Watts Engine Help

Merv C

Registered
A friend has a Watts engine S/n 173, about 4hp, 5 1/2' bore.
It would appear to be a hot bulb and we also believe it be rare. We know of two others but haven't seen them, one of them we do know is very different and is magneto ignition.
The one here is missing some of the governor parts, but we don't see that as a problem as we can copy a National governing system which is almost identical. The air intake valve appears to be an atmospheric valve.
We have the original fuel tank and that fits in a recess in the base, There appears to be no provision for a fuel pump and we think there should be a mixer of some sort opposite the fuel valve. The fuel must be sucked up from the tank.
We would be grateful for any help that would enable to get this engine running.
We will take photos and post them as soon as we can.
Merv.

Hi Merv, I have a similar engine to what you describe. I would be happy to share photos and information. Patrick the hot bulb (green engine) from the Rally, might you have a picture of it from of the opposite side?? Or anyone else who was at the Rally may have a photo of the other side of that engine?? I would really like to see it.

Merv there is a restored Watts some where in New Zealand. I have a copy of an English Stationary Engine Mag with a write up about it. I will try and hunt id down for you also.

regards Russell

G'day Russell'
Thanks for the reply, The one we have here is similar to the green hot bulb. I may be able to get some photos to morrow, Patrick's photo does confirm what we thought about the governor, so the missing parts can be made.
It also tells us there may not be a fuel pump and it looks like the fuel tank is in the base. Our one goes in a slot in the base under the cylinder. I think the only problem we have is, is with the fuel mixer, we don't have one, I think it is meant to push in the orifice and held with a set screw, it does have a threaded hole underneath. I think the orifice has later been threaded and a modern plug put in which has been drilled and threaded to to take an 1/8' fitting. Patrick's photo does indicates a mixer of some sort.
I can't see the air intake valve. Is it an atmospheric valve?
The two we know about, I believe are both runners and I know who has the mag ignition one. The other one, we don't know any thing about, but I know who did a lot of the engineering work on it. The owner has passed on and I don't know where it went, I didn't know the owner but we will try to find out. I don't think it is the one you refer to in NZ.
Another puzzle we have is, we have an ad for one which is the same as the one in Patrick knight's book "A to Z of British Stationary Engines"and that ad says" no lamp required" but is for a 7hp engine, but there are some differences, it is a hot bulb. I have scanned it but can't get it on photobucket to post it here.
At the moment we need detail of the fuel mixer and hot bulb cover.
The photos indicate both types of engine may use the same mixer. If so could they be the same as the National?

g'day merv
here are a few pics of my watts engine, my engine has a 5 inch bore. for the fuel system they have a special type of check valve on the tank with 2 balls fitted i gues as a back up it has the second ball, will get a pic of mine shortly, as for the fuel mixer, there is no mixer as such just a right angle fitting that screws into the hot bowl with a mixture screw in it. it also has a tube and a brass tap to control the amount of air going into the hot bowl as can be seen in the pics of my engine. i dont have the little right angle piece with the mixture screw but i have seen the green engine close up many a time and thats how the setup works. i dont have access to the green engine anymore as the owner passed away and his daughter inherited it and it has since gone form the district.
cheers

Merv my engine is very close to the same as Micks Hopefully these pics help you some what. I have just found my SEM issue with the Watts article. It is issue number330 sept2001 page 22 and 23. The chap who owned the engine is/was a Ted Parr of South Canterbury NZ. The photo's show an air silencer (quite small) attached to the air valve on the opposite side to the sideshaft. The pic showing the engine in it's as found state does look like thats the right spot. Question is is it actually an exhaust silencer or an air silencer?? Anyone who may know please yell out. have more pics if you want them
regards Russell

ok I seem to be having uploading problems so this link will show my Watts on webshots http://entertainment.webshots.com/album/579798561YJXEbt

g'day russell
yes it is an air silencer as your engine has one as well, national gas engines had a similar style of air silencer on them as it was supplied if the engine was to be in a building where noise is an issue, its a rare accessory for a national and would be even rarer for a watts!

Merv you might well know this guy, after reading the article again I see the owner retired and moved to Timaru!! mate it's in your back yard somewhere.It also mentions the engine being on loan to the Fairlie Museum.

Russell, that was the guy. He came to see me with his engineer before the restoration was started They didn't know what they had and I haven't seen them since , That's why I didn't know any thing about that engine and I couldn't remember his name. We had heard that it was in a museum. We will check out the Fairlie Museum.
I wasn't aware that it was featured in the SEM.
Last night I talked to the owner of the other one. He knew of two more the same as his, they are converted gas engines with magneto ignition. That is now five Watt's here (getting common).
Steve the owner has just registered here and he would like to contact you and Mick for a few more details and thanks to you guys we will get this engine running. Steve is able to make all the missing parts.

Hi Russell and Mick. Sorry for not being in contact earlier as been very busy up in Christchurch trying to move my brother out of his earthquake damaged house which is now basically destroyed. It was exciting to see your photos come up as trying to find one the same over here is like hens teeth, Merv and I are the right track with the governor so won't be long before I'll have this made. I'll have to ask you two to measure the length of the fuel/air intake tube from the top of the elbow to the bottom of the pipe as I'm missing that with the fuel valve.Have noticed that Mick's engine casting of the name is horizontal and my one is oval like Russell's so one must be older than the other, My serial number is 173 which Merv can verify as we found it on the big end bearing and the pully and keys and in front of the air intake valve, so will be interesting to see what numbers you both have.I'm going to try to post some pictures but might have to get Merv to help as I'm new to this. Cheers Steve..

It is amazing how engines get around. Thirty years ago there wasn't a lot engine movement internationally. I would be interested to know more about that one.
