but now i'm having a problem with the temperature of the motor keeps increasing to around 145 degrees celcius before i shut the motor down.
I have a very visable trail of blue smoke when accelerating and also when i pinch the fuel line at idle it will increase rpm and then die in about 3 seconds later.
i've tried adjusting the LSN but i think its already running very rich, anymore and the car starts to splutter and makes it sluggish when taking off.
The only thing i can think of is the way my temps measured, i don't have a thermometre

but i use the thermosensor on the dx2s receiver and i have no idea how accurates at those high temps, it usually reads about 4 degrees hotter than room temp.
thanks.
145 C/ 293 f is way too hot. I have 3 AXE Rossi's and I've always had to tear them down and seal them up good after break in. They always seemed to have a leak somewhere and ran high temps and erratic idles unitll sealed. I use my Mamba as a back up engine but it's as good as anything out there.
