Hi,
I recently purchased 2 SV-26 gas engines (about 2 months apart) and one has a Walbro WT694 and the other has a WT 255.
I spend about 1 hour on the Walbro internet site and I was not able to find out what is the difference between these 2 carbs.
Other than one has the body casting come up and around the mix screws while the other has screws that are just standing up 9baiscally unprotected) I do not see any other visual difference.
Can anyone tell me if they are basically the same carb or should I expect difference performance?

Thanks!
KC
