I don't really know much about carbs either, but I do know most people will tell you that the fact that it's a 4350 IS the problem. An upgrade is probably in order as the stock carbs were horribly inefficient.
Thanks for the encouragement, I appreciate it. A quick question: do you know whether the the needle valve has any rubber on it; i.e. is there hope of getting it clean without having to tear it apart?Sounds like an overhaul is due! I know times are tight and these damn vehicles can be trying but stick with it, it will be worth it when you get it done. Try Northern Auto Parts for the rebuild kit they have great prices. You have 2 carbs so you can tear one apart to familiarize yourself with the internals before you rebuild the keeper.
Mark, it's still under the hood mainly because of convenience. It'd be a bit more complicated to mount it on the frame rail what with the hard line under there too. I'm going to get the eccentric mounted on the front of the cam and install the mechanical pump ASAP anyway so that should be one more thing out of the equation.Any reason your leaving the fuel pump under the hood? I'm about to put on an electric fuel pump on our 78 Quadravan and I was planning on putting it in the frame rail just in front of the tank selection valve which is just in front of the mid tank.
Underhood temps on the vans is quite high plus from what I've "read" the electric fuel pump like to "push" the fuel, not pull it anyway.
Yup, thats me.. Good 'ol lego motors..Mark, are you the guy with the "Lego Motor"; if so, you're a huge inspiration. I don't suppose you have a picture of how the kickdown cable is connected? I bought a premium factory pump so I thought that'd be the way to go. At this point I'm drawing at straws so I'll reset the float level then it's going to the mechanic if it kicks the bucket again. I've actually had zen-like patience with this thing because it's so cool and I have a vision of what it's going to be when I'm all done. I'm starting to near my limit though...good thing I'm still under $2k into it.
