Odd one this, my lads '90 just would not move this morning after being stood for 4 days over Xmas.
When he tried to put the handbrake down, as he released it, it promptly clicked back on all by itself!!!! Looking under it while he tried gently to move forward, I noticed that the rear prop wasnt moving but the front one did and decided that the handbrake was probably frozen.
Has anyone else had this?? We finally got it moving, stripped it down and it seems the plungers and the rollers were well gunged up and I can only assume this was part, if not all, of the problem...
