Not sure, I thought it was a 2.6. I'm still unclear where it tells you if it's 2.0, 2.2, 2.6
Mine is a Model L023G Engine G54B
The Weber rep did mention the 38/38. I think that's how I'll go, but waiting on there response.
I do hope you're right on the install times. I've been fighting a loosing battle with a poorly installed carburetor from the previous owner for about a month trying to get the right parts and trouble shoot it. Finally said to heck with it, start over with a new Weber.
