414TATA Posted June 20, 2013 Share Posted June 20, 2013 Hey Buick loversI have a 248 C.I. with dual carbs. If this Buick doesn't start with the first slow down push on the accelerator it gets flooded. It will start on the next couple tries but I have to wait about 10 minutes between each, if the first try fails. I drive this car at least once a week about 20 miles. The temp in the garage is about 70 / 75 degrees F. Common? What can I do about it?ThanksWayne 1941 Super 51 Link to comment Share on other sites More sharing options...
FLYER15015 Posted June 20, 2013 Share Posted June 20, 2013 Wayne,You might want to consider a hidden push button starter switch.When you step on the gas pedal you are operating the accelerator plunger on the carb, and sending a big gulp of fuel down the carb throat.It ends up as a puddle in the bottom of the intake manifold and the next cylinder to open gets more than it can handle.Mike in Colorado Link to comment Share on other sites More sharing options...
danhar1960 Posted June 20, 2013 Share Posted June 20, 2013 Are they Carter or Stromberg ??Danny Link to comment Share on other sites More sharing options...
Guest Posted June 20, 2013 Share Posted June 20, 2013 When I had my 53 Special it used to flood in the Prairie winters. What I found worked was to depress the accelerator to the appropriate spot and then turn the key on and off and on again if it didn't start without moving the accelerator pedal. The idea of the starter being linked to the gas pedal was an excellent idea except in these flooding conditions. Link to comment Share on other sites More sharing options...

I did this on my 41 Century years ago and more recently on my 41 super Link to comment Share on other sites More sharing options...
jenz38 Posted June 20, 2013 Share Posted June 20, 2013 Me too have a Starter Switch under the Dash, in one of the original Holes on left Side of the Colloumn. 1. Because of the flooding and 2. the Danger while accelerating with a broken Vakuumswitch to damage my Starter and Flywheel. Link to comment Share on other sites More sharing options...

Looks like a starter switch will do it.Dannythey are Stromberg and were both rebuilt about 22 months ago. Link to comment Share on other sites More sharing options...
danhar1960 Posted June 28, 2013 Share Posted June 28, 2013 Oops, sorry Wayne, I did mean to get back to this.Just a thought:The pump piston stroke on Strombergs has 3 setting positions. It could be that the stroke is set to long and delivering too much fuel. Is the rod to the pump piston currently in the middle hole ??Danny Link to comment Share on other sites More sharing options...
414TATA Posted July 2, 2013 Author Share Posted July 2, 2013 Thanks DannyNo mechanic here. Any chance someone has a photo. Thought I could see what you are talking about but I really can't figure it out.:confused: Any photo of carb. set up will help.ThanksWayne Link to comment Share on other sites More sharing options...
Guest Grant Magrath Posted July 3, 2013 Share Posted July 3, 2013 The piston pokes out the top of the carb and has a rod running down from it. See the three holes at the bottom of the rod?CheersGrantPS this image won't hang around long. It's a listing on ebay. Link to comment Share on other sites More sharing options...
