I don't know why, but my tempurature is rising non stop with the McCoy MC9 and with the MC8 the temperature is around 250 F (5 - 5.5 turns out!!). And the other trouble I have is when I put 1/4 throttle, it runs fine but when i go above that it will slow down, sound different and eventually shut off! If the problem is the LSN tuning.. please tell me what people mean by starting at flush? I seems like i can keep on turning it.
Btw... when it seems that I have the correct tuning, the tempurature goes over 250 and sometimes 300 idling + running!!
I am using Byron's 25% fuel and an Ofna Hyper 7 8port with pullstart.

Flush means that the LSN is flush with the outside of the body of your carb. So unscrew it till it seems flush to the end of your carb.

I forgot to mention that I'm in Thailand so it should be hotter than the states[>:]

Did you get what I was saying about Flush?

Pretend the two top and bottom letters are your throttle body and the middle is you LSN

thanks, I'll try it 2morrow... How bout my problem with tempurature? do I have to compromise with the climate here for like 6 turns out on the HSN?! or do I need some kind of glow plug? or is it the 25% fuel making it heat up so much?

Your temps are normal. The temp is always higher when idling (there’s no air moving through the heat sink).

MiCkLe207 the sound that you here when you idle is most likly the engine loading up from being too rich. How long does it take before the sound changes? I have my idle to about 8 seconds before it loads up. If your loading up around 3 seconds or so that is why the engine dies after you punch it from idle.

I don't think mine loads up, but it idles for a long time!
btw, after 2-3 tanks i noticed that i could even pour out some oil in the exaust pipe!!
