So I received my 65cc Metra today and installed it. I slightly cased matched it and am now in the tuning stages. I need your help. I have a 1978 JC Penny Swinger E50 engine, bi-turbo pipe, 14 bing and high flow air filter. When it was stock I ran a 66 jet in there and it was awesome. I mix 32/1. I have bing jets from 60-80.
With the kit I started with an 80 and tried all the needle settings with no luck. It was not starting on the stand, only when I pushed it and would hold full throttle, the plug was black, and could not hold any idle. I then put in a 78 and tried all the settings, still wouldn't start easily and it bogged until 15mph. That plug was running lean. I am assuming I have an air leak and will be checking tomorrow. So what I'm getting at is if you have a 14mm bing with a metra kit on it, what is your jet and needle setting?
