Massey 1155 injector trouble

farmer-chad · Oct 6, 2012

Massey 1155 with perkins v8 has been running rougher and rougher this last year, kind of acts like it is being over fueled. Now when above 1700 rpm it starts a constant miss-fire and back fires so bad that flames are shooting out the stack. The back-firing and missing is at no load at higher rpm's, when pulling the miss- firing doesn't seem as bad, but hard to tell. Oh yes, there is lots of smoke, it has always been a smoker but now it looks like it's burning coal with any load at all.

The CAV rotary pumps were fair at best. You probably have injectors that are not atomizing the spray properly, but I would bet the pump is where your problem lies. I can't tell from your post how it starts, but you may have a valve burnt as well.

Pull the air cleaner element and see if that changes any thing. Exsesive exhaust will plug the air cleaner element. BTDT

I would double check the injector pump timing also.
