Any Dnepr gurus in Denver Metro Area?

did you try replacing the seal between carb and head?

did you try replacing the seal between carb and head?

 

thanks, but not yet...if I understand things correctly, a problem with the seal here would be too much air, not too much fuel?

 

it's something that needs to be done of course, once we get past the fuel issue.

No fan of the K68s.

 

Get a set of K65Ts.

Set needle in middle position.

Install the small engine float needles.

Locktite the main jet post per http://www.russianir...k6365_carbs.htm

Done. Likely for many many years.

 

Thanks, the rig did come with K65 carburetors but one was leaking quite badly, which is why the owner went to K68 carbs.

The K65s are correct for the 650 Dnepr.

K68s were never factory installed.

K65Ts have 165 jets

K68Us have 190 jets

 

The leaking issue is the o-ring on the float needle. Probably eroded from using ethanol fuel.

Eventually the K68 will do the same.

 

Your owner sounds like they are a bit stubborn.

Best o luck.
