I need a bit of help on the oiler.

This saw has the pro oiler, but the stop on the adjustment screw is broken, so it jus turns.

It's not oiling so well. Very stingy. I have the screw slot perpendicular to the saw body right now.

Can anyone here tell me the proper slot direction for max oiling?

Al, I'm pretty sure there is a roll pin that holds the adjuster screw in the pump. Also pretty sure the same pin acts as the limit stop.

Richened her up. Think it's better now.

I guess the other problem Al, is that you could be 180° off with the screw. Possibly, one way it won't oil at all, the other it'll work correctly

Who's gonna set up an official Go Fund Me account for a cant stand for drf255? He could sure use one lol

Cfb's 026 is a brute.

 

[Backtroller]

Yeah that cbf 026 is awesome. It really likes that 044 carb. Blows my mind that it can use all of that fuel.

And uses fuel it does.

You didn't set out to build yourself a Prius in this endeavor. Plenty of boring saws floating around already

Man.....you guys have dropped a boat load of knowledge and ideas on this thread since the initial question. Very cool of you all.

Just thought some may like to see how I open up a filter for the 026 or MS260, the first pict shows the stock choke flap position and the stock opening for the carb to breathe through, I ouylined the opening with a black marker to show what I remove to change it from a 0.700 opening up to a 0.750. This may not sound like much but it really moves a lot more air through it.

The filter below shows how much the choke flap sits back from a stock one , the opening for the air to enter the carb has been enlarged by 0.050

The filter housing below marked with black marker is where I grind out some nylon material to let the choke flap sit further back from the carb opening,

The filter housing below is ground out for the flap to sit further back in,

This pict outlined in black shows where I remove some of the baffle to allow air to move more freely from the upper filter area down to the carb mouth, Actually I remove the same amount on both halves of the filter,

This is a filter with the baffle ends removed, this allows a lot more air to get to the carb unimpeded,

Looks like your mods may eliminate the choke being pulled shut on these saws too!

The choke flap sits back /opens 0.525 on a stock filter and after I grind away the area I show in the pict the flap sets back 0.700 so an increase of 0.175 and the spring still has plenty of pressure to keep the flap retracted, also having the flap further back would allow more air to pass creating less vacuum or pull on the flap making it less likely to be pulled shut by a high revving engine.

That's what I was thinking. Sometimes it doesn't take much!
