Picture share of my carb fuel set jig inspired by nosmo and others!
- Thread starter Mercer
- Start date
Split collar was made and glued on one side and hose clamped on carb side.
Needed to make strut brace to allow for tuning to 0 degrees as some of my scrap tubing was too thin a schedule and flexed under weight of carbs.
Probably would not be necessary with heaviest schedule of tubing.
Thanks again nosmo!

pics #021 and 008 reveal second position of tool with carbs tilted at 20 degrees to set floats to 18 mm measure per Steve from SF..........
This position allows float needle pin to just be contacted by float metal adjustment tab but not be compressed or loaded.
CARB. jpg for example reference. Not a C10 carb.
Hope this detail of pics helps someone. Nosmo's pictures are no longer onsite though he was gracious enough to send me some in conversation.

Ok I have to post what most of us are probably thinking.
By the looks of your pix, you either live alone or the misses was away when you took the pix of your setup on the dining room table, especially without a towel or cardboard protecting the table, lol. Even with the table protected I would of probably got the "WHAT THE HE\\ IS THAT THING DOING ON MY TABLE", notce the comment are all in caps.
Thanks for posting your jig setup.

HaHa! It is a wood grain felt padded table protector about 1/4 inch thick. I had a white painters tarp in place but it did not have any contrast for the white pipe. My wife would surely object otherwise.
I am more blessed than one might think however as she has suggested I bring this C10 into our den that we do not use save for potted plants. This to reassemble there as the temps are getting high for outdoor work.
Am angling for an airconditioned work space in the shop. So thinking I will hold out and suffer a little more to that end. He He!
Nomos sent these pics after I used his parts list to fabricate mine....... his is more elegant and practical dare say!
Like like a C3PO to a RD2!
The real reason posting these however is his design is cleaner underneath!
Mine is too cluttered making use of allen wrench and screwdriver on bowls slightly difficult.
Would say his use of height and backward slant are design elements worth copying for ease of access.!
Just a thought post use of mine.
Also 20 degree slant inverted does not compress float needle pins inappropriately,
But could be less of angle to do same. In retrospect would back off to maybe 15 degrees instead.
OF NOTE ALSO: All my floats were set to 18MM and I still had one that read 1mm high no matter what I did bending float tab.
Needle spring issue I guess. It did feel different than other three. That is why you set to 18 then check fuel level after would suppose. Dual procedure but one tells more in the end.
Hope all that helps someone someday.

Thanks for the kind words. I tried to sell the design to NASA, but it turns out they don't use carburetors. Who'd thought? Maybe we should just switch to solid rocket boosters............
One thing I found out by being scrupulous about setting the FUEL level as opposed to just the float height.....The first time I went through my carbs I used after market float needles and the spring rates were not consistent. This allowed the actual fuel levels to vary a lot from one carb to another even though the float levels were the same. I solved the problem by getting Jen-you-whine Keihin needles from Murph.
Here's pic showing the how my setup will tilt any direction.
My fiance doesn't even like it when I eat at the dining room table, she'd prefer I eat and sleep out in the garage.

Yep, I went with maw kaw needles after having a # 4 stick. But needle springs seem to not like alcohol in gas do think. Now that I use fuel treatments and TW3 oil mix to tank fills problems like that are nil.
Am going to weigh #4 float just to be sure however. 8 grams do believe. Yeah am scrupulous as well on all carbs set exactly same. Wish I had a budget for a EGT probe set up like those NASA guys! Can not have a enough high tech tools!
Nice!
I made one to set the float levels on my CL77 carbs. Float adjustments on those carbs are pretty finicky and the ancient manual(s) leave room for interpretation. I got tired of repeatedly pulling the carbs to check and re-adjust them. Finally, just made the jig you see to hold them at the same angle they are when on the bike. Set the float tab to the correct (?) height, add fuel with a head of pressure, and jostle the sucker around. If no over-flow, it was good.

Being an old aircraft mechanic I've always wanted to put a 4-cylinder EGT system on my Connie, but yeah it's a little spendy. The big downside is it will never read what you expect it to and you'll spend the rest of your life ****ing around with your engine trying to "fix" something that isn't wrong. I've had airplane owners get really really mad because all of the cylinders on their engines aren't within 2 degrees of each other. Well......they aren't and won't ever be.

Ha! My wife wants all her tires like that! She thinks they put that feature on the dash so one would know and fix it. Except her idea of "fix it" is to park the car in front of shop and tell me as she walks in from her work commute.Being an old aircraft mechanic I've always wanted to put a 4-cylinder EGT system on my Connie, but yeah it's a little spendy.

We are at an age now where tech enslaves us to all these little screens.
As well she and I discuss this same subject post each commute as to why air pressure fluctuates.
I have not found a way to delete this feature from her dash and my life yet.
For those who would think it................... let alone say it..................divorce is not an option!
I might not find one ever again that buys me motorcycles for Christmas.................HA again!

Oh unrelated perhaps, I get my fuel line from Aircraft Spruce.

Careful with that Tygon fuel line . That stuff gets real flimsy when it heats up and can kink if the routing under the tank is not just right . Have seen many posts about starvation issues from that through the years...myself included .
