Hey, so I got my r69s to idol for a few seconds. But hasn't really run for more than that yet. What are all the correct settings for the carbs? Also need carb rebuild kits x2 anyone know where I should go? My right hand carb needs a new slide needle, and the pin that goes through the float. Where can I get that stuff for not rediculous prices?

Duane Ausherman has the pages

Duane Ausherman has the pages of specs for the Bing carbs here:

http://w6rec.com/bing-carb-specs/

As for parts, there are generally two sources. Bing sells everything you need:

Or you can try a dealer. I've heard that some parts are cheaper at BMW dealers. You will need the numbers stamped into the body of the carb.

Update: got it running, but one carb doesn't get any fuel, any ideas? I think petcock, but I tried cleaning it.

Usually, the one petcock

Usually, the one petcock splits just below the tank to separate lines to the carbs. Somethings wrong with the splitter or the lines going to the carb. Pull the lines off of the inlet to the carbs. Open the petcock and catch the gas that comes out. Does the gas flow equally or not? If not, then work your way up.

The left side gets barely any

The left side gets barely any gas, I took it apart and cleaned it, the main inlet seems clogged, but the reserve seems alright. Did I reassemble it wrong? I put inline fuel filters in it, just till I get a tank or two through it. Any ideas?

So What Are You Saying?

So are you saying that the left fuel hose flows little or no fuel when pulled from the carburetor? Or the left carb seems to flow little fuel to the engine? Big difference. If a fuel line or petcock is plugged, that should be a 5 minute fix. If the carb jets are still plugged, then that needs addressed again. Sorry if I'm not understanding just what you think the problem is.

MAY I SUGGEST JUST DOING IT

Aloha,

It doesn't take much time to empty the tank, remove remove the petcock, the carbs, disassemble, clean, reassemble, and replace the hoses and gaskets. Doing this will identify future issues as well since there could be solids in the tank that are just going to sabotage the piecemeal work here.

A complete gasket kit for the carbs and petcock are <$20.00. If I remember, I did it for $11.00.

Hope this helps.

John

The petcock doesn't flow

The petcock doesn't flow enough fuel to the left side.

Is it the petcock? Did you

Is it the petcock? Did you remove the hose from the outlets for the petcock? If it's the petcock, then it has to be removed and serviced. Depending on the type of petcock, they can be disassembled and serviced.

I agree with johnpst

Even if it is the petcock I agree with John that you need to flush the whole system including the tank or you may find yourself back in the same spot again.
