Hi all
I just finished the 90 pred and it seems good but need help with one thing, It has a Hetricks power up kit with the red springs and a 90 jet.
On take off there is no power the engine labors and slowly revs up,gaining speed gradually, once reved up it runs great all sorts of speed. if you keep the rpms up its a rocket, even if you come to a short stop. if you let it sit for 15 seconds or so the engine rpms come down and then the engine labors again to gain speed and rpm's
I also noticed that when driving around once up to speed, it seems to break up if you keep the rpms below a certin point, just a little more gas and it clears out and sounds smooth and sweet.
Any Ideas, is it jetting maybe ? or possibly stall speed? I am leaning away from stall speed (clutch stuff) because the engine seems labored on start up I think if it were clutch it would rev up just not take off.
