yeah, let me know. the carb I got had the jets broke off in it. So they are non-adjustable at this point. My buddy took them out at his machine shop but now I have nothing.

ok so i think stock the come with the 38 pilot and the 148 main. but alot say go from 38 to 40 and the maine to 150 if not more.

for the 38 and the 148 its costing me 5.29 and thats being straight up. so work with me. i can get almost any get for within 10 cents of the prices for these so if you do research and decied you need slightly different jets than the 38 and 148 tell me and well work toghter on this. throw a few buck in it for me and its a deal.

let me know

the 400ex's main jet is either a 148 or a 142 it depends on the altitude. i do believe. live in south florida and put the 142 in and works great.

Gets cold here? I know right now the 400 I have wont start?

[swamprat250r]

it doesnt have anything to due with how cold it is. it has to due with elevation. because the higher up you are the thinner the air gets.

In that case could it be a valve issue not opening properly?
