Parcell and Weed Vertical air cooled engine

[cheepo45]

This is the vertical air cooled version. The castings came from Little Locos. The kit and plans are excellent! It has been a 3 year project.
I still have to tidy up the wiring and do some more fine tuning - but it works!
Enjoy!

Here is the engine cleaned up and ready for the shows!
This was the most challenging of my engine builds to date.
it has a lot of very small parts (especially in the hit and miss mechanism).
A lot of fiddling and adjustments were needed to get it to run properly.
Now on to the next project!

That has to be one of the most interesting engines I have seen! Excellent job.

It's an interesting engine .
Congratulations !
Can you take some pictures ? I can't see it clearly in the video

Here are some pictures.

It's cool and more beautiful with pictures !
Thanks for taking the pictures.
If you don't mind.....can you explain what the part marked in the picture does? I watched the video several times but still don't know how it works

@cheepo45, GREAT JOB on the build!

@minh-thanh, That's the inertia governor arm. It latches with a catch on the exhaust rocker to hold the exhaust valve open for the idle strokes. For the horizontal version of the engine, gravity helps to hold the arm down as a roller descends into a divot in the exhaust pushrod. For the vertical, a small spring at the base of the arm holds it against the rest of the governor parts. The vertical is more difficult to set up as two springs need to be balanced for the governor to work properly. If you replay the video in slow motion, you can see the engine latching in and out for the hit and miss strokes.

See the attached drawing for a better description as to how it works.
Enjoy,
Todd.

Very nice Scott...
I'm still trying to get the shop together since I moved. Maybe this winter I can get back into it....

 

[cheepo45]

Thanks, everyone.
This has been an interesting project.
I'm glad I got it completed before boating and fishing season!

Hi @cheepo45 , @littlelocos !
I forgot to say one thing,
When I search your website by your name, I understand why....

WOW ! Excellent build cheapo45 and excellent kit (and more) from Little Locos.
The video is great and the engine has a bizarre sound with the hit and miss cycle. The drop cloth background in the video and for the detail pictures is helpful. (My workbench looks like yours, he he, but who cares?)

I have always more-or-less glanced over the hit and miss engines because I didn't really understand them and never wanted to take the time to learn. This helps a lot, but I still don't really understand them......maybe eventually.
