I am selling my 4150 that I took off my MKIII last year with about 3000 miles on it. Replaced it with a Barry Grant Mighty demon 850. Paid just over $500 for it, and am asking $300 plus shipping. If to much, then at least make me an offer. This carb is great. You can email me at [email protected] if you wish. I live in the Fresno, Madera area of Ca.
