The linkage from carb to lever needs to be right distance. Some manuals explain some on the procedure. My Dad usually does this for us by bending the lever one way or another. To far one way it will surge like an oliver to far another it will be a super dog or no acceleration at all under a sudden load. Allis was legendary on the snappiness of there gov. just wish it was built a little heavier. Our D17 grenaded the gov. at 2400rpm then went on to ruin the gov gear and crank gear. I have heard of several others breaking the weights off.

I always go by the book on syncronizing the governor. Use an Allis manual cause the I&T manuals gets it backwards. It makes a difference.

The main reason that a WD-45 governer acts different than the D-17 is simple. It is SPRING RATE and the tension on the spring to start with. Put a WD-45 spring in the D-17. Set it to rated WD-45 RPM and see how the engine responds.
It is not the crankshaft weight or the the .36 ft/lb change in rolling torque on the main berrings. That is a verry small percentage of a single horse power at rated speed.

I don't believe that's it. I've had engines where I've put different springs. I never put a 45 spring in a D17 but have put a 45 governor complete on a 45 with a D17 engine. I still say it's the weight difference in crank and probably flywheel although a 17 engine in a 45 with a 45 flywheel make no difference. The 45 engines has more snap.

for the pullers out there at a compression ratio of 11.1 static 10.5 effective intake closing at 86 degrees 150 cfm. the 2.475 main bearing at 3000 rpms has 18.73 ftlbs of drag the 3 inch bearing has 20.18

The other day rod b made a comment on lowering rod journal size. Still playing with engine bearing friction droping 3/8 in the rod journal reduces a full 2 lbs off engines total friction. I guess them nascar boys are on to something when they go to the 1.88 rod journal

You mean bottle rocket scientist.
I was picking on the class clown about narrowing the rods in his engine build. A narrow crankpin is stronger than a wide one, and if it matters the narrow berring has less drag.

Rod b the proper name is crank fillet radius. Some just know enough to aggitate . Narrowing rod without knowing the crank fillet radius is just loosing oil pressure unless your opening up the clearance to use a bent rod. Everything one chooses to do engine wise comes with gains and losses. Getting the most gain for the least drawbacks is when you start challenging material composition

Heck , Lou, I 'll answer your question. You may live in an area where machine shops are all doing hi quality, no compromise work. And those prices are probably not out of line for an established shop with well qualified machinists, using the most accurate machines and tooling available. You may not require that level of work for your application, my advice.... shop around, there is ALWAYS some one who WILL do any job CHEAPER.
PS you really do know how to bring out the best of the peanut gallery ! And I think they should throw in an align bore,recondition the rods, complete balance job, and all the head work, too. LOL
