As I watched this video, I thought how in WWII Caterpillar built the dozers that constructed the runways that sent the planes that bombed Japan where years later a company called Makita built the drill that is being used to help restore the Caterpillar dozer. Irony. Things come full circle sometimes. Love the series.
This is great stuff Sr. Thanks for the info on that passage, I’m sure that will help lots of people. Any chance you can post a link to where you got the carb kit from?
I’m still amazed that this carb for a little 2 cylinder pony is more complicated than any small engine carb 80s and never that I’ve ever taken apart. Thanks for the video
It's really cool to keep things original. Please don't get me wrong. But for stuff I use regularly, I see no problem in upgrading to newer parts which just work. Carbs for example.
Out of several ways to control drill depth, take a wooden dowel such as 1/2” and drill down the center of it with the bit you plan to use. With the end of the drilled dowel now hitting the drill chuck cut it to length so the drill bit only has X amount exposed. X is the depth of the hole needed so the dowel limits it to prevent internal carb damage.
Very nice tutorial Senior. I sure wish you would do more tutorials on things like: chainsaw sharpening, replacing a axe handle or hammer handle, etc. You have a way with explaining things in a calm and thorough manner.
Nice job cleaning all those parts. I have had good luck cleaning carbs by spray blasting them with baking soda (powder). Cleans very well and dissolves completely in the final wash.
I dipped tap in grease when I was tapping deep in aluminum head to install sparkplug sleeve. It needs to be cleaned and regressed like every turn, but almost no chips ends up falling, they just stick to greese. I know, that in this case this method makes no difference, but it is still cool
Always good to learn how to do things more proficient them down draft carbs are not easy to work on. As for my d8 i dont know what broke the casting it froze or if some hit it but i brass welded it there was one on line they wanted 600 all painted and nice im like a new zenith is only 300 so i preped and brassed mine back together i put pics up on fb the price of the on i was looking at went to 1000 i like well mine is fixed it doesnt leak and pony runs great i have just a word for him that was tring to sell a carb for more then its worth i have studied welding my first book in welding was a 1939 addition of the James Fulton Lincoln weld book
When i get my slide show video up you will see my work and on an in frame over haul of a seized engine engine seized before it was left sit for 30 yrs there was prof in the dissasembly
Great info on what can be done. Seems odd the carb kits don’t come with those plugs, but I guess they are not considered serviceable items. What kind of symptoms do you get if the compensation passage is blocked? Rebuilding carb on mine as it floods easily when gas is turned on full. Have to adjust it just right once it is running. Pretty sure it is the float or the float shutoff valve. Have not had a chance yet to run it yet. Need to check the endplay on the crank, and check the main bearings, while I have the pony out. Just from the feel it seems like too much.
Hi thanks for the video it was really helpful for me. I did everything in the video including drilling and tapping the passages. However my pony motor does start and run but it still does not want to run without some choke on, I.e I cant turn the choke off completely. It also seems that my motor does not rev as high as ive seen others on video. Would you know if the magneto timing possibly needs to be advanced and how I might do that? When I engage the compression release on my D318 it just kills the pony motor. I am desparate for help.
I couldn't help but notice the lockdown handle on your columbian vise sticks out sideways in the way of your work area. You can try different thickness washers and get the handle to align straight with the vise. Gives it a clean look and also keeps the handle from getting in the way.
One thing I would do is if you using gasoline in those carburetors which most likely you are to use ethanol free gasoline 3 gasoline or also known as 0 ethanol gasoline
I'm assuming you use the same carb parts guy as I do,...I've got to find somewhere else to go now that he's retired so feel free to offer any suggestions other than Robert's LOL
Man you can learn a lot from Senior! He’s got a great technique and expertise on doing his stuff! Nicely done!

Fine example of experience on what most people consider a lost art,I love it.
Your one hell of a teacher
Enjoying the Senior content! It's been a while.
That old stuff is Just so much better built then anything in todays world..Love old Iron..Great Video Senior
This is great stuff Sr. Thanks for the info on that passage, I’m sure that will help lots of people. Any chance you can post a link to where you got the carb kit from?
@@squatch253 I’ve bought some stuff from him, excellent place to buy carb parts!!
Caterpillar carb kit 4M-8436
I’m still amazed that this carb for a little 2 cylinder pony is more complicated than any small engine carb 80s and never that I’ve ever taken apart. Thanks for the video
Thank you for the video.
Another great demo, Senior! I've done a couple of them for the JD R Diesel pony motors. Very cool little carburetors.
thank you sir for the info!
Wonderful video the screws are a good way to seal off the passages so you can clean them properly
@@squatch253 I can totally understand that the modern gas evaporates so easy now a days and leaves the rust behind
Like Senior so is Junior. I see where Junior gets the attention to details and mechanical skills!! Wonderful video and a joy to watch!!
I wish Sr could be involved with more videos. He has a wealth of knowledge that needs to be shared. Very good series. Thanks
I really like this new guy a lot better 🤣🤣🤣

squatch senior that is absolutely brilliant Using a 177 caliber pellet To put a plug in a passage of a carburetor I guess it goes use what you have
BB gun maybe? 😏
Are you going to do Maple sap this year? Should be runnin' soon.
Very nice tutorial Senior. I sure wish you would do more tutorials on things like: chainsaw sharpening, replacing a axe handle or hammer handle, etc. You have a way with explaining things in a calm and thorough manner.
This is a great tip to use in keeping these carbs. clean. Thanks very much for sharing your information here.
A man that knows how to use a file.
You can get short button head screws also. You can trim them before installing them as well.
Very good information 🌎🌞😊👍👍👍👍
Nice one Snr. I have never been brave enough to remove lead plugs.

Also notice how he modulates the speed of the drill hes not going in at full force gives him more control
Thank you sir

Jr will get a heart attack once he finds out you did not use genuine CAT parts by the book - even modifying your carburetor ! 😵
If you don’t mind me asking, what trade or profession were you in before you retired? Thanks!
I've used the cleaning bucket you use... I'm wondering what you do after the parts are clean,, do you use a rinse or compressed air?
One thing I would do is if you using gasoline in those carburetors which most likely you are to use ethanol free gasoline 3 gasoline or also known as 0 ethanol gasoline
👍👍👍 Thanks
I'm assuming you use the same carb parts guy as I do,...I've got to find somewhere else to go now that he's retired so feel free to offer any suggestions other than Robert's LOL
@@squatch253 he sold out and is retiring, last I talked him (November) he was planning on being out by April this year.
Now I know where Squatch got all his knowledge.
I guess the plug is in a casting passage and it's has side paasges.
heeeyyy grandpa squatch!
