RE: MVVVS 26 throttle and choke set up.
Euclid,
The last time I looked, the MVVS 26 cc engine did not have a choke...
The Walbro throttle uses a ball-joint and routing is quite straightforward; similar to any normal R/C carburettor.
Maybe if you take a photo and post it here, we can see what problem you are encountering.
