[Fuel boiling at shutoff in Stromberg 2brl]

This isn't happening to anyone? Just me?

[Fuel boiling at shutoff in Stromberg 2brl]

Thanks Jim, I tried the thicker gasket approach to no avail. I was in the process of building a heat shield out of aluminum sheet stock (there are no available 2 brl. kits) when the electric fuel pump was suggested.<P> As far as bowl ventilation goes, I went through 3 carbs each one rebuilt at least twice, including 2 different professional rebuilds. (Have you ever tried to find a Stromberg WW2/112A {1959} or 113 {1960}? I've been shopping the whole of Hershey and Carlisle for 5 years and I'll bet I've only seen 6, and about 5 kits! Most of those I bought, along w/ 3 or 4 others at smaller meets. There was just an NOS WW2/113 on Ebay last month that went for $350 [bidding started @ $20]).<P> I don't believe there is provision for adequate bowl ventilation in my carb. When this was happening, gas would be seeping slowly out the vent (as liquid), and through every gasket surface on the carb, all at apparantly equal rates. The combined effect was enough to have gas dripping off the throttle linkage @ a rate of about 2-5 drops per second for about 10' until the bowl and fuel line were dry. Even an new, custom made Viton needle and seat on the inlet didn't help.<P> As far as the heat riser is concerned, its free and appears to be operating fine. When I first got the car it had ben running for some time with leaking valve cover and intake gaskets, with leaked oil being sucked in through the gasket forming a solid carbon mass in the exhaust passage there. I sandblasted the passage back open, but it had no effect on the gas leakage situation. Also the fuel would boil only at shutoff, never while the car ran. In 11K miles I've never once had a vapor lock problem or noticed gas fumes while driving. You'd better believe there were fumes at shutoff, however.<P> As you can see I'm at a complete loss here. I've only seen one other 1959/60 Stromberg 2 brl., it at the 1999 Buick National @ Columbus OH, and it didn't seem to have this problem. The combination is extremely rare, the Stromberg by 1960 was relegated only to low compression engines which were only installed on manual tranny cars or on automatic cars where low compression was optioned ($54, more that duals!). Based on the amount of spare parts for this combo I've seen vs. the Rochester 2 brl., I'd say less than 1% of 1960 Buicks came w/ Strombergs. I'm not able to come by advice for this car very easily. <P>p.s. Another weird thing, the car runs great, I got 17 mpg on the trip to Columbus! However, I'm carbon fouling plugs badly. At 800-1000 miles they are so fouled the cars starts to misfire. I can't lean it out any more than is is w/o having it stumble @ idle. I was told it could be valve guides, but there's no blue (or black) smoke in the exhaust, not even a slight hint at startup.<BR>Changing carbs didn't fix this either. Could it be related to the fuel problem?

[Boiling fuel in 1960 Buick Stromberg 2 brl]

Please see my posting on this subject in the BCA performance forum for background on my problem. I fixed my 1960 LeSabre's habit of boiling dry the carb and fuel line at shutoff with an electric fuel pump. Are there any alternatives?

Please see my reply to AOrnest@AOL.com's posting on "65 carter AFB problems" for a more detailed explanation of the problem. A short version is as follows. I was having major fuel leakage out of the carberator in a 1960 LeSabre w/ a Stromberg 2 barrel (WW2 model) at shutoff. Gas would run down the carb throat and seep through the body, dripping at a rapid rate off of the linkage. It was explained to me that the fuel was boiling in the carb due to today's gas having a very low boiling point. The WW2 carb is VERY small for a big block V8, and that made it worse. I fixed the problem with an electric fuel pump and by locating the fuel line away from the engine. I did not see any other cars having this problem, however, at the 1999 BCA National. AM I ALONE???? Is this something really unique to my car or are other people seeing this? I did not change the fuel pump, and did notice gas in the oil (now fixed). However the gas was definately running down the carb throat at a rapid rate after shutoff and I blamed that for the gas in the oil. Could the fuel pump cause this? I must note that as long as the motor was running no gas leaked and none seemed to reach the oil either (long trips did not flood the crankcase).
