Fouled Plug?
I went out last night to start my 2001 400 and it wouldnt start
chocked it and still nothing. Checked the plug and it was wet.
Dried it off and put it back in and nothing. Put in another plug
and it started right up! My ? is im running a 152 main jet with stock settings. I put a FMF Powercore 4 S/A on a couple weeks ago with 4 1" Uni vents in the airbox with a Uni filter. My head pipes turned a little blue ever since i got the machine (running lean i guess) and spark plug was showing a little white. How can i be fouling plugs now and I have noticed a little bit of a backfire when started
but goes away? I totally confused back fireing and blue pipes means running lean, but fouled plugs means im too rich? Any help here would be great!
