Zenoah G260 Big Bore Carb Upgrade

[bbowers]

Whats the best Big Bore Carb upgrade for the Zenoah G260?

Will I see a noticable performance increase from this upgrade?

Thanks

No need for a LARGER carb in a 260. They come with a 1/2" bore carb and that's all they need. Anything bigger results in difficulty setting needles, bogging down on acceleration, and a decrease in top end power. The 260 comes with a Walbro #644. We like to remove the choke plate from the 644. A good upgrade is the Walbro WA-257. It has no primer bulb and no choke, but is still a 1/2" bore. There is another carb (forget the number) that is like the 257 but does have the primer.

Here's a link for a place you can get a good deal on the 257. Also has the 488, which is the one like the 257 but with a primer bulb.

So what does removing the choke plate give you on the stock 260 carb?
