It's a MK1 so i would say he won't have a problem with pulling the dizzy
As clanger said...from MK2/3 you don't need to unbolt the engine or anyting like that....just pull the rocker cover off and then undo the 2 bolts on the top that holds the dizzy in place and lift up

I would say it's your fuel pump too
Are you running any surge tanks etc?
