Clog ?

[mercrazy]

On my 260, the hose fitting in the horn that connects vacuum line to ecu gets clogged up all the time. What causes this? Is it from leaking reeds letting fuel/oil spit back into the horn? If not, how do I prevent it?

do you have the horn fitting that is very small internal diameter? I know some have a bigger internal diameter hose fitting on the horn to go to the ECU, some have drilled it out bigger also to help keep that from happening. And I would check you reeds also, it should not have that much oil in the horn to clog it all the time, but again, if you have the small hole in that fitting, take off the horn and make it bigger.
