Stock carb jets for invader 440

when you get the mag seal out it will be apparent why it won't run right.

Just thought I would throw out an update:

Carburetors have been fully rebuilt, all new gaskets, o-rings and jets. I found out that a small round style main jet works as a replacement for the econo-jet. I ordered a Mikuni  part no.  # N102.221-120 and its exactly the same as the jet I pulled from the carb.

 I am in the process of replacing the crank seals as you guys recommended. I split the case and removed the old ones tonight and what did I find?
The mag seal was in terrible shape, just as kawhead predicted. Im glad I took everyones advice and replaced these seals now.

Hopefully this weekend I will be able to tell you guys the sled is back together and runs like new.

You got lucky , sometimes those springs get sucked up into the crank or top end .  I've seen it go both ways unfortunately.

a lot of your problems will now go away....it'll start warm with a small tug and idle nice....way to stick with it,half of fixing stuff.
