trouble starting the ROTO?
I have three of em and they all start very easily.
Is there a secret to it .
Not really.
I removed the Walbro "snap to off choke" contraption from the carburetor.
Instead, I made a very simple drag clutch on the choke - so that I can just turn the choke on or off as desired.
Just like any other gasser -- you choke and flip -watch to make sure the fuel comes to the carb-
engae ignition and in a few more flips, it will burp start.
Then stop.
open the choke -
reduce throttle to low idle and again flip -
that's it.
here are a couple of pictures.
One pic shows th little forked choke to throttle link-which I removed .
The other show the piece of silicone tube and washer and wheel collar, which make up the drag clutch -to hold the choke plate in any position as you select by turning the 1/16" rod attached.
