You're welcome Bill,
I think you mean that the Kalt engine came with a 197 Walbro.
I've an other Hughes standing here of my friend with a Kalt22 and it's got a 197 carb. without primerbulb.
On the G230 Zenoah's there's the 167A Walbro carb. with primer bulb.
...
I just swapped an 167A on my Futura for a 644 Carb.
I try to tune for more power because the 644 has a larger ventury.
And the Futura needs it with MAH810 blades...
Btw, the 644/643 came with the G231.

Eric.

They changed carbs just like they try to now, unless folks step in and say something..One of the reason they went to the 197 was because of the 167, they had a "A" model of it too...anyway thats the reason I had to change so many out to find a good one...

I'm testing carbs right now for Al At Hanson, so to give feedback to Zenoah.. They are wanting to put the 817 pump carbs on the RC engine, and so far my test show the 603 is still the best carb for the that engine on helis anyway
...

They tried this 3 years ago with the PUH...

Thanks for the info
Bill

How does the 603 compare with the 643 Walbro Bill?
Just maybe we get carried away on this thread..
