1977 Columbia Commuter: Why is my engine bogging?

Sun, 21 Dec 2025 10:56:16 -0700

So I recently got my moped started and running but it wouldn't move under it's own power so I decided to add a metal washer or shim in the clutch pack because it's hard to find new parts for this moped, and after that it started to move under its own but the kickstart was tight and when it did start, it would move but not very fast, like 8 mph, and it would bog at some points and even die and I even have the hold the starter lever to make sure the clutch engages. Can anyone tell me how to resolve this?

I have checked the kill switch and foot stand switch both seem normal. The battery is on a BMW maintainer, is fully charged and new. Engine turns over but will not catch. There are no service locations in my area as I am visiting Grenada. Looking for a service manual that will load to a MAC or ipad as last resort. Thanks Richard

Suzuki FA50 Moped: Drain nipple under carburetor leaks gas when throttle is turned.

Fri, 13 May 2022 15:30:06 -0700

When I turn the throttle my drain valve leaks gas at a tremendous rate. I've tried plugging it, but all that seems to do is cause my carb to become flooded.

What could be causing this...I've gone through a full tank of gas in less than half a mile. Also what house is the nipple next to the main fuel line for?

While riding the motorbike, the engine will shut off and it will not start back up. When I try to start it back up, it makes a constant continuous chugging noise but the engine will not turn over.

Suzuki FA50 Moped: What's the best way to install a new throttle cable?

Fri, 04 Dec 2009 11:50:54 -0700

I got some awesome tips on diagnosing my moped's stuck throttle cable problem. The solution seems to be to install a new throttle cable.

Therein lies yet another problem. The throttle cable routes through the frame of the moped. What's the best way to route the new throttle cable through the frame without taking the frame apart (if taking it apart is even possible)? Once I get the cable through the frame, how do I connect it to the actual throttle on the moped?

For reference to the original problem, take a look at my throttle cable teardown.

Thanks a lot!
