DCOE Redline linkage interferes - grind off the boss?

[sam1904]

Hi all.

I am installing my Redline linkage with my new DCOE's and have a contact issue with what appears to be an unused boss on the carb. 

If you see the picture below even after changing to a flat lever warm on the carb there is no room for a bolt head that will not hit the cast boss shown with the threaded hole in it. 

As this boss is unused I was considering cutting it off - am I missing something as I really don't want to hack into new carbs!

Thanks

Sam

Or (shameless self-promotion alert!),  just ditch the generic Redline stuff and get the best side draft linkage made for the 2002s!

I was looking at this this afternoon and wishing I had. One issue is I have this week off to get this done and then will struggle to find time for months. Do you have one in stock you could overnight tomorrow?

Feel fo to PM!

Yes we do.  I'll PM for details.

If you are going to work with what you have for the time being, yes you can grind it off.  Here's a close up of a setup I put together a couple years ago where you can see the ground boss.

I say just loose the nut between the arm and the heim joint and replace it with a washer, you can just use 2 wrenches to tighten it up. Then when Halboyles linkage arrives you can take your time installing it.

If you grind that idle stop boss off, you may need it later.

I would suggest trying to find a thinner nut or maybe a carriage bolt so you don't have to modify the carburetor.

[sam1904]

Thanks all. I decided to go with a new linkage from halboyles. Didn’t want to grind the boss off, wanted to avoid idle sync issues. 
As an FYI even a carriage bolt would not have worked, around 1mm clearance!

[AceAndrew]

Have yet to come across a setup that necessitated the second boss.... maybe in another decade or two or three.  THEN I'll come back and have my grandchildren write in that Toby was right.

I would just use the washer as one fellow suggested between the linkage and heim joint, a this jam nut to hold it together and if all else fails, just put a small bend in the linkage piece so it clears     The rods are adjustable so you can adjust as needed    it's not that complicated

Just give the arm a slight tweak to the right. That's how both of my arms are.

Thanks, I am going to actually use a different linkage but that would have been an option if not. With such a short radius I was a little worried about shortening it too much but as noted above 'its not that complicated -  just a 4-bar linkage trying to turn a rod!!

As above, I'd tweak the arm and switch the hardware around to put bolt head there or do the washer. I had to bend the arms to get the mechanical connection between carbs to mesh. I'd be reluctant to grind.
