pilot scew falling out??!? My bike is a one of a kind

[1980ATC185]

i wonder if anyone has ever had a problem like this
i got this old atc185 running by rebuilding the carb and cleaning the gas tank and air filter and putting a new plug in it

then it ran pretty good but fouled the plug after a day of riding

then i noticed the new pilot jet screw i put in must of fell out while i was riding

so i put in the old one and it ran great

then the next morning i go for a ride and i go to start it and the cord came off in my hand but it the bike was running so i dropped the cord and rode/mudded it

so today i had to pull the cover off and cut and stick the old rope back on there and i noticed the dam pilot jet fell out!! the bike runs but now it fouls plugs

plus that was my last pilot screw

does anyone know where i can get another pilot screw?

This happened to me, it didnt solve the problem, but i didnt lose anymore jets. I just tied some fishing line around the jet a few times then tied it to the frame somewhere. So when you notice it running bad just check it, and if it falls out it'll be hanging on the string so all that you have to do is screw it back in.

I'm sure there should be a little spring that goes on the outside of this screw, this acts as a device to stop it unscrewing.
a Honda dealership will have a jet and a spring.

thanks for the help i never knew there was a spring there ill have to order a spring off the net because the local honda dealer charges too much

You dont mean the pilot jet, you mean your pilot air screw right? The one that you can adjust externally, there should be a spring there which will keep it nice and tight so it wont vibrate out.

In the book they call it a pilot screw assembly
