He removes side panels and the steering column shroud to access the throttle linkage, then adjusts a compression spring using two 14mm wrenches and applies WD-40 gel. Practical and step-by-step; best for B2601 owners facing the same drifting throttle symptom.
An owner-operator sharing hands-on DIY repairs and projects from his own 33-acre property, so expect a practical, non-commercial perspective.
The owner found a compression spring on the throttle linkage had weak resistance, causing the lever to lose hold at wide open throttle needed for the 540 PTO mark.
Remove the side panels and steering column shroud, then use two 14mm wrenches to loosen the lock nut and tighten the compression spring about a quarter turn.
Two 14mm open end wrenches or metric adjustables, since there is not a lot of room to work in the linkage area.
The owner avoided full lubrication to prevent looseness, but applied WD-40 gel to one friction point he identified as a wear point.
