The electric choke that came already attached to my replacement carburetor seems to heat up too fast. It always seemed to not work right but now it really appears to be off.
I have the idle speed set so high that the bike's rear wheel will spin right after starting. It will remain running until I plug in the pin connector for the electric choke. The idle slows within 30 seconds or less, then about 15 seconds later the engine stalls. The electric choke will already feel warm to the touch afterwards.
My old electric choke never heated up that fast nor stalled the engine after fully kicking in. Luckily, I have another electric choke on hand. Though unfortunately a screw that holds on the choke is too tight and stripped. Now I got the task of removing it before seeing if another electric choke will work. Seriously, those screws on gy6 carburetors seem as soft as lead.
Do these electric chokes usually have such problems?

I could use either the choke from my old carb or another one that I got awhile back. The new carb is basically identical to my old one. All the rubber parts on my old carb were dry rotting and some screws were stripped and stuck. The rebuild kits I saw were around $15 while whole new carburetors were around $25. Plus the carb came with some fuel line and a fuel filter. I decided it'd be easier to spend the extra money than deal with working on the old one. No regrets with that decision though. Gone over 200 miles now and it's working great, apart from the choke, of course. The spark plug indicates proper running conditions. newbscootdudeMay I ask where you got steel screws for a gy6 carb? The selection was poor last time I was at a hardware store looking for nuts and bolts for my scooter. I'm pretty sure I wouldn't have had any luck finding matching screws had I looked. |

I got the electric choke off today. I compared it to the one on my old carb and noticed that the ends were different lengths. The right is the one from my new carb and the left is from my old one:  I'm not sure if this caused a problem. The other electric choke I have looks the same as the choke from the new carb in a side by side comparison. I think I'll use it and see if it works. That way I can find out if the length difference matters. |

Yes, it appears that the length matters. The longer chokes caused the engine to shutoff less than a minute after starting. With my old carb's choke the engine doesn't have any trouble while warming up.
However, I still had a problem after putting on the old choke. The engine idled rough after being fully warmed up and kept stalling. The petcock was the only part I had not checked so I replaced its vacuum line with a clear tube. Moisture from gas started to build up inside the tube after running the engine for about a minute. I then plugged fuel line directly from the gas tank to the carb just to be totally sure. And yes, the engine idled fine and didn't stall.
If the petcock was fine, I'm guessing the engine wouldn't have had any stalling issues with the other electric chokes after being fully warmed up.
