Dwight Romberger Posted September 3, 2009 Share Posted September 3, 2009 When my Model 47 engine is cold, I have to crank the starter 30 to 40 seconds before it will fire up. Once it has started, it will start up immediately for the rest of the day.Runs smooth, love the car. I want to fix this before I burn out the starter, the bendix or my ankle.I appreciate the help.Dwight Link to comment Share on other sites More sharing options...
Guest Straight eight Posted September 3, 2009 Share Posted September 3, 2009 Well, there are all kinds of causes for your problem.Most likely it is the stuff they call gasoline. It is so volitile now days, that it will evaporate if you look at it. So, if you put the car away hot, that is after driving a bit, the warmth on the carb will assist the volitile gasoline to evaporate. So when you go to start it, the cranking of the engine operates the fuel pump filling the carb, and allowing the engine to start.Cheap fix. Keep a small pump oil can handy, and when you want to start, remove the air cleaner, give her a couple squirts of gas from the oil can, PUT THE AIR CLEANER BACK ON, crank her over, and you are on your way.A little more expensive is to install an electric fuel pump by the gas tank, and wire in a push button, so when you want to start, you can press the button, and fill the carb with fuel.

Mark Shaw Posted September 4, 2009 Share Posted September 4, 2009 Full choke until it pops and resume cranking without choke.... Link to comment Share on other sites More sharing options...
DavidAU Posted September 5, 2009 Share Posted September 5, 2009 Have the fuel pump checked. The little one way valves in the pump may be faulty and are allowing the gas to run back to the tank when the engine is off. It then has to suck the gas back up to the carb before it will start.

Dwight Romberger Posted September 5, 2009 Author Share Posted September 5, 2009 Thanks, David for the fuel pump info. I thought it might have something to do with pumping the gas up from the tank, but I didn't know about the one way valve. It makes sense.I think I'll pull the line off the carb, and see if there is a delay for the gas to arrive when I first crank.Thanks,Dwight Link to comment Share on other sites More sharing options...
Dwight Romberger Posted September 5, 2009 Author Share Posted September 5, 2009 Mark,I do crank with the choke all the way open, and it seems like when the gas arrives at the carb, it fires right up.Thanks,Dwight Link to comment Share on other sites More sharing options...
Fred Rawling Posted September 7, 2009 Share Posted September 7, 2009 How old is the diaphram in your fuel pump? If it is old, the new gasoline may have weekened it so it is not as efficient. Also, the valves in the pump come with the rebuild kit.My answer was going to be the same as Mark's. Choke it till it fires and then push the choke almost all the way in until it warms up.
