LSN is for idle to half throttle. HSN if for WOT.
Is it bogging from a dead stop to WOT?

Hello

Hi screw the high speed mixture screw right up clock wise be carefull not to tighten to much other wise it will bend the needle. Now re-tune the car to what it says in the instructions it will be around 2 and 1/2 turnes out.


If that still doesn't work I would try a new glow plug is the one in it very old?

have you changed your fuel nitro percentage latley.(if you have that could be why it has to be re-tuned!).


have you changed glow plug brands?

hope this help.

The HSN is for tuning your engine either leaner or richer if it's bogging down it's to rich.In that case it would be blowing lots blue smoke try making it bit leaner each time trying it till it no longer bogs down it is alway better have it richer then lean your engine will last longer.Other wise if that doesn't fix the problem then try new glow plug.


Later Matt
