something is getting lost in the translation here it was the secound test and tune with the car ,ran the car with an 850 i had, its laying down on the top end thats why we test and tune to figure these things out, now im putting together another 850 was just looking for input on jetting, ordered a set of 88 and 92 jets and 4.5 power valves new floats as im still running the old brass ones, in my spare parts i have 76 jets 80 jets and 84 jets and power valve plugs and old power valves was just looking for imput and then some ahole starts saying im gonna explode my new motor that i worked so hard for WTF! Had problems with power valves on my street car before when they go fuel keeps running into the cylinders and floods out the engine thats why i like to plug them, dont want to spend time at the track pulling the carb and repairing it ,ive read many posts on the internet by racers and carb tuners most do not use power valves for this reason one back fire and they could let go. But crack head insists i dont know what im doing
