Carb rebuild new cables....

[Barry]

As I understand it, the butterfly valves can be fitted the wrong way round as the edges are not square. The resting position is not 90 Deg so the edges are  slightly angled to fit precisely in the bore.  

Is this a possibility ?

I noticed that and since I rebuilt only one at a time I had the other to copy from.

Judging by how small the mix hole is and how much effect it has on the operation of the carb it's real possible the butterfly could be the culprit.

cant wait to get home to try it!

But no pressure. Right, Ampy? Good luck, buddy.

Steady breathing, calm, ahmmmm...

I got home managed to pull my carbs off and pull all the idle set screw out so each throttle would bottom out all the way for an accurate measurement .

I have shone a light down the backside of each carb and DO see a difference.

Measuring as closely as possible with a digital caliper I find a difference of .039mm between the carbs.

This doesn't seem like a lot but as stated before tiny differences make a major difference in carbs.

It at least gives me hope that there is a previousely unnoticed difference.

I took pictures but they are not clear enough to see.

I didnt get to do any actual changes tonight because of a prior engagement but will do it first thing in the morning!

Thanks to all who have suggest possible solutions!!

The problem SEEMS to be gone completely and entirely!

It was the throttle plate alignment...I took both carbs off and did the flashlight test and a small amount of light was passing thru each butterfly but in different amounts.

When I pulled the throttle arm light came thru the top side first.

I loosened the 2 screws on each gave a quick jiggle on the thottle arm holding the carb upside down and it fell into a perfect seat so NO LIGHT AT ALL passed and as I pulled on the throttle arm the light came thru equally all the way around.

Reinstalled the carbs went for a warm up ride and instantly noticed an improvement.

Got back from a 10 miler already had my manometer, fan and tools ready to rock pulled in the garage went thru the proceedure (I've gotten really good at it lately) went out for another test ride and IT WAS PERFECT!!!!!! I can sit at a stop light for minutes without touching the throttle then roll it on smooth as you please!!!

Monte had the winning suggestion and for that I am truly thankful!!

And to show my sincere thanks I have decided to NAME ONE OF MY CHICKENS AFTER MONTE!!!

You said you loosened the screws on the throttle butterfly plates, after tightening the screws, they need to be 'peened over' on the back side to prevent them from vibrating loose .

Bob, I opted for the blue loctite per snowbums site....hopefully that will work.
I also lightly crimped the threads on the backside sticking out.

As long as you did something to the screws, as I don't think they would stay in place without Locktite, or peening .

Truthfully, Ampy, your last line caught me flat-footed. Nearly fell outta the chair laughing so hard. Had to show my wife... she didn't get it. Wonder why?

I'm honored. Post a pic of my namesake.  Ain't we havin' fun here at the R65 asylum?    Monte

You named one of your free range laying hens after Monte?  That is too cool! [smiley=ROTFLMAO.gif]

[montmil]

That thought did cross my mind. Perhaps Monica?  

[weasel01]

The official name is "Monte the Voodoo hen" I took pictures this morning and will post them tonight
