One of the things I do when rebuilding a set of carbs is replace all the original Phillips screws with stainless Allens. I used to use regular Allens everywhere but have changed now to buttonhead Allens on the tops and sides, and regular Allens on just the bowls and that angle bracket across the bottom. I think the smaller, more rounded off buttonheads look better and blend in better with the carb body .....
So, with all the carb work I've been doing over the last few months, I thought it was time I made up a list so I don't have to re-measure stuff all the time, lol ..... and here it is .....
..... and some closer shots of the BS38 and BS34 sections .....
