Nitro

[Jeff Smith]

any body got a base line as far as main jet size when going from straight alky to 10% nitro? I'm running a Rons and they don"t have much info for me.

Other than a little smell,
I dought you will notice the attempt to wake up your motor untill
18-22 %,..the nitro will be denser by weight and volume, but
for your 10 % I would leave the main alone unless you start upping the percentage, maybe half a flat on the valve to richen it up for idle,....run it as it is then read the plugs.
it couldnt be more than a 2 or 3 jetting fatter change with only 10%.

I run about 25 % and very little change, maybe fatten it up the low end a touch but for the most part you are running so little I don't think I would worry about it too much , Check the heat on the motor to see if it is running lean or not and thats about it,
Good Luck.

Thanks guys. When I added the nitro I fattened it up .015 and richened the barrel valve 1/2 a flat(about 1/2 lb more leakage), it picked up a 10th. Seemed just a touch lean though. Just wondering if I should dump even more fuel in it.

What did you plugs say,..lean or perfect

you could add 5% more fuel,.or put .005 back in the main
to richen it back up.

addictive aint it,.... ;D

[bud]

it all depends on how often you want to pull the motor down as to how much fuel you want to add,

the bigger the bang the bigger the
