Did you chase the passages and jet orifices with a fine wire to ensure that they were clear?

rampage wont run fast

had it apart everuy thing looked ok. However just ordered a carb kit and will
give it a better look after i get it new jets seats and gaskets.
Do you think it could be crank seals or is the fuel pump i bought too small?
