Hello, up for sale is a Quick fuel 650 cfm 4150 style used carburetor with a new rebuild kit and some jets and linkage extras. It is also electric choke. Good carb and was on a 440 engine a month ago but is not enough cfm for me so went another way. May need rebuilt to your standards. I will send USPS large flat rate with insurance for $30.00 in the U.S. unless you require a different shipping let me know. I can ship international but will need to check on shipping cost. I be boxed up well. Sold as is no warranty and know your application. Please email questions if needed. Thank you for looking.
