would be the carb that he is cursed, er, stuck, aah has on his 73 280. More tempramental than my ex-wife.
But, as long as it isn't warped, I guess its rebuildable...kits can be had for just under 70 bucks.
I am still looking to "rent" a Solex for my 73 280 that I sold to a guy in Texas. I just need it to get onto the transporter, and back off again. Maybe 5 or 10 minutes of actual use.
Good Luck with your restoration, and watch your head when your under the hood!
