Tuning An Engine

I have also been having problems with my Novarossi that I just got. When I got full throttle on the straight then let go it does not idle down it takes like 4-5 seconds to completely idle. The gap is pretty small. Also when I come in the pits, the car has like a hanging idle. Any ideas? lean LSN or idle gap open to much?

I'd say too lean on the top, too rich on the bottom. 1h out on the top, 1h in on the bottom and lower the idle a bit.
if you richen the bottom you'll only get the idle down because it is running too rich and you lose bottom end power and so on.

I think that the LSN is ok, after the straight the engine makes a clattering noise( after releasing the throttle completely), so I assume to lean up top? Temps are around 250.

yeah get the temps back to 220. Richining it up half a turn and start over there

Ok, what temps do you run your engines?

220 - 240

So you guys recommend making it leaner on the top a richer on the button?

richer the top

[kyoshoracer]

Do most of you guys go a bit lean on the bottom and rich on the top?

richer the top

What's the highest temperature I can run my engine?

a good temp is around 230

[kyoshoracer]

Do you think anything over 230 is way to hot?

I've run some bonitos around 300. But anything over 260 is to hot. No need to be above that

[kyoshoracer]

Are the engines still good after being around 300? Is 300 degrees after a 45 min main?

yes, just a little shorter life span

Quick question, what does it mean when the mid speed needle is set to "flush".
