ok I see that walboro has a new carb out the WT-1027 www.davesmotors.com/s.nl/c.885...it.A/id.8629/.f

here's my question what is the difference between the modded 257 and this new
WT-1027 big bore carb does anyone know.

Thanks for you time.

only diff I heard was price - don't believe it's any bigger

Can only guess here ... but looks as if kit is an OEM Zenoah offering along the same idea as the 813 pumper HP kit that was generally a flop if one reads about whats been posted about it ?

Looks like a Zenoah OEM intake bell, Screws and gaskets too.

Throttle bore and Venturi size is already at it's max with the WT style body shown.
Really no way to have it flow any better ( CFM wise ) than the current carbs we use now.
WT-257,771,813,929,488 etc .... Metering wise tho likely using the small inlet needle which would make it superior to the 257 in high rpm application.

Just an educated guess

Thank you for the info guys was looking on getting one
but i think i will wait to see if others will buy one and see
the results.
