stalln 412

Post by subrhyme »

Hi! I fire my car up and as long as I feather my pedal the car stays running. the second I take my foot off the pedal i cus off. It just refuses to idle. What could this be. I thought possibly timing so I undid the bolt and moved it a little to clockwise, no results, a little more and got worse. so I tried it counter clockwise and got the same results. could i be timing and I did'nt nail the exact spot or maybe the idle jets in my carb are clogged, what do you guys think? By the way I have 009

I take it this is he dreaded center mounted progressive? Check to see that its not flooding. Your float may be sinking...or a clogged idle jet. I would get rid of the 009. Its advance curve is not great for the type 4 engine . Either use the original FI dizzy or a 205 off of a bus. Ray

I hear ALOT of people are dumping their 009's and running back to vacuum dizzies.

i was told the 050 dizzy was one to use if you want to ditch the vac advance, but then this still doesnt have the perfect advance curve for the engine. i stuck with what the factory gave me.

Oh i forgot, always use a timing light, never adjust your distributer "by ear" easy way to junk your motor.

If you are using the 2 barrel holley progessive, the float is easy to change just by removing the carb top, the accelerator pump linkage and the small cotter pin (depending on the model). The floats are cheap. If the float is sinking.. ..change it. There is only one correct setting. Ray
