Do I Need To Advance Timing?


Recommended Posts

I was told that with all my mods (Toomey T-5's, v-force reeds, wisesco pistons .20 over, low-mid porting, intake porting, noss head, 20cc domes, 2 into 1 keihin 35mm carb, and k&n filter) that I need to increase the timing. Do I need to? I was also told that the carb won't work right unless I get a fuel pump and new reeds. The carb has a power jet, and thats why the guy said I would need a fuel pump and new reeds. Is there a way to shut off the power jet? This is from his email: "power jet carbs suck you will not be able to keep the bowl full unless put in a 2 psi electric fuel pump when you go full throttle back off hit it agian, blows too much fuel then leans used these back in the 70s and they have not changed still suck, they put fuel in or lean it they are very inconsistence for air fuel ratios". Is any of that true? I am totally lost here, I've had 3 different people tell me 3 different things about jetting and this guy is telling me my setup sucks and it wont work. What should I do?
