Optimal operating tempture?

[sharkattack99]

is all the tunning guides they say not to start tunning till your engine has warmed up to operating temps, but i doesn't say what that temp is, what is the temp? thanks

forgot to ask is there away to know for sure your idle gap is .5mm to 1mm?

I use a drill bit and put it in perpendicular (standing up along the carb wall) to the card slide. Remember to remove the venturii.

never thought about that use a 1mm drill bit thanks. do you know the optimal temp before starting to tune?

Honestly I forget about temps with the envoriment being cold. I just cover the head with a sock or aluminum foil. The only time my temp reached 200F is my first 220 cc tank, after that my temps temps never got past the 170 F range. I just put a tune that still puts out a good smoke trail throughout the RPM widthband. Explanation of how I do it is, if the motor was at performance tuned, back out the HSN 3/4 - 1/2 counterclock wise. I would set the idle gap just enough to keep your motor running. If we are talking about the Picco, after my performance tune was complete, my idle gap was 7mm at the end.

I for got to add that I left my LSN at factory until i got about the 3/4 gallon. After my 1/2 of a gallon, I turned the HSN 1/12 every tank there after

.5mm drill bit

remove the venturii

Push the slide to close position

Center drill bit to middle of the slide and have the drill bit perpendicular to the carb wall. Adjust as neccessary.

Ok experts charm in if there is something wrong.

IMO i would run it around 230F . In the manual it says to keep it under 250 for me, but since you got a different motor, I'm not too sure if it could handle running at bigger temps

thank you for taking the time to do that picture demo for me most appreciated thanks i will do that just to make sure i have the right gap.

yeah thats what the manual for my picco says to no higher than 250 had it at 260 once but not for long.

anybody know where i can get a .5mm drill bit or a 1mm drill bit? having trouble finding one.

also when i have noticed that when my engine is at 250f-260f i notice what appears to be smoke or steam (i can't tell but thats what it looks like) coming from the glow plug area my glow plug is nice and snug so its not leaking or anything is that normal?
