Need info on fake 372's (Holzfforma)

[Sawdust Man]

Looking for input on these 372 clones, I've got a couple that start up fine, and idle but then they bog and won't cut nothin', one has about 1/2 tank through it, the other maybe 2 full tanks.
I tried searching here and google, but no luck... I'm sure I've read about these issues here or on the "other" site, but now I can't for the life of me find it.

Are they tuned too rich? I hear the carbs don’t hold a tune….

 

[Sawdust Man]

Possibly, but I've tried lots of adjustments with no cure so far.

The fuel pump cover on my original carb was stripped out, making tuning impossibly difficult.
Pull your plug to see if its choking out after it boggs down.

One of mine the carb spring was too stiff and would hardly start and run or rev up.
So I swapped the carb spring for a oem spring out of a old carb that was the same length
Cured it that was four year's ago.

Ok, that's a starting point.
Thanks guys!

The ignition coils timing is crap. Try a new oem coil if somebody has one you can borrow.
