dont waist your tim eon the dizzy
sounds like your valve timming is a tooth or so out.
I have enought pics to do a DIY, but im not brave enough to make a DIY as I feel it would do more harm that good if peeps start trying to do there own belts. for a good mechanic the timming belt on a civic is easy. but I have seen non honda mechanics get it all wrong because they used the red timming mark on the pully as TDC when infact you just use the marking on the crank chaft timming belt pully.
also a tight timming belt doesnt snap timming belts, it snaps crank shafts so be carefull.

let me know if you want help on getting to the timming belt to fix this with your tafe lecturers.
