![]() ![]() I forgot about this and haven't tried the wipers since the rebuild. After the backfire, the wipers had trouble getting up, hence why the vaccuum advance is drawing my suspicion so much. You will probably need to change filters 3 times to get past crap out of system I forgot about this, but yes, the vaccuum is connected to the wipers. You will need to change all the old rubber lines to new lines compatable with todays fuel Is the distributor vacume line hooked to a carb venturi port?

While you're in there trace back every vacuum line to be sure that nothing blew off with the back fire, and if you find any hoses dry and cracking this is the time to buy ten feet or so of new hose and replace all of them, one at a time. You run on one 2-barrel for economy, then have four secondaries to come in when you need more power. You probably already know, but it's worth saying that your center carb should be the only one with an idle circuit, with the two outer units serving as secondaries, only coming into play when you get into the throttle harder. Then after it's all clean and dry re-assemble in a sanitary area. After you soak the carbs you'll want to blow compressed air through all of the passages to be sure they're clear. If you don't have an inline filter then you probably plugged the screen on the inlet to the carbs, or may have just pumped the sediment into your float bowls where it's partially plugged the jets. Blowing back through the line with compressed air towards the tank would be a really good idea. If you haven't changed the filter that's the first order of business, and be aware that you may still have a buildup in the line from the tank, so a second filter change may be in your future. Hopefully you have an inline filter that caught most, if not all of it. Ken and I were typing at the same time, but I'm more wordy!īased on my past I'd say that it's a pretty good bet that you sucked out a bunch of sediment out of the bottom of your gas tank when you ran out of gas. (having not done the rebuild myself, I naturally don't trust the work)Īny novice-level advice for (only owned this car 2 yrs, driven it 1) putting this miniature Exxon-Valdez back together smoothly? Add that onto I'm not sure if the vacuum system had/still has leak or if the engine is even firing 100% right. I've never tuned a card before, nevermind a tricarb setup. However I'm afraid of how smoothly everything will go when I try to put everything back together. THE PRESENT: I'm rebuildling all the carbs now (just a simple disassembly/carb soak/toothbrushing/new gaskets). I got her back a couple months ago but she still idles super rough. She was already leaking from everywhere and needed a rebuild anyway. I suspect I created a vacuum problems or blew out a gasket or something. She idled super rough but I was able to drive her home. After buying some gas (and a gas can) and filling her back up, when I finally got her started, I had a huge backfire out the center carb. THE PREAMBLE: Awhile back, I pushed my luck with how far I could go on a tank of gas, and ended up dry and unable to start. This requires a bit of a preamble, however. 312 Y block with 3x2bbl carbs (Ford/Holley 2100). I have a 57 Thunderbird that I can't get to run smoothly.
