I've been thinking about swapping my stock carb. 1985 720 4x4 with Z24. I've heard good about both the stock and Weber and wanted to gauge some current opinions. What do y'all have (stock, Weber, etc.), how long have you had it, has it impacted your power, fuel economy, etc. Any info would be a huge help. There's a K646 kit online for $300 even, includes a genuine electric choke Redline Weber, adapter plate, linkage kit, and air filter. Also thinking about an MSD ignition box. Any comments on that as well would be appreciated!
