1927 Whippet Overland Carburetor

[76cat]

Good Morning,

 

I am new to your forum. I volunteer at the Corporate Office of the Saskatchewan Western Development Museum.  We are currently assessing a 1927 Whippet Overland to determine if it can reasonably be made into an operating vehicle.  it was restores some 30 years ago and was running at that time. It had an after market Tillotson updraft carburetor on it that was badly worn the original carburetor was apparently destroyed in an engine fire. Our research seems to indicate that it should have Tillotson S-4B but we are having trouble finding one. Will a Carter BB1 work??

 

Thanks for any help

The Whippet 4 in 1927 did use a Tillotson type S-4B carburetor.

 

The S-4B was zinc alloy, and cracked into many pieces, in some cases, so many they were called dust. It may have been the cause of the engine fire.

 

I doubt seriously if there is a useable original S-4B left in our solar system.

 

Carter listed the BB-1 number 245s as being a replacement for the 1928~1930 Whippet, but there was no listing for the 1927.

 

Checking Tillotson data, the 1928 used a type S-4C.

 

Further checking, the type S-4B and S-4C have different throttle levers.

 

If I were you, and had a BB-1 245s, I would be found trying to get it to fit.

Thank you so much Jon! We volunteer on Thursdays and I will take you very informative comments. Clearly our search for an S-4B is not going to be successful.

 

Take Care

Check out the Willys Overland Knight Registry (https://www.wokr.org/) .  I believe there is a Zenith carb that will fit the '27 whippet.  I still have the Tillotson S-4B on mine but may upgrade in the future to avoid the inevitable failure of the Tillotson.

I've got one kicking around. Send me a message! Located in Calgary.

There was an Australian brass copy of the Tillotson S4 sold as a Koala or Alpha brand carburettor. My Zebra had one fitted when I bought it. They seem pretty common over here so it might be worth checking ebay.

Hi Rob,

 

Thanks so much for your reply and great photo. As you have probably read I volunteer with the Saskatchewan Western Development Museum. My group at Corporate Office is currently restoring a 1929 Model A Roadster. This vehicle is classed as a running asset and when completed it will be used in parades etc.  While waiting for parts for the Model A, the museum has asked us to do an assessment on the 1927 Overland Whippet. It is an interesting change of pace.

The Whippet was restored many years ago and is also classed as a running asset. The body and interior are in great shape, except for a few scratches. Mechanically we are going through it to determine what needs to be done to get it running. Our group does not currently have a budget specifically for this vehicle and it may end up at the Moose Jaw Branch for completion depending on our assessment. The ignition switch had been bypassed as they had lost the key! We removed the switch and had a locksmith rekey it, we bench tested the switch and reinstalled it yesterday. The starter was not working well but fortunately we had a spare engine with a starter and we are hoping that will solve the problem, if not we have a local shop that does starters and generators for us. We have cleaned and serviced the vacuum fuel pump including installing fittings so it can be filled to facilitate starting. The next issue is the carburetor. It had a replacement Tillison on it as our records indicate the original was destroyed in a fire. From all the comments I have received that may have been quite normal. 

Our museum liaison is going to Moose Jaw this weekend for other steam projects and is going to pull the carburetor from the vehicle they wish to exchange for the one we are assessing. We are hoping this one can be rebuilt so we can get it started to complete our assessment. One of the items on our assessment will be that if they are going to drive it they will need to source a reliable carburetor. Your comments in this regard were greatly appreciated.

Sorry for rambling on, enjoy your golfing.
