what I did was add the 8 mm restrictor, richen the LSN 2hr and richen the HSN 1.5 HR.
3 laps into the main it flames out. my pit guy doesn`t know how to adjust needles so I tell him to just re-start and get me back out.
3 laps later she flames again. oh I was using an rb #6 plug.
did this happen because it was to rich?
I am going to look at it today.
It sounds like you changed restrictors? what was in there before? You must do some retuning if you change restrictors.

happy motorin guys,

Houston, from what you wrote it seems that Novas like running a hot Plug, most of the plugs you suggested are hot plugs bar the NR 6 (medium). All this time I was under the assumption that NR like a warm plug at the least and on blistering hot days it was wise for me to move to a cold plug No 7. Unlike the OS Vspecs they seem to thrive on P3 in almost all conditions.

Any input would be greatly appreciated.

it sounds to like you richened it way to much what restricter was in there before the 8mm and what were the temps before you richened it?
