I have a 2001 660 and it wont start. I checked the plug and i had good spark but it does not seem to get any fuel. I cleaned the petcock and gas comes out of it but when i take the carbs apart they are dry. So i filled the fuel line up with gas and treid to start it and the level never drops. Kinda new to carbs so maybe im overlooking something. I see that some people have replaced in line fuel filter but i dont think i have that.
