My lad is an MOT tester but doesn't have diagnostics.
There's a brilliant garage in snozzle that I'm sure will be able to sort it, but I can't find details till the morning.
My Grandad used to have one just like that. It was a bit of overkill driving his saw bench via a flat belt.
We never stalled the engine, but we made the belt fly off many times. I got good at putting it back on "live".
It turned out fine in the end. He's a good bloke but a rubbish business man. Best thing is to speak to him on the phone - he doesn't do e-mails or texts very well.
You've put the wheel boxes in upside down.
Did the same thing myself many years ago and joined Landyzone whilst seeking an answer.
Fella named Grunt (anyone else remember him?) came up with the answer.
I grew up in Little & Great Waltham, but I went to the Grammar School and my Doris came from Chignall Road.
Still got loads of relatives there, but we escaped to Cornwall in 1984.
