I dunno I can rebuild a core for Around $100 which is a heck of lot better than "under $1000" plus it's simple to use. FI doesn't magically get you 5-10 mpg over a well tuned carb. I've seen plenty of well tuned carbs get well over 20 mpg. Its called overdrive, gear ratio and proper AFR. I guarantee he can get over 20 With THAT overdrive transmission. Do you know my age? Do you know me? Do you know what I have or have not done? Did you know that I was a mechanic for a $120000 engine for a 45 million dollar piece of military hardware? No I guess not, you just "assumed" that I'm an inexperienced kid. But I guess some of these folks on this forum or the older guys (my father included) who have been teaching me don't know Jack because you know they were tuning carbs before you even owned a car. But hey what do I or they know?... I'm done with you. You can keyboard commando all you want. You'll be on my ignore list soon enough.
