thanks faster im almost postitive its the float its staying closed the whole time im trying to crank it and i have watched the how to clean carb video but when it try to get the float pin out to clean it etc. i cant get the pin to budge any suggestions on how to get it unstuck ive tried a punch but still wont move very frustrating im really trying to keep from having to take it to the repair shop considering i have nothing in it but its looking that way

 

so i presume you tried to "punch" the pin both directions. well, you may need to soak it in a penetrant, such as Aero-Kroil, WD-40, Berryman's chemtool, stuff such as that. but it must be really stuck if you can't punch it out. they normally just push right out with a little persuasion always being careful not to bend or break the supports for it. hmmm..........wished you were close to Texas, i'd fix it for ya! if anything, a new carb wouldn't set you back that much. plus you'd have a spare for the road trip. holler back and let us know.....sorry.

 

Ok, so Im working on a hensim 70cc atv. I have everything back to where its supposed to be except for this one sneaky ground wire. Its connected to a little black box with what seems like a computer chip inside. One side is 2 black and 1 green wire. Other side is the ground wire. Can someone help me with what this box is and where the ground wire grounds to??

 

where is the "box" located? near the battery? up front under the handlebars under the plastics, under and to the side of the fuel tank? could be CDI, rectifier, etc....
does the box have air fins on it?

 

On the footbrake side. It sits in front of the cdi module. connects to the frame with a rubber snap on clip. same as cdi

 

not familiar with your quad,,,,,,is it a F-N-R switch? are the 2 black wires just hanging out or have you traced them out? just asking.....

 

just asking....does that have a remote control shutdown on it?

 

My neighbor gave me a 150. Battery shot. Put a new battery in, cranks good. Wouldn't start. Pulled plug and grounded it against frame while cranking. Nevery saw any spark or sign of fire. I thought I had an electrical problem. Put plug back in and took off gas tank.....etc to get to carb. A little gas in the intake and she fired proving plug was firing. The rubber elbow between intake and carb was cracked. I repaired it with so high heat silicone for the time being. Put it back on. Float seems to be working, carb seems clean. The shut off? solenoid on the carb doesn't move when you power it. With it removed I held my thumb over the hole it goes in and the engine tried to run. With it in place I could squirt some gas in the back of the carb and the engine would run in spirts. No I can't get it to fire no matter what. I'm really confused. Tried a new plug thinking that one had a intermittent short. Where does the exciter signal come from that feeds the coil? The coil shows almost a dead short, 1 ohm reading, when testing incoming wire to the ground. >>>>>>>>>>>>>Help.

 

comes from the stator. read some of Lynn's posts about no spark and how to test the stator and the trigger signal. trace out the wiring for the trigger and you may find a short or a kink in the small gauge wiring. OR, pull the stator cover off and check for surface rust and then clean that off to begin with.
