Idle adjustment

[DT35]

How do you turn the idle up on a 1958 super sea horse 35. It's been converted to remote controls?

Should be an idle stop adjustment on the port side of the engine - sort of a small plastic thumb-screw type bolt. Turn it clockwise to increase the idle.

Like was suggested in your earlier thread, disconnect the remote throttle cable at the motor. Adjust the idle stop screw as described above, then reattach the remote cable. The slow speed travel of the throttle lever at the box will hold at the rpms set by the idle stop screw.

Your idle should be about 650 rpms in the water, warm and in gear. If you can't keep it running at about that speed (i.e., runs only at a faster idle), the issue is probably dirty idle passages in the carb or adjustment of the idle mix screw at the carb -- different issue(s) from adjusting the throttle speed/idle stop, but works in tandem. The motor should slip smoothly into gear at a comfortable idle, with no stalling.

Ok great thanks I will try that

I disconnected the remote throttle and spun the plastic idle screw with absolutely no result.nothing happened so I imagine it's time to rebuild the carb? Where would I get a rebuild kit?

Kits are easily available -- can order one through iBoats. Cleaning and rebuilding involves complete teardown -- recommend soaking all metal parts, including carb top and bowl. Carefully clear all passages, including the ones under that domed plug on the top (replacement plug comes in a kit). Those are your idle passages.
