    Correct gasket type for Stewart Vacuum Tank

    in Technical

    Posted · Edited by ARUCKEY (see edit history)

    I am in the process of rebuilding the vacuum tank on my 1929 Nash. Realized I used the incorrect gasket and sealer on the first attempt to rebuild. I use non-hardening sealer and it sucked into the unit. not good). I first gasket I used reacted with the fuel, became soft and bits were pulled into the unit. ( 2nd

    not good ) So, back to square one! Can someone suggest proper gasket material. Cork, rubber, synthetic ? And is a sealer required. Dykes manual does not talk about gaskets.

    I looked at previous posts about the discussion on the extra fitting opening (vacuum). did not see an answer but I'm thinking it is for vacuum wipers. My unit has a built in vacuum leak approx. 1/16 inch in diameter.

    Spoke Wheel Identify

    in What is it?

    Posted

    Unknown wheel, need help to identify. Wheel is 6.00 x 18 with 5 hole mounting. Possibly Rolls Royce. There is one hole thru the center hub. Could have been for side mount attachment. Any help is appreciated.

    I was fortunate to see the start of the GR in Traverse City, Michigan this year. There was at least one Buick speedster and maybe a second. I have to go back to my photos. I have a '26 Nash that I am considering making into a Speedster. My biggest problem was trying to determine is what shape to make the rear half of the car. I really don't care to have the fuel tank sitting on top right behind the driver as seen in lots of Speedsters. After seeing your sketches I think I would like to create some type of smooth body rear half. I have always liked the "hooded" effect just behind the driver and passengers head. Do you have more recent photos of the work in progress? Where in Upstate N.Y. do you live?

    I have a 1929 Nash touring with a 5.23 axle ratio. Engine speed gets to red line at 45 mph. Would like to travel at highway speeds (55-60)Would like to add standalone overdrive in center of vehicle. This would require 2 open drive shafts . One at each end of overdrive. An article I read sometime n the past talked about a Volvo overdrive unit being used for that purpose.

    Can anyone enlighten me on the subject.

    Thanks

    The basic problem is the pressure of the electric fuel pump which you already know. The reason pressue is the problem is as follows. The gravity tank is about 12 inches higher that the carburetor. This give the carburetor about 1/2 psi of pressure on the needle and seat. When you apply 5-6 psi with an electric fuel pump the pressure on the needle seat over comes the float. The float leverage cannot keep the needle against the seat. This raises the fuel level in the bowl which in turn causes a too rich condition. No doubt the main feed nozzle drip fuel at idle when only the idle needle should be providing fuel. At higher engine speeds it's also too rich.

    The first step is to try and find a small fuel pressure regulator to reduce the fuel pressre going into the carburetor. Second, is you have to get a "good" fuel pressure gage. By that I mean not a zero to 50 psi gage. You need a zero to 5 or 10 psi max. The big gages are not accurate at low readings. Once you have a good gage you can adjust the regulator to the 1/2 or 1 psi range.

    Reducing the main jet or needle seat size will probably get you in trouble at higher engine speeds. A danger of running too lean and burns valves or pistons.

    Once you start making modification to the carburetor it usually results in other problems. You have to remember that the car ran well for thousands of miles when it had the correct fuel pressure. Even though it was from a gravity tank.

    That's my two cents worth.

    I don't own a Saxon. This is amazing, I am the "Al" who is going to meet you later this week to work with you on your Saxon. I was just doing a little background research on AACA. Did not realize you also used this Technical area.

    See you later.
