Ran my savage after a week had to wait for a new slipper,and i put both my needles bach to flush to tune it,and after 30 seconds it was realy hot,leaned it up abit and ran it for 5 mintues now it was getting very very hot with smoke coming out of the engine,why is it running so hot??

Well making it leaner will cause it to run hotter, try richening it abit, heres a quick tip, put a dab of spit on the engine head, if it fizzles away violently its way to hot, if you have temp gauge use that even better lol, report back

If I were you, I would put the needles back into their seats and then turn them out to 2.5 to 3 turns out (I use this as a rule of thumb), then run it at idel for a few minutes and do the spit test as detailed above by dgreat001.

If you watch the hpi videos it tells you that,but if you read the engine manual,it tells to set the needles flush,confused aint the word.

I follow the engine manual settings at its been fine.

base setting change depending on fuel, 25% - HSN 4turns out, LSN 4 turns out

20% - each needle at 3 turns out

I had the same problem with my savvy (when I had it) I could never get it to run this time of year,it was always over heating which resulted in my flooding it and snapping pull starts all the time.

In the winter no probs at all - roll on!

If the engine is too hot you richen the settings.  Why would you lean-it would make it hotter?

Hot weather requires a leaner mixture setting; cold weather requires a richer setting. Most people assume the opposite because they treat the mixture needle like a thermostat. It is wrong to assume that colder weather requires a leaner setting to keep heat in the engine and vice versa.

Cold air is denser than hot air. The denser, colder air packs more oxygen into the engine, so going from hot weather to cold needs a commensurate increase of fuel to balance ratio of fuel-burning oxygen and the fuel itself. The opposite is true in hotter weather. Going from cold to hot weather requires a leaner mixture setting,

:rolleyes:

To achieve your optimum tune, the mixture setting will affect engine temperature in the usual way; richaning the HSN will bring the running temperature down, etc

But mad hatter is correct in the fine adjustments required for the ambient temperature and other environmental factors that the engine is operating in.

If my engine is hot, I richen the settings and it runs cooler-worked for me.  I take your point though.

yeh its sounds backwards buts tru,however theres a fine line between the lean summer setting, the only car I have managed to get it right on is the menace, savage did'nt want to know rich or lean in the summer months.
