Fuel Distribution?

We keep having a problem burning # 2 piston, it always has at least a 20 bigger nozzle than the rest, any ideas? 526 KB Hi Helix with Dart heads and intake.

 

What do you have in the hat nozzles?

What temp do you have on #2 exhaust at idle, at Stage?

Your fuel pressure might be low and you can help number 2 by squeezing down your fat holes.

 

We are running a .042 area with 65% through the hat. Idle temp is very close to the rest.

 

With the hi-helix blowers (on alcohol), we always had to run double nozzles in #1, #2, and usually even #3 ports. This was to avoid running such big port nozzles that we couldn't get good atomization. We never put anything bigger than a .065 in a port line.
Good luck,
Marty

 

Roots blowers blow most of the boost in the front holes,we have run double nozzles like Marty says, you could try less COMP, IN THEM TOO,OR OTHER IF YOU KNOW HOW!!

 

I checked the computer and the temp in #2 really took off about 1 second into the run, Thanks for your input.
