Welcome Lisa to the forum, glad you joined us

I do not have a powerking, I believe a few members here do....what where you running your fuel/oil mixture at?

Hi,
Thanks for the reply....i was using a 16:1 mix,Tanaka 2 stroke oil and regular Shell gasoline.

the deep scoring on the piston and cylinder walls was at the 2 oiling ports in the cylinder

If you are running a 16:1 mix then it shouldnt be anything to do with the mixture. Have you checked the colour of the spark plug - anything grey or white means overheating - you need a nice tan/brown colour. Running a two stroke lean will quickly kill a motor.

Since you have done such a small mileage it might be worth talking to the supplier because it sounds like fault in the motor.

define what you mean by 'rough' - if there is scoring on the inside of the cylinder then it might be from the rings or something being wrongly installed inside the engine. I assume by the term 'shelled' you mean broken?

glad to see you on the forum

welcome to the foum.
sounds like you might have gotten a lemon contact the seller and see if they can send you a new one or replacement parts.
Your in Ok. I'm 3 hours due west of Ok. city keep on here and ask questions with pictures if you can we might be able to help.
If the cylinder is scored you will at least need gaskets, cylinder,piston with rings and needle bearing and wrist pin with the keepers. Don't know what happened to your engine but like I said if its new contact the seller and see what they can or will do to help.
I went back and reread your post sounds like the wrist pin needle bearings let go or the circlip wasn't installed and may have went through the engine tearing you know what out of it. Do contact the seller

Thanks All for the quick replys;to jemma plug was light chocolate,shelled="Destroyed!!"...lol...made horrible rattling sound,just before it quit...
Wrist pin rings were still intact and tight....,"Lord Vader",wrist pin needle roller cage was broken in peices....intake and exhaust ports were smooth,oiling ports for lower crankcase were really rough.....rod has several thousandths side play now.....would you all rebuild with new top end or scrap ??; thank you sooooooo much........Lisa

So basically the bearings have toasted themselves and taken most of the rest with them...

It depends on your budget I guess - work out what will be cheaper to do and assuming you have the skills and the required equipment a rebuild is possible.

Personally I would contact the seller and get them to send you a replacement or the required parts for a rebuild at the very least.

Can I ask - did the engine run out of fuel by any chance?

This is one of the reasons I stand by the commercial engines such as tanaka - because you have a backup and guarantee on the motor from the manufacturer.

Good luck with fixing it up
