Need help with a PAW 19 diesel

[Tim Edmunds]

After a long absence my PAW 19 diesel has finally resufaced. Remarkably
after 21 years lost in my parents garage the engine still turns freely
and doesn't have any rust. I want to get it going again and have some
questions as the original instructions are still lost. This is the
control line version with the ring muffler.

The questions I have are; 1) what size prop to use? 2)what size plane
plane to put it in? I looked at the CL models for 19-20 size glow engines
and they seem substantially smaller that I used to fly 20 years ago. 3)
where can I get a carb if I want to convert it to RC?

Thanks

Tim,
The PAW 19 (19CI) is a 3.2cc engine that weighs 6 oz, has an RPM range of
4-17,000, and will
swing any prop from a 7/6 to a 10/6.

I plan on putting a .15 PAW in my Butterfly as soon as I get it built. I am
not sure exactly how
large of a plane it will handle, but the engine runs at less RPM, swings a
larger prop, and runs
about twice as long on the same amount of fuel. They do slobber out more
oil, but you get
hooked on the smell of diesel after a bit. The .19 should be approximately
the same as a .25-.29
Glow fuel engine.

You can contact the folks at PAW directly for parts and information.

Also, here in the US you may contact:

Mr. Ed Carlson at

You should send Mr. Ed Carlson one dollar and get his latest catalog. It
not only has a
very good selection of Diesel engines, but has some very good information on
how to
operate a diesel. Make sure you read his information carefully, and more
than once.
DON'T USE AN ELECTRIC STARTER, and I would suggest purchasing some
Diesel fuel until you are once again familiar with the PAW's operation.
Then you can
mix your own if you must.

He should also have an R/C carb for purchase, or can get you one. I don't
think you
will be able to get the older style R/C carbs anymore, but you will probably
want the
newest style since it is suppose to be better anyway. You may also want to
get an
extra GRUB screw or two with the R/C carb.

Just make sure you don't run it "OVERCOMPRESSED". That is a quick way to
kill
any diesel engine.

You can pick up Tygon hose just about anywhere for the fuel line.

If you want me to copy my original PAW paperwork and send you the copy,
drop me an e-mail with your address.

Let me know if I can be of further help.

Tim,

Start with a 10 X 4 or 9 x 6 prop.

Put it in any plane designed for a .20 like a SIG Seniorita.

PAW have an advanced carb, the Varijet, but only for .29 to .60 engines. The
advantage of the new carb is that it gives a lower idle and more linear
throttling. Primitive though it is, the older and simpler type of PAW carb
still works remarkably well. It may be a bit difficult to fit an R/c carb on
your engine as it was made before the two were made interchangeable. You will
have an integral venturi and probably the holes are not tapped out to fit an
R/C carb.

I will send you my diesel booklet seperately as an attachment

Hi Tim,

I just acquired a similar vintage PAW 19D from a friend, for all the answers
straight from the horses mouth, try PAW's website:
http://users.tinyonline.co.uk/wendy.eifflaender/

and if the answers aren't there, an E-mail to the address on the website
will get an answer from the engine's designer, usually within an hour or
two!

Happy dieseling!

Thanks to everyone who replied to this post. With luck I'll get the
engine going this weekend.
