How to get more Grunt...
...from your 23cc Zenoah
By Ivan Hancock

Blokes, if you are unhappy with the grunt from your 23cc Zenoah engine have a dekkko at the piccies in this article.
All you have to do is remove the original small throat carby and slam on the biggy one pictured.

Order the new carby a Wallbro WT-813, from your nearest hobby shop, and thats it. Revs will go up from 6300 to 8900 with the same 15" x 8" prop.
