Yesterday I blew a bulb in the front turn signal lamp. I did not realize it for a while and thought I had something wrong with the MSD box. What was happening was I was hearing a clicking noise inside the distributor. I did finally fond the blown bulb and replaced it. Once I did that the feedback went away. Essentially what it looks like is the blown bulb was grounding out the system. Now is this normal or do I have something wrong?

A 'blown' signal bulb should not have any impact on the ignition system. Something is not wired correctly with the signals or you selected an inappropriate line to hook-up your MSD box.

 

Took the Vette out on one of these rare occasions and as always it runs great for a while and inevitably something happens!!!! Rodae around for about 15 minutes in light traffic and about 85 degree weather. Stopped at a buddies house and stayed there for about 20 minutes. Headed for home about 10 milles away. Halfway home the engine starts to symble and chug. Pushing on the pedal seemed to kill it faster. dropping it down in 2nd and putting it under a load would let the engine come back a little. This went on for about a mile with a max speed of 10mph. It then got so bad that it finally cut off. It would fire right back up but when I gave it throttle it was like there as no gas. Now I am moving about 100ft and dying, 100 more and dying just trying to limp it home. Finally dies and I get out and go under the hood. Pump the throttle linkage and the squirter spits a little then nothing. I am getting a full squirt from the secondaries. I crank the car up and it runs rough. Watchung the squirters in the front I am seeing no fuel. manually opening the throttle I am getting spits again. Now I am thinking maybe stuck float. Having no tools I pull the rear veiw mirror out of the floorboard where it fell off earlier and tap all over the front bowl. At this point the car has been sitting for a coupe opf minutes with the fans running. I get back in the car and it cranks so I take off. It stumbles a little but then cleans out. I am thinking ok it was a stuck float. Make it about 1 miles and 200 yards from home and it starts doing it again!!!!!!

This is an 850 Mighty Demon on a solid cam 454. I pulled theEarl's filter and it was clean. Pulled the float bowl and the float appeared to be fine. So is it vapor lock???? If so what can I do to help this? I am running a heat sheild under the carb and a full K&N extreme air filter and lid settup. Some one had suggested that I might have the fuel going through to much metal with the braided line going to a AN elbow to coupler to earl's filter to coupler to dual feed line.

Help please!!!!
