You need to determine the part number. Any model numbers on a tag on the saw?

Here is where to find the part# of the saw in the title.

I just got a D 47 H saw that runs quite well after tuning the L jet. H jet seems to be a fixed jet. 16 inch bar with 1/2 inch chain. Is this still a Roper engine? Mike A list says it is a AH-47 engine. Area they the same? 917.62805 is sears model number. Has 110 PSI compression warm. Cannot figure out how the sharpner works, think some part are missing. Does anyone have any info on it?

917.351050 uses the Tecumseh AH440 engine. The engine type should be #1497.

Bore = 2.09" , Stroke = 1.25", Displacement in cu." = 4.30

There is usually an aluminum tag secured underneath one of the crank case cover bolts. They are pretty flimsy & not what you consider when you think of a "normal" ID plate that is riveted into place. This tag is the key to properly identifying the engine assembly. Power Products/Tecumseh made a huge number of engines for a large number of saw manufacturers during the heyday of the chain saw. They basically made 2 different engine types. They made split crankcase engines (AHXX) and then they made unit block engines (AHXXX). Your Sears saw is of the later type.

The carburetor is a Tecumseh diaphragm model. Diaphragms & needle & seats are readily available since Tecumseh basically used these same parts, as far as I have seen, on all of their own 2-cycle engine carbs.

The infamous Roper clutch shoes are indeed very delicate. I have a Sears 3.7 Ranger saw that the previous owner broke several of the shoes in an attempt to replace the drive rim. They are hard to find. I also have the same model of D-44 that Guido Salvage posted a pic of. The engine type on mine is #1521, also an AH440 variant. It would be interesting to see if a clutch & drum assembly from a different manufacturer would fit.

You might try Sears parts . com and enter your model #, & see if anything pops up. Don't expect to find those clutch shoes.

do you know where I can get a coil for a direct drive mid 60's sears D 49

I know this is a very old thread but just for fun thought I'd post something here.

Looking through some stuff and see I have the Assembly and operating instructions for a Sears Model Np. 917.351040 and 917.351050 and also the Parts book for those models.

If these would be of any interest to someone let me know.
