Dnepr MT-11 Carb Float


Recommended Posts

Got fed up with the floats on the k63's on my dnepr.Put Walboro 82-85-7 float needles into it.

Wowser! Best thing one can do for the poor old thing..

I cleaned meticulusly, including the low speed needles [which I set to the same 1 1/2 turns] set the main needle's to the same height [had to locktite one, as it seemed loose], ensured that the floats were the same height, [see pic.] then checked both were at the same idle stop. I used 30 thou. at the engine side of the venturi for this, as I had the carbs completely off. After install I checked and adjusted the synch. [rather carelessly, using my finger]. Test ride, New machine!

Here is a pic of the new [with neoprene end] float needle, next to old one. And the angle of the float "arm" for the new float needle. In case someone else wants to see the angle I required. My camera don't do Macro, but if needed, I can get my boy to get a better shot.post-25511-0-69316200-1336065081_thumb.jpg

Now Me and my Monkey are off to the local Pub, for lunch and celebration!!

Later, and I hope this helps someone!!

It is the Kohler needle. The Carb. is in fact a Walboro, as far as I can tell. Cheaper cause I got it from the Walboro distributor.

I agree on the "what fits what" thread! Took me some time to chase this one down!! :feelssogood:

I got two of those float needles from my local small engine shop that had them in stock. One of them worked fine in one k65 but still had problems with the other one. After looking at the area where the needle seats I noted it's just a sharp square corner. The needles should sit in a 35 degree 'V' to seal properly. I had an old 3" long 1/4-20 bolt in a bucket with other hardware so I cut the 7/16 hex head off it, chucked it in my lathe, set the compound to 35 degrees, and cut a smooth 35 degree point on it. Then I measured the inside of the 'tube' the needles sit in and turned the bolt down just a tiny bit smaller. I then dropped the sharp end of my tool into the needle tube and taped it with a very small hammer. This imparted a nice 35 degree V where the walboro needles seat to stop fuel flow. This fixed both of my K65 carburetors! I was going to replace them but now there is no need. They perform far better than the original needles and both now are actually 'good' carburetors!
