all i can say is WOW. i think you hit the jackpot there. looks very well taken care of.
with a little minor work could be a really special car.
am very happy for you, and the gamble looks to have paid off.
regarding the hard to start issue. again i am sure this is servicing, and a little more use.
possibly coolant temp sensor too, as maybe its not getting enough fuel to begin with.
anything on the VCM?
what i would do straight away is check the rotor arm. if my one is anything to go by. any signs of melting or burning, change it.
its worth changing it anyhow, i reckon, unless its very new looking. also the dizzy cap gasket, and vacuum line air filter.
see list below/ (see my shadow thread)
does the air con work too?
looks like it has a service sticker there, so must have been done at some point.
also, to save you some time, here is a little list of part numbers. could come in handy.
