1941 deluxe six possible carburator problems Need Help

BernieBuechman

My Hudson ran fine 3 days ago parked it and the today went to start it it ran for about 5 seconds like on 3 cylinders and then after trying to get it started for some 15 mins gas came up and out of the float chamber area from a tiny hole. someone told me he had this problem and it was a matter of setting the timing at the distributor. anyone had this problem and is it a firing problem or carburetor one. I am hoping to ride my car this year and need all your advice possible here. I will check the plugs for fire tomorrow and go from there but Would like to here your ideas on a possible problem.

                                                                                                                               Thanks Bernie

If gas is coming out of the float chamber, could it be a simple problem of a stuck needle valve causing fuel to gush into the chamber?  Have you tried lightly tapping the top of the carburetor with a small hammer or other object, to un-stick the valve?

I have to agree with Jon B on this one. Cant see what would have knocked it out of time just sitting overnight. But stranger things....   Keep us posted

Thanks everyone it seems a Hudson guy in Bancroft gave me some advice as well. I grew up on the old cars well for me 60's and up but the tapping on the float chamber and a stuck float needle valve. I tried carburator cleaner today and it seems my float chamber lid or cover has 2 tiny holes in it one has a copper line into it for the heater in the car the other hole not sure of So I put a small piece of wire into the chamber and pushed on the float. the engine started later with many words not to repeat here and so far I only have a leaking fuel strainer gasket. Now all this said I had a oil change done some 20 miles ago and it seems my oil is as dirty now as when I had it changed. Except today I took out the dip stick and it smells of gas and oil. It will be a premature but needed oil change tomorrow. I had marvels mystery oil in it for the last oil change it seems this cleans out the engine of carbon etc. is this why my oil was so black so soon. anyway if the car starts tomorrow I will let it run a little and then drain the oil. I had my wife look into the carb while it was turning over and pumping the pedal the good news is her hair is all good and she seen a spray of gas so the car has fire and gas  and my wife has her lovely spiked hair yet without a dark tanned face.

Just remember that when you drain the oil - there is a litre or 2 remaining in the buckets above the oil pan which will merge with the new oil and dirty it cheers Ken

Bernie, if you have never dropped the oil pans to clean them, this would be a good time to do it.  The coupe I just bought out of 50 years of storage with 33K miles had the center main bearing out of it due to a plugged oil hole.

Jon B

I agree with the suggestion to drop the pan and make sure it's clean.

Also: the reason you may smell gasoline in the oil, is because of the excess gasoline that was going through the carburetor.  It would not have been burned so would have gone down past the piston rings and into the oil pan, to mix with the oil.

Thanks to all of you so when I did the oil change I took all of the old oil out of the filter canister and then I ran 5 liters of oil through the dipstick filler area and let drain then I 
filled my oil. after that I started the car which by the way has never stated so well since I owned it. the oil is not to bad looking at all. I shall remember the oil pan issue when I take the car in to have the pinion seal done. So Ken what is that about 2 buckets above the oil pan I am not understanding that could you please let me know more about that as I was not aware of that but I would like to know more.

                                                              Thanks so much Guys

There is a sub tray located above the main sump which contains the "buckets" Ken is referring to. The connecting rods have scoops that scoop oil out of these buckets as the engine rotates to lubricate the entire engine. When you drain the oil from the main sump as you have, the buckets retain the old oil. You may find it "dirties up" after a short amount of use as it flushes the old oil out of these buckets and it mixes with the new.

Jon B

Ken means the "dipper tray", I believe.  This is a separate tray that fits into the top of the oil pan, and into which the "dippers" on each of the connecting rods, scoop up oil to lubricate the rod bearings.  When you drop the oil pan, the dipper tray will come down with it.  When you replace the pan, you will of course place the dipper tray in the top of the pan, and you must fill it with enough new oil so that when the engine starts, the connecting rod dippers will have an immediate source of oil.  Otherwise, if you don't fill it, the con rod bearings will burn out in short order.

Ken is pointing out that -- when you do a standard oil change -- and remove the oil pan plug and drain the old oil -- the old oil will remain in the dipper tray.  (There is no way to drain it, unless you remove the entire oil pan with dipper tray.)  So, even though you replace the old oil with new oil, there will always remain a small amount of used, dirty oil in the dipper tray.

I have found the oil in my 41 is very dirty looking in a short time.  Even after having the pan and tray down for cleaning it did not take long.   No oil filter and remember back in the day oil changes were less miles and every 5000 miles Hudson advised to drop the pan and clean it.

Thanks to everyone I have learnt a lot I am Very Thankful.

Bernie, it's also a good idea to add fresh oil into the oil filter canister when you change the oil.  The oil in there should be in addition to whatever you put in the pan (ie 5L).

I would like to turn down the idle speed of my Hudson it has a wa1 carter carb, Where is the screw for doing this is it the screw which is on the throttle linkage facing towards the manifold where you can not get a screw driver in.

Have you seen this carburetor bulletin?  http://hudsonterraplane.com/tech/1935/1935-42HudsonCarbManual.pdf

BernieBuechman

Thanks Jon,

 I have seen the bulletin you really need to see the carb in 3d now I have found the screw but no room between the end of it for a screw driver because of the distance between the manifold and the head of the screw. what have others used to turn this screw pliers or a home made device.
