    Not an issue with these like a nitro.. as long as there is some spatter and it runs well enjoy it.

    so they hard to lean out and burn?
    cause my first engine was runnig 25:1 and it barely smoke but my chainsaw(22cc) runs on 50:1 and it smokes twice what the buggy those so I think I was running to lean but it was runnnig and sounding good.
    Its troath sonuded clearer then the saw.
    I,m worried that I`m leaning out my low end to much because I`m use to the accleration form 0 to 20 of nitro.
    will it stall on me when I pull the trigger like nitro does if i lean low to much?
    what are the sign of low neddle to lean?
    thanks!

    Here is some helpful information regarding common carburetor tuning problems:

    If your engine stutters at full throttle and cannot reach full RPMs:
    The high jet is too far open. Close the jet by turning it clockwise slightly, and then ride-test. If no improvement, repeat until desired results are achieved. Once you have found a workable setting, open the jet approx 1/16 of a turn to ensure sufficient fuel/air mix.

    If your engine bogs out when transitioning from low speed:
    The high jet is too far closed. Open the jet by turning it counterclockwise until you are at least 1 1/2 turns open, and then gradually close the jet until performance is as desired. Poor engine compression, blocked exhausts, and very heavy engine loading can all also cause bogging.

    If your engine idles very fast and kills if you attempt to slow the idle:
    You may have an air leak in your intake. An easy way to check for leaks is to spray the intake manifold and area surrounding it with WD-40. If the idle changes after you spray the WD-40, there is an air leak. Common areas for leaks are between the manifold and the cylinder, and between the carb and the intake manifold. Inspect the manifold, carb gasket, and intake gasket for cracks or other signs of damage, and replace if necessary.

    If your engine idles but then slowly kills:
    Your low jet is too far open. Close the low jet by turning it clockwise until a stable idle is achieved.

    so you use low speed to get good idle and once you get good idle then you set high neddle for performance and it affect both low and high speed acc?
    alot less fancy then nitro!
    and my wing was ditry but my back chassis is not spattered with gunk.
    but it only lasted 3/4 of tank so it maybe did run long enough!
    but long enough to let the other 1/8 guys at the track that a tiger is loose!Lol!!
    i think it wont be long before I see other baja.Say when they come out!
    At least 3 are comming just because of a 3/4 tank show!

    Good writeup mradlin. I'm pretty new to tuning these gas engines but here is some additional tuning advice I have received.

    You can turn high, low, and idle pretty much independently of each other, unlike nitro.

    When race tuning, run the car at race speeds for about 10 minutes and bring it in. If the fuel primer bulb is empty, you are too lean on the high needle.
