Nikki Jets
Anybody know where you can buy larger main jets for a Nikki carb? I'm hoping to find something like 180-190 jets for the secondaries.

Mazdatrix.
A word to the wise though: 180-190 for sec main jets might be a little too much for a 12A (is it streetported?). Don't ask me how I know.

The engine is a stock 12a with full RB exhaust and some other stuff you can see in my sig. Just looking for a little more go power. Thanks again for the info.

at most i would only go up to a 170. get a better pump and regulator. that's usually the first thing you do to get more fuel up top. your fuel pump is probably getting tired and just isnt doing the job.

Fuel filter is good, and the carb is finally all cleaned out. It just seems like it used to go to the redline so fast that you'd hit the damned buzzer before you had a chance to shift. Now it seems like it takes a lot longer to actually get near the redline.
But like I said, no chugging or sputtering. Power is smooth all the way to the redline, but there just doesn't seem to be a whole lot of it. Got to find more ponies!

My $0.02. Sterling can probably give you better advice, and he would probably tell you "leave yer secondary jets alone!".

Fuel pressure eh?
It has been my understanding that as long as there was adequate fuel in the bowls, then the carb has what it needs. If the fuel was draining from the bowls at a higher rate than it could be replaced, then I should be able to feel it sputtering or bogging or something along those lines.
Either I'm missing something here, or fuel pressure is not the issue. Please correct me if I am wrong... Thanks.

Both volume AND pressure are important. You cant see whats happening in the bowls while your driving. A simple clogged filter can cause hi rpm power loss due to fuel starvation. And it wont necessarily manifest itself in the way you described. It would depend on the severity of the starvation.
Upgrade the pump and get an FPR and a gauge.
Oh and 180-190's are too big for that carby.
