Just received my first motor kit. Chinese 2-stroke, Back

There's a pretty deep scuff on the side, scuffs all around the spark plug housing and the top end of the motor seems a bit mangled. Is this common with factory standard testing?

Why not ask the seller

Looks like you should turn it back in to the seller, that does not look right.

pretty rough but not terribly unusual.

The reality of the situation is that the appearance of the outside of the engine does not reflect the internal operation of the engine.

So long as the internal components are machined correctly, there is no real need to worry about the external casting flaws.
Most of my engines have casting flash and surface imperfections and some of them have a much better external finish, however it has not made any noticeable difference when it comes to performance between engines.

I did, but it's purchased off of Ebay, so also asked here for a second opinion. Thank you tho

You'll have imperfections even when "new" straight from the factory?

Well what did the eBay seller tell you? Go back and look at the picture that the seller posted for the listing and if it's misrepresentative of what you received there's plenty of buyer protection. Honestly at this price point they're gonna be a little rough though, so it is what it is.

you could look at it and also think "how is it even possible to make a whole kit for this much?" let alone worry about a few blemishes.


mmm, blemishes

unless.... looking at the plug hole closely, is that just minor scratches or actual porosities in the casting that havent been machined out?

first case, keep shrugging, keep building.

second case, wellllll it iiiiiiis meant to be a sealing surface and iiiiiiiiif it doesnt seal properly its sort of useless so at least demand a new replacement head! (or dont worry and replace it with a high compression head )

This is a motor from eBay that was delivered a few days ago, hope its helpful as far as weather or not you want to contact the seller you bought from.
