Right after a trip to the rolling road for a fuel check and power run i returned with some bad news,i managed to get a max of 33 bhp at 1500 revs

before a fuel shortage,the guy recons its down to a fuel pump he also sugested to replace some sort of valve to help the breather system,he seems to think thats whats causing the smoke,think its a lack of vacume in the engine.
Any sugestions as to what kind of pump to replace the fooked one with?? Also can anyone recomend a place to get a 195 chip??
Thanks again Graeme
