Oiling problem - Komatsu / Zenoah

[cheshire cat]

Think it was just turned up too far.

 

how is it adjusted? while only pumping oil at full revs I changed the "screw" in the breather for a fuel filter and it floods out -- starting to wonder if plastic worm drives give up because of high oil tank vac:confused1: back to the drawing board:001_smile:

that's interestin' I assume you mean chain sprocket the larger 44cc (rarer model) has a 7 tooth drive sprocket but the worm is the same p't no

 

No, the worm is different because the Ryobi will only mate up with a six tooth sprocket and the Komatsu with a seven.

I'll have to take some pictures.

There's a screw underneath. I'll add it to the photo list.

The one on the left is the Ryobi one that Cheshire Cat sent me.

 

 

 

 

As you can see, they're the same shape & size, the only difference is the number of teeth which makes them incompatible.

Suggestion - get a dremmel, grind out one of the two location teeth on the Ryobi one and fit:thumbup: or am I missing something:confused1:
