038 Mag Tilly Carb with compensator
« on: May 01, 2017, 09:06:40 pm »
I have a feeling my Bing has failed me. Saw keeps flooding terribly. Replacing the carb was cheaper and quicker than rebuilding the Bing. However, this Tilly knockoff (didn't realize it was a fake when I ordered it) has the compensator plate. Now, I have a filter with what appears to be a receptacle for such a hose but when I install the carb and the filter it doesn't appear a hose could make that turn. Can anyone provide pictures or insight on how to make this work?

To install this replacement carburetor in a machine without a compensator connection on the air filter, remove the end cover with connecting elbow, and fit  in its place an end cover without connecting elbow.

There once was a time the rebuild kits for the OEM Bing were only available through Stihl and were rather costly .Oregon sells them now and a basic kit with just the soft components are moderately  priced .

Sometimes on the 038 Bing the metering lever height was too high/too low and you cannot bend or adjust the plastic lever. But the seat the inlet needle seats on is movable,very carefully with a flat punch you can tap the seat one way or other and get correct metering lever height.
They were a good carb and ran well.

Mike, I remember my 1st year 038 Magnum I bought in 1985 had a Bing carb, but the factory recalled the carb and replaced it with a Walbro.
Story I heard was the German Bing castings couldn't handle our Canadian gasoline.

If I get time I'll check the two mags I have .I know one has a Bing but I'm not sure of the other one . If memory serves I think my 038 AV has a Tillotson .

 I just looked at the IPL Tillotson HK42B .FWIW Oregon made the repair kits for the BIng .I had 4 at one time which were just the soft components but they made a complete kit which had all the parts. Google it .

FWIW there are about a dozen rebuild kits on flea bay for a Bing 48 .See how simple that was ;D
