In a similar vein ....... Tried to do something about the appalling fuel consumption of the Mirage ( that useless leaking fuel cap every Italian manufacturer seemed compelled to use at the time didn`t help either ) ....
It was usually 32 - 34 mpg , increasing to around 28 mpg when cruising at 6000 rpm .....
Took a look inside the carbs ..... Found 145 mains , and K1 needles ( OK - Mirage spec ) ....... but pilots were 65 ( standard 1200 ) ....... should have been 55`s .............. either fitted in error ( or rather , just left in place in error ) , or maybe just left in place to improve low speed running in case Massimo suddenly appeared and decided to take it for a run around the test track ....
Thought I would try to improve things by fitting 55`s ..... as pilots are running all the time ( I think ? ) , smaller ones should help ........
I was also thinking about slide cutaways , but that was starting to get too complicated , and I couldn`t be bothered with all that .......
Richard didn`t have any 55`s , but he did have 58`s .... so those went in ......
Didn`t seem to make much difference ...... I asked Richard about K14 needles ( standard 1200 ) , as these have slightly larger diameter , and shorter length taper than K1`s , but Richard reckoned if I fitted those " I wouldn`t get to the end of the road " ....... maybe a slight over statement , but I guessed he would know better than me ......
Eventually got 55`s from Richard , fitted those , and turned the accelerator pumps down to almost off , which resulted in an improvement of about 5 mpg overall ........ Also ended up with 118 mains in place of the 145`s , not that that would make any difference most of the time ......
