Holzfformer G372XP

The hose must have been kinked or blocked, thanks for the suggestion. I pulled the hose up into airbox.and blew through it to check it was clear, then it started ok.

One problem was the original felling dogs were made of cheese, and came with a spare oversized comedy dogs that reduce the usable length of the bar. I used O1 tool steel and cut some new dogs mostly a copy of the original shape but slightly longer.

The 52mm big bore kit has arrived.

I dont really know what to look for in the cylinder, so I got a load of photos to show you. Looks good to me. Couple of lumps at the top of combustion chamber but above the piston.

I have started on this, well stripping the old cyl off, I would value any input as I am new to 2 strokes. Also note having just fixed a tank issue she has had a lot of starting attempts recently and not done any real work or warmed up for couple weeks - may explain the carbon?

Nice to see well oiled for a 50:1 mix.

The light vertical scoring can not be felt by fingernail and I believe was there from new. Glazing/burning in the last pic?

Roof of cyl has some tiny marks, a sign of debris getting in, or running lean?

 

Thanks for reading.

It’s not just China bashing.

If they produced a brand new design, with innovative features, and put it out at that price (or any price in fact) I’d be interested.

But they steal decades of research and work of other companies, by just copying.

 

I don’t really care that much you understand, buy what you like.

and where would we all be if they didn't ? if they didnt make the bigger companies up grade and improve ? if they didnt make others think ok we gotta do better?  I know i like my new 562 in comparison to my B&Q special .

It’s a fair point.

But do you think the constant improvements in professional grade saws are due to competition from supermarket saws? 
 

Unlikely imo.

why would you think unlikely ? if husky bring out a new idea how long do you think it will take till  you see Mr yingchung   using it to make his budget special better ? not long . so that keeps the improvements coming which in my eyes is a good thing .

Granted you can use the argument for all industries including cars, tractors and microchips.

 

Whilst not necessarily knock offs, they sell the die and manufacturing equipment to the competition in say Japan and china for a tidy sum once it's say 5 years behind your current product.

 

Everyone benefits, whilst you're loyal customer base buys the newer and usually better products.

 

The special sauce is usually how it's machined and metallurgy rather than just a patent

The supermarket saws and the Holzfformer are different arguments.
