Ok so my polini kit will be here wednesday and I need some help. I have a 77 garelli gransport. I am getting the 65cc kit and for now I plan to run the stock 14.12 and intake. After reading everything about running lean and seizing I want to make sure it doesn't happen to me. I need to know a good basis for a jet to start with while tuning it. It had the stock 50 jet in it right now so I know that has got to be way too small. I am also running the stock exhaust with a drilled out baffle. Thanks in advance for any help you can provide.
