you should....
The engine itself, absolutely is mechanically sound. The carburation is the issue. So far, I have not yet been able to figure out a solution for that other than to supress the issue by altering the shape of the LS needle a bit, and to supress the issues with the use of a governor.
But mine has provided 7 years of reliable and very frequent service, until I crashed the heli due to a broken lanyard causing the transmittertray to drop from under my hands...
I hate it when that happens...
