The question is why does the horn sound constant, I understand it can be a overheat or fuel, I disconnected the vro system> Can it be a vaccum line, I replaced the fuel filter as well. The engine is peeing fine. Please let me know
Take a look in the manual if you have one.There are a lot of different things and each one has to be eliminated. If not you can go to the library and read and copy for free or 10cents a page.
I looked in The Clymer manual for that engine and it sez hi temp, low oil and fuel vacuum will sound the alarm so it's one of those three conditions or one of those switches is bad.<br /><br />c/6<br /><br />Hooty
