Hey Robert,
I believe that the 1910 is like the 1610TS. I had the same problem with the air filter and talked to some folks at Wix Corporation and we determined that the napa 6270 will work. It is about 2/3in. shorter. All you have to do is knock out the brace which is inside of the cylinder. You need to cut off a couple of inches and weld it back together. Then it should work like a charm! That air filter is about $15 I believe instead of the $80 like the other. Thanks, talk to you soon. Hope this helps. Rambo, NC
