List, 

I'm trying to dial in a single Weber DCOE 40 on my 1296 Spitfire and was 
wondering what main jets and air correctors others were using successfully. I'm 
at 5300 ft. altitude here in Colorado so I can adjust for that from the numbers 
you provide. I'm hoping to get some baseline numbers from anyone with similar 
sized engines running a DCOE 40. Really can be Sprites, Sprigets, or Spitfires 
anything similar. 

Right now I'm running a 125 main jet with a 160 air corrector but when reving 
the engine it falls flat at about 3500-4000 rpm (when I assume its gone through 
the progression and is into the main circuit). The spark plugs look clean, too 
clean, with only a bit of brown chocolate color on #4 plug. I'm thinking I need 
to go richer (bigger hole) on the main jet or smaller on the air corrector. 

Before I order MORE jets and air correctors I'd love some advice and input. 

Thanks 
Bud Rolofson
