IDK What Happened, Do You??..Ideas??

[Thebatman]

:dunno: Good morning guys and gals. I was working on a 150 gy6( a yamati strada).. I cleaned everything to try and revive it, Started beautifully, ran nice. I rolled it outside, cleaned the cvt, rolled it back inside, stuck the air box on, now it has no spark. :stumped:
It was running, started beautifully. I have checked the cdi, coil,stater,grounds. even swapped staters with a BRAND NEW and still nothing. Everything seems to check out fine according to the troubleshooting section by using a test light on everything. IDK if i should get the light to light up on the coil wires tho. I wasnt getting a thing from either side, but the coil is good.(tried a different coil, same issue).
I havent checked the regulater/recifier. Could that be my issue or do they only help with the lights. It was starting after turning over 2 times, now it wont hit at all. no spark. Does ANYBODY have any other ideas for me to check
Should the ground wire cause sparks when rubbed against the valve cover? EVER? I wouldnt think a ground should ever do that..

Also a very STUPID question, do this not have a kill switch like a 50? This one has the hi/low/horn on the left and the starter button and light switch on the right. Even has "hazzard" lights but no kill. :dunno: :stumped:
Everything i seen says coil wire, switch. Any ideas or should i just go ahead and strip the harness looking for a melted wire/broke wire or could it be the rectifier,regulater,ignition.
(yep, i was trying to make a lil extra $ to finish with my babys b-day party and now look). It's like turning a switch off, it was running great, 2 hrs later it wont fire, no spark..
Oh yeah, aren't you always suppose to have a nice blue spark on anything/everything?.. Cause i did get a very tiny spark, now nothing..
Thanks for ANY input on this head scratcher.. :stumped:

I got it right... I feel SSOOOOOO dam stupid. :no: :banghead: :doh: :beatup:

What was it?

For future reference, the rectifier/regulator should have no affect on the ignition system.

Well, this is my 1st 150 even messing with and i actually had the kickstand down while on the centerstand.. I had no CLUE there was a switch on the kickstand. Unplugged it, fired right up. plugged it up and still fired.. Something was wrong with the black/yellow wire and that's where it led me. Now THAT made me feel REEEEAAAAAL dumb...

I do think i "opened" the pj up to much, it was idleing fine then it died, plug was black and about sooty. The mix screw was at 2-3/4, i turned it to 1-1/2 and it started up. I may have to go to 1 out. Should i lower the needle instead of going down to 1 on the mix?

Eh. Live and learn. Don't worry about it. We all do that kinda crap.

If it works OK with the mix screw adjustment, just stick with that.

Hey guys. I got it running but it idles like it has a "cam in it". Kindof lopping. I even have the idle screw all the way in now and it has no effect on the idle at all.
Nor does the mix screw, I went from all the way in to 3 out with no change at all.
Should i try and solder up that pj?
Is that why it's acting "cammy", because the pj is just to big now?
Or is it just my cable out of alignment a tad?..(i wouldn't think this is it tho)
Thanks for any other input here..... :cheers:

That may have been it there. I found a old gy6 50 carb and took the pj out and installed in the 150 and the idle is smooth again. Was able to change idle and mix. Have mix at 2-1/2 out atm.

Why the sad face? If it works leave it alone and be happy.
