No power on hills

I recently bought a 5 speed manual 88 Mazda 323.  I have done a complete engine tuneup, however when driving on flat car works well but when going up hill the starts to die and I need to change to first gear.

what gradient hills? just gentle slopes or fairly steep climbs? i had this problem, turned out to be a worn out clutch. got a new one and now its fine.

cheers

mostly on steep hills.  But the guy who I bought the car from said that he recently changed clutch and disc. 

Dear friends

I can do only one thing for you,
you can down load very rear workshop manuals (If you going to by these manual you hac=ve to pay more)
and after that you can try to solve your problem yourself.
