Cheers Danny, I was thinking about doing that, but what about re-tensioning the belt etc? In theory it should be tensioned correctly if the pump is in the exact same position as it was previously shouldn't it?
A couple guys on the IDI Derv forum have figured out an easy way to set the timing using an M8 x 1mm x 50mm bolt which doesn't require a dial gauge, just the bolt & a disc with 100th's to indicate timing advance... but we're still waiting for the guy who developed them (and the diesel resistant indicators on the disc) to start making them, which won't happen till the new year I think.
Just read a post on the derv forum, the guy who was going to make them had a hissy fit because the guy who originally thought of the idea wanted his 'slice' of the profits, which there were going to be none of. So there goes a cheap timing tool. Bugger.
Anyone want to get a load of M8 x1mm x50mm bolts, add a pointer and a separate indicator disc (in 100th's) and create a timing tool for IDI engines, there were plenty of people who wanted them on the IDI forum.
