I'm having a problem with my 2 fa50's. I cleaned the carburetor really good twice on both, new fuel filter and threw out the old inline ones, drained and replaced the oil and gas, new battery, new fuel lines and vacuums, replaced the CDI, reed vales, piston, cylinder, hot tanked the exhaust, k&N air filter and a few other things. I cannot get it to run good when i give it WOT, it idles fine and only works somewhat well with the choke on. I also ajusted the needle and replaced that also and switched carbs.
What do I need to do so it will run right. Top speed of 24 right now but bogs down intermitently. PLEASE HELP!!
