Robert U’Ren shares some of his helpful fixes and tips on buying, selling, repairing and recommissioning World War Two and Hotchkiss Jeeps
As soon as the seller took me for a drive in his beautifully restored Hotchkiss M201 Jeep, I was aware of a slight misfire when coasting as well as a little spitting and misfire on idle. It seemed to clear itself immediately when under acceleration, so I didn’t think it could be too serious.
When I got the Jeep back to my workshop and started to investigate, it turned out to be a real head scratcher. A simple misfire can be caused by so many different problems, so I tend to check or replace the most predictable causes one at a time until the fault is found. I started by checking the tappet clearance in case a gap had closed up, preventing a valve from closing, but no faults were found there.
