Default Sirio .12 Turbo

I was wondering if someone could give me a good overall setting for the Sirio .12 turbo. I keep on using up plugs like no tomorrow and it doesn't run for the entire race (about 5-6 minutes). Any help would be awsome.

It might be that. Because one day the glow pug worked and then died, then the next day it worked again. I'll lean it out some.

Default retune

Maybe you can return your engine...........rich up high and low end. Start from low end.......lean it by 1/8 a time and make sure check the temp every time u lean. After very good accerelation and the temp are in the spec than set the high needler.

I found that messing around with the low end needle and finding the perfect setting is the best way to do it. If you have a centax try loosening it up.

I have it 3 1/2 turns out, but it will probably be different with a three shoe clutch, but you might as well try it anyway. Make sure you're adjusting the needle that is in the throttle slide.

Well I have my highend at 5 1/4 turns out but it's running really rich so I'd say you should put in 4 3/4 and then if you need to lean it in a little more. As for my mid needle thats the one thats 3 1/2 turns out.

Don't adjust the mid needler. Just adjust it flat with the carb body if you have adjust it.

I had the mid needle 3 turns out I will try 3.5 out and see when we were taking it out it was getting better but ran out of daylight, and if its flush with the carb body its all the way screwed in.
thanks
