That's really cool. Thrifty and smart.
I have a customer with an 1835 sandrail I work on from time to time. It had a badly worn single progressive carb on it. I replaced that with a dual Solex 35PDSIT kit from John Connelly, among other parts. He jetted them for me and honestly they ran awesome out of the box, all I did was synch them and set the idle mixture.
I bought my recent rebuild parts from him, Mahle P&C, Total Seal rings, etc.....I love the Total Seal tapered ring installation tool. SO EASY to get the pistons installed. Used that on my motor and Brian's 2332.
The shipping is sometimes excessive but the parts are always right. Thanks John.
