Back on this project again now...... Jim has the gearbox and new bushes, so hopefully wont be too long before I can start putting the actual tractor back together........ In the meantime I've had to repaint the fuel tank!!! I had brush painted it about 6 to 8 weeks ago, once dry I put it indoors to cure and harden thoroughly in the airing cupboard. My paint supplier sells a 1K clear lacquer which is fuel resistant and I planned to lightly dust the clear over the brushed fuel tank to prevent fuel spill damage...... However when I applied the 1st light coat everything was fine, I left it 15-20 minutes and started to put a 2nd light coat and there was a bit of a reaction! The green blistered and peeled like latex, leaving the etch primer undamaged and exposed!!! So...... I had to start again, rather than risk problems again, I bought a can of 2K BS282 Forest Green. At least this is fuel resistant as it is! And there was enough in 1 can to paint several coats on 2 fuel tanks (1 spare) the air shroud inside and out, the tank brackets, the engine brackets, back plate and chain cover both sides and the handlebar swivel mount!
Here's some pictures of the Villiers MK12 engine with air shroud and fuel tank all refitted.......
