Need more info, what have you already checked. Did you verify that you have enough throttle cable travel?

Dave
I will have to check several items and that its one of them
I am running a very old e6k , tps reference,
304 cams, 12,5 Cr, afr last run was 11,7
I sent the injectors to clean( i bought thise ones in ebay yellow color , supposedly 290 cc, plead correct me)
Soo yes , I will have a check on that

11.7 AFR is too rich and that amount of extra fuel will make a difference to the power.
Aim for something around 12.8 at full throttle.

As mentioned the A/F ratio, but my guess is cam timing. I would verify BOTH cams. With 304* cams you should be just be coming up on the power band at 6,500 RPM. Either borrow or invest in a dial indicator and a degree wheel. [cam(s) probably advanced] After adjusting the cams, re-set timing. Davew7

Yes, I will change the injectors, are too big
