Help! My beloved Yogi -1973 campervan- has a broken engine and won't go :-( think it's a piston but may be whole engine. Only had van since August and broken hearted can't use it at moment. Can anyone recommend anyone local to me who can come to us or who can collect the van to fix it as it's not driveable... Live in Daventry Northamptonshire. Thanks in advance, new to all this and appreciate any help.
