Cornpanzers Riv

Me as well, but that was the first thing that I replaced when this problem started.

Made some progress today. On a whim, I clamped off the return fuel line and took it for a long drive. Ran great, no surging or starvation at all. of course, this leads to a couple questions. First, The car no longer has air-conditioning… What was the purpose of the return fuel line on air-conditioning cars in the first place? Second question… What could be causing excessive fuel to return? Perhaps float level? third question, what prevents me from just disconnecting the return line and moving onto the next challenge? (I typically like to find root causes, but if this works, I’ve got plenty of other things I can be doing.) as usual, thank you for all the help.

I have not, but the problem existed before, and after I bought a brand new pump from Napa. Doesn’t totally rule it out, but pretty much.

Swapped out the coil today. Went for a drive, and was pretty excited that it seemed the problem was solved. I was even able to get into the secondaries. Unfortunately, it only lasted a couple miles before the problem started up again. (I did also confirm that the fuel lines in the rear are new.) I’m pretty convinced it’s a fuel issue. It surges like it’s running out of gas. Typically ignition problems are more abrupt. I could be wrong though. It’s happened before, LOL. I will buy a points and condenser to throw at it just to cover my bases. What’s interesting is it’s dramatically more evident when I’m driving uphill. Even at slow speeds and part throttle, long gradual grades trigger the problem immediately.

All great tips. Yes, I was last guy to work on the ignition. I did rebuild the distributor, but it was long enough ago that I don’t recall if that was when the problem started or not. I’m happy to throw some points and condenser and a coil at it. That would be a simple fix, thanks for the advice

Yes, I do have the stainless plate. Thanks

Great tips gentlemen. I appreciate all the input. I’ll check the coil this weekend and get it up on the lift and see how the hoses look.

Good suggestion, but the tank has been drained. It’s clean

It is the original Carter.

Hmmm…good tip Tom. I will check that out next weekend David

I have a 63 with a 425 and turbo 400 out of a 64 Riviera. I have chronic fuel starvation issues. If I try to accelerate quickly, it starts to surge. Get into the secondaries and forget about it. Seems like the problem is worse climbing a hill. I assume that’s due to the load and not the inclination. I have replaced the sending unit, filter on the unit, fuel pump, fuel filter and rebuilt the carburetor. It was originally an AC car, so it has the fuel return line. I have not replaced the lines. Any suggestions? I’m tempted to install an electric fuel pump, but that seems to be a Band-Aid not the actual fix.

Thanks Tom

Missed this. Tom, you have a message

Did a major addition to the home this summer which included an additional 3 1/2 stalls in the garage. Therefore, I was finally able a couple weeks ago to bring the White 63 home from storage and park it next to the Silver 63 I picked up a couple months ago. That’s a great feeling!

Still looking. Thank you

Tom. Message sent. Thanks

Thank you Gene. Please take a look for me.

Wow, thank you. I looked at their website earlier and didn’t see those. Really appreciate the help.

I have a set of foam cushions for the front seats from Clark’s, but can’t find a source for the rear seats. Anyone got good suggestion?

Surely someone is holding. Still looking for a brown steering wheel. thanks

Would like to buy a nice steering wheel. Anyone?

Some of you “senior” members may remember John Trewatha and his Silver 63. Well John is still doing well, but getting up in years. He contacted me and wanted his Riviera to go to a good home so tonight I brought it home to my garage. It’s a beautiful car and I’m thrilled to be the new caretaker. Originally a northern California car, it ended up here in Ohio somehow. It was originally purchased by a fairly famous professor at Stanford University. John restored it in the late 80s and added some very cool factory options. More later…

Here is the new addition. See my other thread for more details

Been a while since I’ve updated. A lot of stuff going on and the Riviera has been back burnered for a while. Interestingly, I was recently offered the opportunity to be the new caretaker of a silver, with red leather restored 63. It was a deal I couldn’t pass up, so the white car will likely be for sale. Really struggling with the decision…

My apologies...this is long gone. Thanks
