Zong not starting again

[Pabesco]

Mechanic scheduled to arrive at 6 today. I checked the fire again and it now seems to be pretty strong. I scraped a bit of the paint from the head and grounded the plug there and the spark looks pretty good now. I went a step further and touched the plug while cranking and got a pretty good shock. Now I'm thinking along the lines of it being a fuel problem now. I will pour a bit of gas directly into the cylinder and replace plug and tryto start it right after recharging the battery. If it runs then cuts off then it's a carb issue. I will post ASAP.

you can also try spraying some aresol starting fluid in the intake. probably a little easier to do vs taking the spark plug out

I wouldn't pour fuel into the cylinder! 8O Fuel is supposed to be atomized, and very little fuel causes a large amount of combustion. You could easily damage your engine by pouring gasoline into the spark plug hole. :?

I suggust you have the mechanic examine the carburetor, and make sure the fuel system is operating properly before you attempt to bypass it. If you feel you must introduce fuel, I strongly suggest you follow the advice of the Wild Alaskan, and spray some aerosol starting fluid near the intake of the carburetor.

Will do. Thanks guys. I was following the advice found in dans online motorcycle course that was suggested to use as a reference. Glad I didn't try it yet.

I searched Brother Dan's website and found the following information.

http://www.dansmc.com/starter.htm

"When you rebuild an engine all the parts are new and rough and don't really know each other very well. Because of this, a new engine may be hard to start for the first time. With a fire extinguisher close by, try a small squirt of gas, from an eye dropper, down the spark plug hole. Reinstall the spark plug and it should start. You can use starting fluid, but you need to be very careful and NOT use too much. Same with gas. Just a small squirt. If it doesn't start, find out why. Don't keep pouring more gas or starting fluid down the engine. If you do, a stray spark could end up blowing the exhaust pipe off or setting fire to the engine!"

This information applies to a rebuilt engine with all new parts. However, the procedure is still dangerous. :? I suggest you examine the fuel system and look for problems. Even if you get the bike started using the method described above, the bike won't run for long if you don't fix the underlying problem.

I do agree. The mechanic was a no show so i tried it using a bit of starter fluid and it didn't work. But I found that the plug when removed had black smoke on it. I tried cranking for about 10 seconds at a time for four times then removed the plug and it was covered with black smoke residue. Any ideas.

i would clean the carb, Its best to remove the carb and clean each part individually, but if you are feeling lazy, or are intimidated by doing this, you can remove the gas tank unscrew the top of the carb and remove the slide and spray carb cleaner down through the main jet until it starts flowing out the over flow tube of the carb. also spray it down any other holes you can see from this perspective. there will likely be a small hole towards the engine that is for the idle jet, spray it well.

reassemble, make sure the slide is in correctly, twist the throttle when done to make sure it feels normal. pull the choke and run the e start while twisting the throttle between closed and quarter throttle. there will be alot of carb cleaner in the bowl, the motor can burn it just fine if the choke is on (and will run it through the idle passages) . after a bit it will get replaced by gas and everything should return to normal.

Great shortcut, WA. I'll have to remember that one. :wink:

Definitely not lazy and more than willing to learn as much as I can. I wi REMO e the carb tomorrow and clean it properly. I will remove all jets and clean all holes. Is there a specific type carb cleaner I should be using?

[Weldangrind]

I just use whatever aerosol carb cleaner I find at the parts store. Please wear eye protection. Your seven kids will thank you.

[Pabesco]

Lol. Will do. Just removed carb and will start taking apart tonight so I can clean it in the morning.
Thanks guys.

Here's a link to the TW200 forum for a thread called "Lazy Man's Teikei (TK) Carb Cleaning."

I suggest you read these threads before you disassemble the Teikei carburetor of your Zong. I also suggest you purchase a spare, Teikei carburetor from Zongshen America (ZA). I bought a complete, spare carburetor from ZA years ago at a very reasonable price. If you have a spare carburetor you can swap it out the same way you swap out a spare CDI unit. The spare carburetor will also provide spare parts, should you need them.

I already took the carb out. Removed all parts that could be. Used the carb spray and cleaned the entire carb. All rubber parts were safely put aside prior to spraying. Carb reassembled and reinstalled. Tried to start and it didn't. Battery was sort of low so it's charging g now. I didn't see the links you sent to me prior to doing all of this spud. I'll check them now and hopefully I did everything right. Thanks and ill post after reading

make sure gas valve was returned to on, and also try loosening the carb drain screw and make sure you get a constant flow to make sure there is no blockage and fuel is getting to the carb. i've had a float needle gum up just enought the bowl would fill in about 10 mins and give me hours of trouble shooting grief.

[SpudRider]

I suggest you turn off the fuel petcock (switch). Then remove the fuel line from the carburetor, open the fuel petcock (switch), and verify fuel is flowing from the gas tank. If fuel is flowing from the gas tank, reattach the fuel line to the carburetor. Then open the fuel petcock (switch), and wait a few minutes for the fuel to fill the carburetor float bowl. Then drain the float bowl, and verify fuel exits out the drain hose.
