[QUOTE="philstar, post: 637346, member: 17600"] After another MOT fail on the T4 and loads of welding I'm finally back on the bus. First of I set the valve clearances again—they were all fine. Then I attempted to set the timing with my new timing gun... got it bang on for 7.5dbtdc on idle, however, I am getting ZERO advance whatsoever when I give it any kind of revs. It revs sweet as a nut all the way up to 4000 rpm (once it's warm), but the pulley mark stays over to the right and doesn't budge (air cleaner removed, vacuum hose unplugged from carb and capped, corresponding carb connection capped, both connections on manifold capped). I performed another compression test (albeit with the engine slightly warm) and once again it's spitting out 25psi. I was hoping to have this bus for my own wedding (in 3 weeks' time) but I really don't think it would make it. What's my next move? Do I abandon all hope and pull the engine, perhaps aim for BugJam?
