    Jato 3.3 break in?

    I was just trying to break in my jato and I couldn't get it to hold an idle.
    The truck would start, and if I held the EZ-Start button it would work but once I let go it would shut off.
    The batt isn't fully charged and it's barely charged. Could this be the problem? It starts but just doesn't idle unless the EZ-Start is going on it.

    you may have to warm up your head with a hair drier. if you can give it a bit of throttle and keep it going then go through the break in process, 3.3's can be pains

    When I give it throttle I eventually have to give full throttle then she shuts out.
    Think it's the battery problem?
    And how do I do the hair dryer thing?

    whats the temp there? no, the battery does not have to be fully charged but has to have enught to turn the motor over. check your idle gap as well 1mm is what it should be

    Just give enought trottle to get going but not to much cuz hes very rich out of the box.
    If it will not work then lean it a little bit.

    check the glow plug, you should not give a full throttle during break in. the engine was set on rich from factory.

    Yes
    BUt im sure leaning out is not nesassary.
    I got a jato since 2 days and starting it the first time is quite hard.
    Cuz its rich and ur engine is cold.
    U just have to give that exact amount of throttle to get going.

    I checked the gap and it seems normal.
    I tried enrichening it, and it worked some but not enough.
    I did about a 1/2 turn.
    The glow plug is brand new!
    and it does start just doesn't idle, so it's most likely not the glow plug.

    well the motor is so fresh that the piston in the sleve is a bit tight, also its cold and never run before. that will help out because the temp will be hotter. also if you richened it by a 1/2 turn than it is going to be even harder to start, you are going to need to lean it through out the break in. also 1/2 a turn is way too much to lean it out being fresh

    I set it back to factory.
    Now.
    When I start it, I just put the blow dryer on the cooling head of the truck?
    Down in the glowplug or what?
    Also should I take the plug out?
    Thank you very much!!!

    Thank you very much!
    IT WORKED!!!!
    I still have to hit the gas a little from the start but I think that has to do with the engine being new. I broke in my first tank! I accidently let it run out of gas on it's own, will this affect it?
    YAY!

    stalling has a good chance of happening when breaking it in and running it fully out of nitro at first is not great but you will be ok. i ran my first 3.3 out of nitro when breaking it in on every break in tank cuz i didnt fully read directions but 2 gallons later it still runs like a champ, but you may burn up a glow plug (but you should always have a few extra on hand)

    I successfully did the break in.
    She runs like a champ.
    The idle is still a little off, but it is a matter of leaning it out I think.
    I just took it in to clean the air filter and put on some after run oil. Shes all lubed up right now. I might take her out later again to show off.
    She ran great, thank you very much for all of you help.
