Also as Mark said, did you check the timing before you locked the cams and removed the old belt?
yeah i did, they looked about a tooth out when the crank was at TDC ( i believe its 2 or more teeth out and problems occur and one tooth out or slightly off timing just makes it run like a bag of crap.
IIRC the crank marking is on the face of the crank (once the pulley is removed) and that lines up with the notch at the bottom, while the cams sit with ther respective numbers aligned to the cuts in the rear belt cover. this is purely for a rough visual check, as i had to give the timing kit back to my colleague yesterday.
also. if the crank is 180* rotated while the cams are aligned would this make a difference? or is this very unhealthy for any remaining working valves (assuming any are damaged) :-?
PS. oh yeah, there was no damage to the belt apart from a cut about 2cm long paralel to the edge, bang in the middle, due to a rogue bit of the idler.
