HELP bubbling gas in he carb!!

[Ponyxpress]

I have an issue I was hoping to get some guidance on. I have a 65 inline 6. Not sure of how many miles are on it. So far I have rebuilt the carb and replaced the coil. Both of which were needed, but have not completely fixed my problem. When I drive the car and she gets warmed up, she dies and there is gas bubbling in the card. The fuel lines are away from the block and exhaust, so I don't believe it is vapor lock. This past weekend, I replaced the thermostat, flushed the radiator system, and replaced with new radiator fluid with some water wetter. I haven't had a chance to drive it to see if that may have fixed the idea.

So my question is does it sound like I am on the right path?! If this doesn't fix it, does anyone have any suggestions on what I should look at next??

My 65 convertible is a 200. I've never had the problem that you are describing. Is the gas boiling away due to heat? That sounds scary to me! Does it appear that you have too much fuel in the carb? Did the problem begin after you rebuilt your carb? Is it an Autolite 1100, Holly, etc? Sorry for so many questions, but I'm trying to check off potential causes and then we can see where we are. I currently have a Holly 1bbl on my car, and recently obtained a rebuilt 1100 that I was going to replace it with. Now I'm seriously contemplating buying one of those new Pony Carbs upgraded "Vaporizer" 1100s. I've heard some early good reports about this reproduction. Anyway, I hope you can figure out your own carb situation soon.

Good Luck, and keep us updated!

Oh yeah, a couple more questions; What does your temp gague indicate before she dies? If it's hot, have you considered a new radiator as well? I switched from the stock 2-row radiator to a 3-row replacement that fit spot-on. I was impressed with how much cooler my car ran.

Also, check out the thread in this forum. Does it sound like what you're experiencing?

Good luck!

I appreciate the reply. The carb was doing this before the rebuild, that is why I did the rebuild. I had read it may be a problem with the choke. I rebuilt it, and it seemed to cure the problem for a while. Then I found out the coil was bad as when the car was warm, it wouldn't run right. So I replaced it, that issue was gone. The bubbling reappeared when I began working on the cooling system. And I think it may have been operator error. What happened, I had the flushing fluid in the radiator, and may have taken it for too long of a trip. That is when the bubbling reoccured. I have flushed the cooling system, replaced the points, distributor cap rotor button, thermostat and radiator cap. It seems to run a lot better, but I haven't taken her for a long trip yet. I'll let you know how that turns out. Again, thanks for the help, I was about to lose hope for this forum.

Anytime! I'm good at passing along other people's sound advice :D Please be sure to give an update on the problem, whether it improves or gets worse. I'd like to know how to handle the situation if my 200 starts acting up :D

Good luck and all the best!

Well it looks like I have resolved the bubbling issue with the card. The only problem now is when it gets warmed up, it runs horrible. Rough idle, acts like it is missing. I have replaced he distributor, rotor, points, coil, and fuel filter. Any ideas what I should look at next?

Thanks again for the help!

How about the timing? Have you considered ditching the points? I replaced my points with the Pertronix Ignitor a while back. Have you pulled your plugs to see if they're all firing the same? They should all have a uniform appearance. http://hawkworks.net/sparkplug-chart/ If you have a gunky looking one, that might be part of the problem. Also, when was the last time you changed the plug wires? Any one of these could contribute to what youre describing. If you've already addressed these issues, then maybe it's time to look up a good mechanic. hopefully, one who won't try to get you to replace the motor, like one tried to do to me a while back!

Good luck and keep us posted!

Sounds to me like too much engine heat is being transferred to the carb, and the most likely way is from the intake manifold to the carb base. If it occurs only when sitting still, it could be from heat rising off the exhaust manifold. Is there a spacer under the carb? Should there be? How about a heat shield. If not, maybe a thicker gasket, or even two would help reduce heat transfer.

I finally got a chance to get some of my neighbors tools to take a closer look. It appears the Timing was WAY off!! it was striking right at the 12 o'clock position. Not even on the timing marker that is about the 230 position. I adjusted that, removed the points and went with the petronix. Once I did that, I readjusted the carb, and WALA! It appears to have fixed the problem! I am going to try and drive her a little further tomorrow and see if that fixed it. Thanks for all the help!!

Congrats for sticking with it and solving the probelm! Spring is just around the corner, happy motoring!!
