Hi all, first time posting in this section so if I'm committing any party fouls feel free to comment.
Went through some experimentation before I figured my 67 Lane liked a vacuum secondary carb. The 750 was too much and the 600 was close but no cigar as well. They are not doing anyone any good collecting dust. Both worked as expected at the time I removed them. Posters here have a better idea what these are worth than I do so feel free to shoot me an offer at amdscooter@gmail.com.
First up is a 600cfm 4776c. Bought August 2017, probably just over a year. have original box & will include everything in photo (new choke cable & brackets).
Second is a 750 bought probably 7 years ago. Was in the car at least 5 years. If I can locate the original box I'll send it, no promises though as I searched the garage today and no luck. Will ship with what you see in photo, carb only.
