I tried to write above so anyone searching MFI could read between the lines. I guess not so here I go. Nigel has a 72 pump with an issue. Nowhere is there any mention of AFR, injector or air flow testing. The only thing we got was a guesstimate on the rack. Perhaps the space cam is out of spec? Who knows?
My mechanic shook his head and asked why don't go EFI, cheaper and easier. I'm a purist so went the whole rebuild route. That includes dyno testing. These are, mine included, over 50 year old pumps. Things wear out.
Nigel, you will always get a backfire if you drive hard.
