About Tom Langdon, I think it's wonderful the way he supports the hobby. He won't hesitate to call you back, and was always helpful. I really like the guy, myself. And if it weren't for his carb options, which are by the way really very inexpensive, the stovebolt engines would have that much fewer options other than the antique Rochester 1 barrels.
Just a vote of confidence here for Mr. Langdon.
I agree. I haven't been all that happy with this setup either for the reasons mentioned above. It seems I had most of these issues in getting mine to run. I think I'm close now. My point though is that Tom is very approachable and responsive. I liked working with him and appreciate his dedication to our hobby.
