Fool Throttle
07-15-2006, 06:20 AM
Ive got 2 probs and needed some help.
1. i have the 427 chevy, Vitor jr intake, 830 Holley race carb. MSD dist w/ vac advance (but its unhooked). boat turns 5100 rpm at full throttle.
the problem is every time i go full speed for more than a few seconds and back off to an idle, the boat runs extremely rough and shakes like its only running off 7 cylinders??? it wont even idle below 2k and if it dies, I have to hold the pedal to the floor for at least 5 sec until it starts. If i keep it about 2k and then take off, it runs great just like normal, but below 2k, its like a plug wire comes off or something. If i let the boat sit for 30 min, or if i run the boat for 30 min around 3k, it fixes itself?
Could this be a problem with the vac advance dist? As stated above it is unhooked but i wonder if air could be blowing into the vac advance nipple and changing things? All plug wires and plugs look good.
2nd Problem. also after doing a full throttle run, there is a lot of oil that has sprayed out of my breather. The PCV valve is good and hooked up correctly. The filiter in the breather is a K&N billet and is good too.
Thanks,
Jay
