This is an 1150 gas Dominator built by IRD carburetors, I pulled the bowls off and checked everything for cleanliness, it’s clean and ready to use depending on your tuning requirements, the documentation for the carb is in the first pic, this is all I know about the carb, it had maybe 10 passes on it after it was bought and was replaced with a 1250 IRD carb, any questions just ask and I will answer to the best of my ability, this carb is part of an estate sale that I am in charge of, asking 525 shipped and it comes with a 4150 to 4500 adapter if you want it, payment needs to be cash or postal money order only, thanks, pm me here or email me at alilblacktruck@gmail.com
