Offending micro switch and new casing
Jim arrived on Saturday and fitted a new micro switch and freed up the plunger on the main control valve. All no w working well. I can recommend JIMMS.
Whilst Jim Paker (aka JIMMS) was with Albert he described a recent problem he attended on behalf of RCR. It turned out to be a very serious cause of prop-fouling that caused Maffi lots of problems. He also described a follow-on incident that befell a CRT tug and hopper.
