Default Magna Force Pro Force 163 CC Engine

Ok I have a few questions about this engine.

Magna Force Pro Force 163 CC Engine

Does anyone have any information about this thing other than the obvious being it is a 163CC OHV engine?

I bought it from a guy off FB Market place for 10 bucks. He said he replaced the carb but then he thought it dropped a valve. I figured it was worth 10 bucks in parts.

I finally pulled it out of the shed last night and decided to pull the head out of curiosity. I had turned the crank by hand when I got it and it didn't feel like a valve then so why not take a look. I love to see these things running.

I don't know exactly what I found, maybe a washer or something, but it didn't belong.

I didn't see any cylinder scoring. Just a little bit of dings on the cylinder head. Where it had beat into the carbon. Notice it is shiney and not blackened. So it never ran like this best I can tell. I didn't notice any dings with carbon in them. Doesn't mean anything I know.

So, I put it all back together, checked the oil, put some gas in it, and pulled the cord.

Amazingly it fired right up and transitioned right straight into a nice easy idle as soon as I opened the choke. No smoking, no valve popping, or anything associated with valve or cylinder damage.

So I guess it's a win on my part.

But who really built this engine? It looks like a standard clone but it also kinda has the looks of a Briggs Intel as well, just a bit anyway. I guess they all look alike.

And what parts can I use on it if I want or need?

Does anyone have any idea?

What he said ^

There’s more clones (generic or otherwise) out there than you can shake a stick at, and there’s sometimes no real attempt at standardization.

Take a photo of the serial number string, that’ll give a clue.
Good job on the save too.

OHV*. If it was overhead cam (OHC), that would be real special, no?

Yep, you are correct, simple typo and I didn't proofread, but I will edit for spelling. Look at the keyboard on your phone and you will see the c and v are next to each other. Small buttons and big fingers often equate to to word fails.

Thank you.

I'll get a shot of the serial number string. But I don't know how to decipher the numbers on clones. I can learn. But for now I am ignorant of the methodology of it.

So here is the serial number series. And a shot of a tag from the side of the air shroud.

I should have paid closer attention. It's starting to add up now. Especially if one makes assumptions that the numbers and letters on the series number allude to displacement and manufacturer details...an assumption...

Wenling Jennfeng Industry inc.

Or simply Jennfeng. I couldn't find very much about these guys. Just based out of Taiwan. I would assume the engine was built in China but I have no idea.

Idk, the serial number is a reference point if anything.

They always seem to have those stars in the serial number. I call them Chicom (Chinese Communist) Red Stars.

Just doing a quick google search, it looks like these engines are mostly used on pressure washers

Not sure what I can use it for really, I just like to see and hear them run when people throw them away thinking they're done for. Especially a simple fix like this.

Does it have a standard shaft or is it tapered (or funky)?

Looks like a straight shaft to me...
and with that being said....
If and when you do get that running again... firmly tape that key inplace or remove it altogether.... thats a very dangerous projectile waiting to fly off and hurt/kill...

Yea, what he said, It's all good.

That thing is stuck in there good...wanna see




Here it is running during the day time.




If it kills me I will never know it. And yes I've been hurt by a lot of stuff. I've done a lot of shooting over the years. I've been hit by a lot of ricocheted rounds. I couldn't pry that key out...so it can stay for now.

My next project in a new thread!
