St-Eugene, Ontario | Usually rebuild around 15-20k hours but earlier on we had more problems and ended up having to change heads and pistons more often. We have a better fuel delivery system now that reacts quicker to adjust to changes in gas quality, the old one was less precise and slower to react and this sometimes meant overfueling which caused us problems. Gas quality can change for us depending on off farm material we get but we are also now much pickier about only getting in the same stuff week after week so we don't have any surprises. | |
