Engine bog down when first started

[Jabawarkie]

Hi I'm new here so go easy on me, i have a serpent 966 evo with a picco torque 21 edo modifide edition, when i start the engine recently on the starter bow its bogs down, when i hold the throttle in it jisst doesn't do anything at all and sometimes stalls, this lasts for around 30 seconds then all of a sudden springs to life, any ideas why this would be? Thanks in advance for your replys

It needs some warm up time. Don't push it till it gets ready.

I think its normal, because mine does that too, just gentally give it LITTLE throttle for about 10 - 15 seconds. or if it doesn't stall, just let it sit ther for 20 seconds, then it will run good. =)

the u can stop this by pre-heating the engine with a hair drier or heat gun before u start it.

x2 if it still does it after warming up,turn your hsn 1/8 turn at a time (clockwise)hitting throttle on tx after each turn til you get wot without any bogging,sounds like your running rich.

Yeah it's good to be running rich on a cold engine, because once it warms up it will be running less rich.

My revo will bog when started (even die when hitting throttle), until it get to 160 F or so.

Let it sit and idle until it gets nice and warm, then punch the gas!

let it warm up its not like your real car that has fuel injection. LoL

If it's boggy near or at idle once it's warmed up, use the LSN to adjust for this as the HSN has no control over the low rpm hence the name, High Speed Needle. The LSN controls the fuel flow until the carb is opened 1/4 or so, then the HSN takes over and the LSN has no effect from there to the top. From 1/4 throttle to idle the HSN has no control on fuel flow and the LSN meters how much fuel is flowing through the carb so you must adjust the LSN for that.
