Ok, this is a weird one.
My 74 duster was starting and running fine last week. Two weeks ago I think I flooded the engine, and after it sat a while it fired right up. The battery was tired, so I changed it out. Now this week it doesn't start.
Now here's the strange part.
When I try and start it, it roars like it's actually catching and at pretty high revs, but then immediately dies. I do it again, and same thing happens. Roar, and quit.
Now the first thing I thought of was to check the flooding again, as it's a Holley double pumper with line pressure around 7psi, which I know is too high. I bought a regulator I'll put inline. I pulled the plugs (they didn't smell too bad) and pulled the carb to help dry it out, but now I'm thinking it might be more electrical and perhaps I have a bad ignition switch which won't work in the "run" position.
Anyone know how I could diagnose this ? Or have any other thoughts why the car would start but then quit when placed in run ? The previous owner hacked the wiring pretty good, so I'll change that out shortly, but wanted to get your thoughts until then.
Thanks FABO's.
