Re: Fwd: [Chrysler300] carburetor

[Robert Merritt <okbobwynmer@xxxx>]

Another good reason to go to a Carter instead of Holley is safety. I have seen several Holly-equiped Chryslers have damage from under-hood fire caused by leaking tubes on Holly carbs. I have personally bought a 68 and a 69 300 from insurance companies way back in the early 70s because of this problem. Both were cars that had not been started for some time and the o-rings on the fuel tubes between the front and rear fuel bowl had dried out and dripped on the heat riser portion of the intake manifold and caused a fire. The 68 was in a garage and was extinguished quickly and was repairable but the lady owner of the 69 was driving at night about 10 miles from help so she got stopped and got out safely and watched it burn. Has anyone else had this problem? I haven't because the first thing I do when I buy a Holley-equipped car is replace the carb with a Carter.Okie Bob

I have done it to several that came with Hollys, couldn't wait to
'throw' them away.
Good luck.
