Hi all;
A few days of no work this week resulted in some serious shop time, spent making carburetor parts.
Finished all but two clamps that hold the fuel needle assemblies into the body.
Test fitting of governor and throttle linkage, I chucked up the crankshaft between the three jaw and live...
A little more done on the carb. this week.
Made a mandrel to turn the 1/2" throttle valve (butterfly) 80 degrees to the axis of the mandrel.
This gave the plate a 10 degree angle on the edge and the proper oval shape.
Also did the throttle shaft and arm.
Small parts sure do take up a lot of...
Hi;
Thanks everyone for the kind comments, I am happy with how it runs now
but it took awhile to get there.
Andrew, I am heading back out right now to continue on the Fairbanks. :)

Hi George;
Beautiful work on the ignitor. The ingnitor for the 1/5 scale Famous uses a .375'' body
and a flange for mounting, it works well.
Hope you can have it ready for Names.

Hi Andrew;
Thanks for posting that, quite interesting. Now I have an idea of what you do.
;D It looks like you might have enough equipment there to make small engine parts! :big:
Hi;
A couple pictures of this weeks progress on the carb.
Boring the filler hole in the starting fuel tank and
the carburetor at home on the engine.
A couple dozen more little parts and it will be a carburetor.

Hi;
Spent the weekend working on the carburetor, a lot more time into the fixture than the casting.
Went well, everything is dead on.
The shims ended up in the fixture because apparently I cannot differentiate between .003'' & .030''

Thanks Chuck, now I am really keen to try it,I have an idea for a belted machine to bring the engine to operating temp. I love the smell of an engine running on kerosene, noisy, inefficient, and stinky, love it.

Hi Chuck;
Thanks for looking.
Bore and stroke 1 1/2" x 2"
Flywheel diameter is 8"
I started laying out the carburetor casting today, it is a two fuel carb. modeled after the real deal.
I am looking forward to seeing if I really can run a model engine on kerosene.

Hi Andrew;
I think maybe a little more than a week, maybe two :big:
I am trying to incorporate the shaper into my work. I had all three machines running at the same time
when I was doing the bearing caps, very productive ;D.
