I see the 643 carb has been discontiued. I am in need of a carb for my 260. I heard that the 644 is the same as the 643 except without a choke. Should i get the 644, or is there something else that is better.

I just looked on horizon site and they show the g231 and G26 with the 643 carb but when I looked in the parts list it shows a WT-813. Anyone know what that is and is it any better than the 643? I wouldn't think they would discontinue 643 and replace it with something unless it was better?

I asked the same question about the 813 a while ago and my understanding is that its great for apps where you are on / off the throttle like go peds and cars as it can deliver fuel quickly when opening the throttle, but a few that have tried it say that it did not work well with a heli running at constant RPM.

The 644 with intergrated choke is an excellent choice:

Best Walbro for 260

If you E-mail or phone Hanson or T.R.M they will no doubt tell you the best current carb for your heli engine.It is their business to know the best for heli applications after all.Be well worth asking.The throttle pump type does not work well with the heli motor ,just makes the engine pulse,had a new one which i tried that now is fitted to a boat mounted 260 PUM and works very well on that because of the large throttle range.

Cant you just rebuild your present carb with a rebuild kit??

Setup is everything, All my heli's can fly far better than I can pilot them
