hi - i have a H22A with a manual g/box behind it - as soon as i got it i changed all belts/tensioners, and when i took the old auto-tensioner out i saw it was completely stuffed - all has been changed now, but it still wont idle right - when stop start driving, when i put the clutch back in it dies right down before coming back up to normal idle - i thought that perhaps the timing or balance belt could be slightly out - anyone have any suggestions? cheers
