Hi guys.

This is my 1st post on here so a bit of background first and foremost. I race at 3 sisters in the prokart endurance events. Done 3 races now and made improvements each time. At the last race the engines werent revving out.. we were getting 5300rpm at best on 20/63 gearing (see my team mate, bez1968's post). Thinking that the engines may be running lean at the top end I stripped the carbs off to clean and check jetting, but the main jets have no markings on them. How do i check what size they are??
