Walbro messed up tiller carbs!

[Black Dog Chainsaw]

Had a buddy bring a mini tiller (Mantis or Murry? - it was little weed eater looking motor) over last night b/c he couldn't tune the carb out right. It was a brand new from factory fully adjustable carb. After messing with it for 2 mins i realized I could turn the L-needle all the way down and it didnt die! Took me another 20seconds to realize that they stamped the H & L on the wrong sides! Way to go Walbro!

Anyone else run into the H & L needles being miss-marked by the factory?

Got a pic?

A buddy called me yesterday because his similar bazillion-years-old tiller (Hoffco Lil' Hoe) with a similar engine was running wonky.

I could not find any adjustment screws on it at all.

I fired it up and put a teaspoon of Sea Foam into it .... twenty minutes later it was back to normal.

This one was on the canned True Fuel. It just looked like a normal walbro 40cc saw carb.

Confusing...in the pic above, L screw is on the intake side...which is all I've ever seen on dozens of trimmers.

Yea, never seen this problem in chainsaws so was wondering if anyone else had...

The low side is always the closest to the engine/cylinder.
That one is not??
WTH!

If it's a Mantis try a Zama on there.....C1U-K82. Had good luck with those thus far on Mantis and Echo cultivators.
