2003 honda 400ex … New to me sat for 2 years clean tank took carb apart… but it jas a foam filter and two bros exhaust… the foam filter isnt right is it? The idle is set all the way up.. only will idle woth choke on.. i took carb aprt sprayed cleaner trough it…

In the float bowl is the idle jet next to the main jet.. the idle jet is smaller and has about 8 holes trough it?.. i treid to slide a small paper clip through it would not go.. couldnt see through it… do i have the right thing is this the jet…?

400EX seems to be running super rich alot of backfire out the exhaust 2 ft flames… it will run with choke off but not idle… the carb seems to pump alot when its idleing with choke on… where to start…

It ran fine before it sat.. yes i know there are a thousand threads… my main question is the thin foam filter?
