FWC Posted February 28, 2012 Share Posted February 28, 2012 I have a '70 L24, 75K miles, Nissan Comp. Autocross cam, headers, triple Mikuni carbs. My problem is that at light or steady throttle @ 3K RPM, I get a popping back through the carbs. Heavy acceleration at any RPM is good. Idle is good, no lean popping. Carbs are synched. I have used the search function and found peripheral information but nothing that directly addresses this problem. Any and all help would be great! Thanks.

JMortensen Posted February 28, 2012 Share Posted February 28, 2012 Sounds like you need larger pilots. Quote Link to comment Share on other sites More sharing options...
