Great to see your project running Gus. Now you have bragging rights. well done
 
Nice work! :) I has a Webster engine with water jacket and wick lubricator to both bearings and cylinder (less messy) and own made carburator with venturi inside. :)

Hi Big Bro. Goldflash and Guys,

Webbie is not very forgiving. The latitude band is so narrow.Over shoot into the grey area and red area,she won't start/run. However with carb tuned and all cam timing done, she started easily subsequently for three times. Webbie is a dirty engine with oil cup lubrication.:cool::cool:
Following need rework,
1. Just notice Outerhead Gasket leaks.
2. Jet valve needle too crude and carb not very responsive. Will make new needle.
3. Intake valve tappet n spring rework.
4. Recycled fuel hose not in good condition.
5. Cylinder lubricator n needle need rework to much oil going thru.

Will tidy up and dress up for fotos taking and crowing. Gus got his very first IC engine started and running.:cool::cool::cool:

Will post video when I succeed uploading on Youtube or PhotoBucket.
 
Gus..

2. Jet valve needle too crude and carb not very responsive. Will make new needle.

Use fine tread screw and a sharp needle for fine tuning of fuel/airmix. Grind the needle with a cutting disc on dremel when the needle is rotating on lathe.

The petrol/gasoline has high energy value than methanol and need much less petrol/gasoline mixed in air.

3. Intake valve tappet n spring rework.

Use a soft valve spring for improved idling if you need low revolution as a old boat engine such as pow-pow-pow... In hi reving Webster need a stiff valve spring.

5. Cylinder lubricator n needle need rework to much oil going thru.

Replace with a wick lubricator, it is less messy.

You can mount the adjuting air screw direct into the carburator intake with 2 hole in both sides (See my movie above) to regulate revolution.

Hi Cogsy,

Five minutes ago.
Plugged enough courage to take Webbie by the horn.
Take up the slag in the intake valve spring,fine adjust/tune fuel jet.
Webbie now start easily with power starter at first spin. Darling boss watching
evening soap opera order Gus to shut tdown the racket.Yes.Boss.

Video taken. Now figuring out how to put on YouTube and on to HMEM.
 
Hi Gus.
Cograts.
Like you say, the Webster is a messy bast...d with cuplubrication.:fan:I stoped using it. Insted I add some oil/W40 in the petrol .Just a small amount, works well.

Best reg.
CS

Hi Paul,

I did. Showed my darling boss the running video and she asked-------" What is this for? Makes too much noise.Can you make it run slower and quieter.

IC engines has always been my fear of the unknown. Will be following your new engine build.

Darling Boss just gone over to the church opposite for meeting. Will spin Webbie again!!!!
 
Good work Gus, congratulations. Your posts were always interesting to read and thanks for taking the time to post your progress.Thm:

I'm also working on my first IC engine but it will take me longer than 3 months I'm sure. I'm hoping for the same results that you've had

Cheers,
Phil

Gus --Congratulations. You are now a member of a very select club. You have created an engine from bar stock, an accomplishment to be very proud of. Think about it---Of all the people you have met, over a lifetime, how many of them are able to say they have done that. You should be very proud!!!---Brian
 
Looks great Gus. Can not wait for the video.
Also the fish looks very good.

I go away for a few days and return to find Webbie running and fixed up nicely. Congratulations Gus!

Jim
 
Gus,
Its great to hear the report that it is running, that in itself is an accomplishment. My experience with my own engine is that it evolves over time. Great job!

Hi Guru,

Thanks for the useful tips. Just replace intake valve spring for easy starting.
Had a spin 10 mins ago. Did get to low idling speed.
Have a long rework list. Later plan to try out OS carb just out of curiosity.
Will use wick type lubricator.

Hi Brian,

Thanks for the congrats and admission to the exclusive club of IC engine builders.
Nearly gave up.Threw in my hat and towel etc.

After Webbie,I will rework the "FireFly" glow plug aeromodel engine now on the computer shelf staring at me. See foto.

Webbie after running in, now has very good compression.Hand spin starting not possible with this high compression. The valves and piston rings did seat in and very well too.
