K guys. Fitted a set of IDF 40's to my 2L. There was a few issues - linkage is only opening the carbs up 80% I had the carbs balanced by my mechanic but he told me I needed a 009 since there was no vac advance So...threw in a 009. Currently I am lacking power down low and under load. If you just rev the thing standing still it winds up real quick but get it going and the 009 flat spot arrives. I was hoping that some other people on here with webers could give me an idea of how their 2L goes and possibly what settings (jets, timming etc) everything is on. Any idea why I have such a flat spot down low? the mechanic did note that the jets may be too large, but should be ok. What timming should I run? currently i have it set at 15 degrees as this is reducing the lack of power under load. Any recommodations on linkage? should i modify what I have or buy a new one?
