any help would be appriciated. Thanks.

If it's been a long time since you ran her... Chances are you're too rich for the cold air. You may have to open up the idle some too.

take the filter off and look into the carb make sure it's open the proper amount, if it's cold try to pre-heat the engine, also make sure that the cooling head is on tight, mine was looe and i couldn't start it for my life

how much is the proper amount maybe 2mm?

There should be a 1mm opening at idle.

If not, reset back to factory settings. It should start then, but you will need to retune.

cold weather actually requires a more rich setting to make the truck run properly. For difficult starts, I will adjust throttle trim so its getting more air and fuel. Check your plug, make sure its not shot. Its possible to over prime and blow out the filiment on a new plug if your engine has good compression especially with a roto starter. They can crank through just about anything!
