I bought a C-71 in Apr.2018 & it's been sitting ever since I bought it.The HL carb intimidated me for a while,but now that I've got 2 rebuilt I feel more confident to tackle this one.The saw has a Tillotson 141C carb on it.The only difference I can see between the 141B & 141C is the fuel inlet is on the opposite side,& Tillotson decided to put a cover on the air intake side of the carb .The saw has great compression & the last I knew it had spark.I'll rebuild the carb tomorrow & see what happens.When I bought the saw I got a rebuild kit with it.I went through the kit tonight & was surprised at the age of it.I got gaskets galore & it contained a new metering spring,it also has the old style needle & metering lever (the lever doesn't hook onto the needle).

I rebuilt the carb yesterday & noticed that the metering diaphragm & gasket were in the reverse order while in the carb,plus the needle was black & stuck in the seat.When I reassembled the carb,I put the metering diaphragm & gasket back in in the "correct" order according to the IPL.I put the carb back in the saw & put on a new fuel filter & pulled & pulled.It won't draw fuel.I'll pull the carb back off again & pull it apart again & reverse the diaphragm & gasket & see if it makes a difference.Otherwise I'm stumped.

Well folks,it's a runner! I took the carb back off & reversed the metering diaphragm & gasket & put it back on the saw.Within 6 -7 pulls it was running,a little too much on the rich side.I had to screw the idle screw all the way in & the lo needle is set at 1/2 turn out from seating & the hi needle is set ast 3/4 turn out from seating.That was the only way the saw would idle & run properly.I took it over to a 2 ft.in diameter oak log & it went through it like a hot knife through butter.A bit of a heavy saw to operate,but man that beast has power!

I really enjoy the C series. They're kinda heavy and slow but they do have a lot of power. Sound nice too! The C-71 is the only one of the direct drive C series that I don't have. One will find me some day... Congrats on the runner Ed! Enjoy

I had the C-71 out earlier today doing some noodling on some fairly big oak logs.The logs are so heavy that if they're not halved or quartered they'll flip my splitter.That saw truly amazes me at how it slices through those logs! I had to do some fine tuning on the saw,it was way too lean & I didn't want to burn up that saw.The lo & hi needed to be turned out about 1/4 turn ea.Now the saw runs great! I wish I could show the saw cutting to the guy who sold it to me last yr.He'd probably kick himself.Lol
