I've gone thru this JIKOV 2912 DC carb at least 5 times now. I'm getting kinda sick of it. I have spark, and compression, and everything is in order on the carb, but I just dont seem to be getting ANY gas to the cylinder. With the fuel line not attached to the carb, i have a steady gas flow, but when i attach it, the gas no longer flows through the tube, to the carb. ANY suggestions? I dont wanna give up on it, but I am about it. It will run for a few seconds on carb cleaner, and when i put gas into it manually.
