I posted earlier this week about my B-450 that was smoking terrible and had raw diesel out exhaust. I bought this tractor from a older man who used it right up to the time it was retired. It has been setting 10+ years. Went through the engine, rebuilt the injectors, and cleaned and re sealed the pump( did not take it off the tractor) Well it started easy and had 325 psi compression on all 4 Timing on pump made no difference. Im a decent mechanic but this thing wore me out. Here is the problem The drive coupler on the injection pump has one small 3/8 notch that the driver fits into. At some point this broke allowing the pump to turn about 45-50 degrees. Timing was retarded so far that it was injecting diesel on the exhaust stroke. Im still not sure how it started so easy. Next time dont always believe what you hear. I know now why the tractor was retired!!! She runs good now though and NO SMOKE
