67 imperial holley carburetor issue

[78Brougham]

One of the first symptoms that reared its head in the fuel pump pushrod issue was increasingly hard starting when hot. I think it was a combination of vaporization of fuel in the carb after the engine was shut down and the fact that at cranking rpm the short throw on the fuel pump was having a hard time refilling the carb. At cruising speeds the engine turns enough rpm that the shortened rod can keep up with demand. The affects were most obvious during hot starts and under acceleration. My pushrod ended up almost 3/8" shorter from wear by the time I discovered it.

Thanks Matt I'll have to look into it in the spring, before I buy the eddy for it.

Ohhhhhhh... do you happen to know what the length is supposed to be? So I can tell if it's worn?
