Throttle mechanism and cable
« on: July 22, 2014, 04:09:30 PM »
I have a 1958 Simplex with a non-working throttle.  I removed the grip and internal mechanism and found the cable is damaged.  It is similar in appearance and resistance to movement to a mower control cable, not free moving like the cable on my other motorcycle throttle.  Is this a design feature to allow throttle position to be maintained without holding it or should it return to the closed position when released?

Any input welcome.

Simplex did not use a throttle return.  I just think of it as cruise control!  LOL

Do you have the type that pulls the carb linkage or the type that twists it from the top?

Yeah, the cruise feature would be cool.  If I'm understanding the question, mine pulls on the linkage.  I'm not sure what the type that twists looks like.

My cable jacket is stretched out on the handlebar end.  I am going to get a mower style cable until I can get the correct replacement.

Wayne has the correct cables.  The twist type cable mounts vertically to the carb,  where as the pull type is horizontal.

Wayne is not a computer guy.  His contact info is in the vendors section at the bottom of the home page.

If you don't get him at first, keep trying.  He'll eventually be home to answer the phone.
