chucknicc There was a change in the injection pumps on the later 1105 & 1135 that allowed for advanced injection timing, because of this they retarded the timing for starting, when the engine speed came up the timing advanced. This pump allowed the engine to burn cleaner. You may have bad injection nozzles or the injection pump may be getting weak. I doubt that you have any engine mechanical problems. I have an old 1135 with a lot of hours, it smokes until it is warm, but it always starts down to at least 20 degrees F. ,no ether. The Cav injection system won"t tolerate any air in the fuel system, the combines could be really bad, because they had to pull the fuel so far. They can suck air from a number of places and usually won"t leak fuel, but rather will let air in system which makes them hard to start and also allows the fuel to drain back to the tank. When this happens ther engine has to crank until the fuel is back up to the injection pump. A sympton of air getting into the system is that the longer the tractor sits the harder it is to start, then usually once started they will crack right off when subsequently started. They usually leak on the suction side. Check the screws holding the lift pump together. There is also a screen under the cover of the lift pump. There is another screen on the fuel tank drain plug that fits around the fuel pickup tube. Check the rubber seals on the injection pump and filter lines. Tom Dold
