I have this NO NAME 90cc atv. Guessing that because of the 87ccm stamped on the jug. Any way I have spark,fuel getting through carb and into the cylinder. Valves are at .003. Double checked those. The remote control "board" is crap all corroded. It will 1 in ever 100 times think of starting, normally if I have left it alone. won't start on ether either. There is not a single ID marker on this thing. It does have the typical Honda knock off engine. I have the Honda Manual for that, but am out of ideas!!!!!!! the only other thing is there are 3 wires where a rear brake light used to be? or a kill sw. with key on 1 is hot the other 2 ???

 

You can try gaping the spark plug to the proper specifications in the owners manual. Best of luck.

 

Ok letting it sit overnight it started this morning ran for about 15 sec on choke . So I could assume that valve and electronics are ok . So what gives, why an overnight rest would it start????

 

Maybe you should think about getting rid of the crappy corroded remote and go from there.

 

It ran with the board plugged in, so must not be an issue??? No clue

 

I think it may have been flooded. Sitting allowed the fuel to seep by the rings.
I'd clean the carb (remove the jets too) paying special attention to the float needle/needle seat.

You said it ran for 15 seconds... Did you turn it off OR did it just die on it's own?


It was you that said; The remote control "board" is crap all corroded... By "remote control "board"" , I am guessing you are talking about a device that allows someone to start or stop the engine from a distance. .. If it was me, I would disconnect the remote on the bike and see if that stopped all the magical or impossible stuff that is going on.

 

All set the coil wire was cut or torn who knows! When I held the plug to the head it was fine, but as soon as i installed it was N/G... Found it with a shock!!! Thank you all for your info regardless!
