Quick tip: you can also use small sections of music wire (or aircraft style safety wire) in the appropriate diameter to measure the gap. A fairly common steel wire size: .020” = 0.5 mm You can usually find this in the model airplane (or train) section of your LHS.

so these little carbs don't have a dedicated (separate) idle circuit like a 2 stroke outboard or a 2 stroke jet ski motor i'm assuming since they are so tiny. interesting! any idea what the idle air gap should be for a dynamite .21 motor? the manual just says the idle air screw should be just in from flush on the needle body. why do you need to measure it if you can just tune it ... or will it make it too difficult to adjust when running?

I have been trying to get hang of this. The manual for my Losi 8ight Buggy states that the idle gap is 1/16" to 3/16" (1.57mm to 4.78mm). That seems huge compared the 0.5mm to 0.7mm you mention lol. If the idle gap is also set too large, will that cause the car to start rolling on its own? Thanks again for these helpful videos 😎👍

It’s the dynamite .28 engine and can you have a smaller idle gap than what the manual says to run.

Do you know what the idle gap should be on a ke15sp koyosho engine? I just got this nitro and am new to this. I watched your video and tried to fine tune after the break in. After getting it close. Engine stalled. Wouldn’t start. I thought my tune was off , soooooo I messed with all the settings because it wouldn’t run. Ugh it was a unexpected bad glow plug. So now I’m nowhere near where I should be. There are no factory settings that I can find to get me close.
