Can't find Spark plug for my 2012 Powermax 150 By knottidedown (Read 463 times)

[knottidedown]

My engine is : 157QMJ
                120428204
i have looked all through this site. Any help or know where I can find a service manual for this model?
looks like the belt is a 842-20-30 for the long case (10 bolts), right?
Thank everyone

I may have found the spark plug. Can someone confirm before I order one? NGK C7HSA.
Thanks

Spark plug C7HSA

Just google for it

There are no service manuals for each specfic chinese scoot they are all sameo sameo. So any 150 service manual will do you. You can find one on here just go to the manual section.

You got it

There are very few bike specific manuals. Most of them are generic and you have to wing it. But your bike is a standard GY6 150 and it is the same as the rest of the QMJ157s or anything close to that engine number...they are all the same Bill. I'll give you some links to the standard fare. With your technical experience you shouldn't have a problem taking the relevant parts out of these manuals. If what you see doesn't match exactly you have to improvise. I'm sorry, that's the nature of the beast. These are all in the Library. Rich:

50 to 150 Manual: Dated but good

Scooter Doc Manual: (a work in progress)

Z Bike: Good manual with pix

Tank Manual: This is old but still good

Arrow Manual: Decent

You don't have to order Bill, take the old one down to the auto parts store, they'll get you one from behind the counter. You are overthinking this, they are large lawn mower engines....maybe even not so large compared to what I see at Lowes. They are simple Bill, tear one apart, it's probably not as complicated as a helicopter engine. Rich

You all ROCK! Thanks so much....
The scoot started to make a noise like the clutch was wearing. Only makes the noise when accelerating or holding constant speed. Goes away when I roll off, idle or go slow at a constant speed....and thoughts?

It's low miles right? I doubt the clutch pads are worn. You may need to pop off the clutch bell and look at the pad arms. Sometimes the springs will break and a pad will make noise. I had one of the arms get a crack in it recently and it made a metallic noise so look them over closely. Maybe pop the variator outer pulley off and then slide the inner pulley and ramp mechanism off. A roller can get lodged or get misaligned and make noise also. I had a Vulcan 1500 and I chased a metallic sound around for a year. The dealer said it was the valves and wanted $800.00 to fix it. I finally found it, a washer had fallen down into the tank bracket right side and was harmonically vibrating and sending noise all over the bike. Check for loose components and fasteners too. Rich

I will do just that. I am so excited to be able to tinker with something other than Diesel engines for a change. Thanks again for all the help everyone.
