ur waay to rich on the main jet. if theres no port work try 280 and go from there.

i have had 290s in and it didnt help any and when it was running before i had 330s in and it ran great with a stock bore,

[wideopenracing]

u need to drop your main there is no way your that high in elevation to need such a big jet..... hell even try 270 first with clip in stock position....

[rkpolaris]

My elevation is 1000ft above sea level

[wideopenracing]

well hell im 1330 above sea level and i run a 300 main w/ aftermarket needles on second clip down, stock pilots, all my mods are in the sig man u need to down jet

[rkpolaris]

would running too rich cause one piston to not fire regularly at idle?

[2000BansheeBoy]

dude... I'm runnin 370s with porting and all the mods in my sig and it's runnin a lil bit rich, but if your 200ft above me with 330s, i wouldnt think that's right.
But what do your plugs look like!?!?!

[bshee]

280's and sync your carbs so that they open and close at the same time/position. spark plug should be dark chocolatly brown. NOT BLACK AND WET. runnign your motor rich on jettin takes away from performance, the most amount of fuel does not translate to the most power. leaner motors produce more power. And run your fuel mixture at about 32:1 some people have different preferences though

I will try jetting it lower and see what happens I haven't been able to run it to even see what the plugs look like
