top- this isnt body work, chopping up hotrods to make things fit. its a precision calibrated component. the recommended carb could NOT adjust to my idle calibration. my engine doesnt need 18 intial mechanical timming. that would hurt driveability and the vacuum advance's ability to alter timming for part throttle power. 18-20 inital will be hard starting especially hot.
i should have built my engine around your carb. that was your real recommendation.
