Os speed runch rich
#1

i have had some issues with my os speed engines.
idles great and all day,trow it onto the track and it runs great on top.
i have problem clearing small dobbles and tripples...clears big jumps with ease, as long as i have a couple of meters run up.
only issue is it gets richer on bottom when engine is run for 2-3 mins...feels like its getting richer anyway
have checked for leaks,new bearings checked for slop in setup.
hope i made myself clear?
anybody has any ideas?

Never tune a cold engine. Tune it at temp. If the bottom is too rich when warm, lean it. If it idles too high after that, back off on the idle.

okey ill have a go tomorrow.
but i do belive its lean enough on the bottom.
i always warm up my enigine before i run it, so it has like 3-4 mins getting up temps before i drive each heat. and i also preheat engine with hair drier.
the engine is warm before i trow it onto the track.

let me be even more clear 
we have heats of 5 mins, 3 mins warm up before that, prior to that i warm up engine for 3-4 mins on starter box, prior to that i use hair drier for a while to pre heat engine.
so thats total of 6-7 mins of engine running before heat starts, do you still think its not warm?
i will try to lean out engine on bottom even more se if it helps.
i have a ninja jx and it runs great all day with same warm up procedure
just concidering what to do with this, leave engines be or chuck them in the bin.
next season i will have 4 REDS engines to play with som my last season with Speed. 99% sure
