As title states...was running yesterday and my plug wire came off, so of course the engine cut off immediately. I was at wide open throttle when it came off. I came home and changed the plug out (tip looked slightly lean, but nothing horrible). Anyway, now my engine will not crank...doesn't even sound close. I felt the end of the plug wire while cranking and there doesn't seem to be any spark coming through. I have truly grown to hate this truck and once I get it running will honestly probably sell it cheap. I love hobbies when they are fun, but my idea of a hobby is not fixing and spending money EVERY time I go out to play.

Anyway, I appreciate any help you can give me...you guys will have first dibs on my truck when I sell it...haha

thanks again,
Alan
 
Is the wire damaged ? If not just put the wire back in
job done! No need to spend any of your money, a quick
simple fix.

If it is damaged you can pick the wire up cheap.

Looks like the wire is fine...just to be sure I cut the tip off so I would have fresh copper coming out. I just don't understand how everything was fine yesterday until the wire popped out of the cap and now she's toast. Is it a pain in the ass to replace the entire wire going in to the engine? What is involved?

thanks again

saying it wont start ?

Yes...there seems to be no electricity coming from the wire now. I find it coincidental that the wire pulled out of the plug yesterday (was running fine up to that point), and now there seems to be no spark whatsoever.
 
Just remove the fan cover and you will see the coil
then you will see where the wire comes out.

Make sure to fit the coil back corret or the engine won't
fire what so ever.

cool..will give it a whirl

I use a business card to set the coil from the flywheel
and give the flywheel a couple of spins just incase it
doesn't rub.

Let me no how you get on.

sounds like if it pulled loose on the plug cap it may have pulled loose on the coil end too as stated above, you can replace just the plug cap and wire, and not have to replace the coil, if this is the problem. cap and wire are pretty cheap, a few bucks is all.

follow advise above and check the coil end of it for wire pulled loose on on coil end as well.
 
The electrical system on these 2 stroke engines is pretty simple if its not getting a spark at the plug cap its probably one of two things. Ignition Wire is broken or inductor coil thingamygig is not working or not aligned withthe flywheel stator thingamybob. perhaps the reason the plug end came off is it snagged on something which pulled onthe wire which in turn cuased the gap to be opened up between the induction coil and the flywheel.

To test if its getting spark at the cap pull the plug out, insert it into the plug cap and near it to earth and try start it, A strong spark should be generated. Another way is to use your finger but you want to be a healthy fit man to not kill yourself doing it. Its a rush I tells ya

Well, bad news...head is cracked...I'm selling it. Don't have the time to constantly fiddle with the truck EVERY time I take it out...and I'm very very easy with it. Cracked head and needs steering servo...first $400 gets it.

cracked head? you mean cracked where it mounts the coil? or the cracked head all the way into the piston chamber?

This truck has never had an impact...I rolled it over twice once and it rolled back on it's wheels and drove fine for another hour. I have now bought in to the "clones are severely substandard" argument. I'll probably hold on to it and just build the poop out of it if no one is interested. I have actually been really really easy on this truck.

well for that to crack at the mount point one of those rolls must of impacted enough to start the crack,
i have somersaulted my baja's several times, only thing broken was a control arm and the steering bell crank,should of broken more with everything i have done to it, but for the engine to crack in mid use some thing is missing here,that head had to be tweeked to the rear in order for it to crack the way it is, don't know but you can get a head for about $25,as long as the crank, rod and the piston are still usable.
whats your location i have a used 29cc head that uses a 36mm piston so it should fit on the 30.5 if you local just pay the shipping and you have it
