What is the best way to get max rpm and max advance on stock 226 without a dyno for a puller

Set the timing at 30 degrees before TDC at 2000 rpm. You want maximum RPM's ?? Tie a rope on the governor arm and pull on it.....been there, done that. I get a strange feeling you think you can magically "adjust" the ignition timing to gain HP....you can't and that's the end of the story.

And yes you can get a horsepower increase with timing and jet changes in the carb(not a lot but a lil)---but that was not my question and thank you for your input it is greatly appreciated.

And No, you won't gain any HP ( more than factory rated) on a D17 gas engine by changing the timing from the stock settings when you are working with a stock engine/compression/camshaft/carb/ RPM range.

Dr. Allis you are correct . That what I was asking how to get the rated or max rpm and h.p. available. If the timing and such are not set correctly your max h.p rating will not be met . You said to set at 30degrees btdc. Ok now where do I shoot my timing light fro the marks . I do not have a manual yet and just purchased this tractor for pulling and just need a lil info . Thx

I have always heard 28 to 30 degrees timing . I have no dog to race about power from timming either . I will say that I have tried 28 and 30 degrees timing at 2000 but I always go on up to 36 to 38 total timming( all advance in )on my puller but everyones engines are different . Octane of fuel heat range of plugs , has as much effect on the amount of timing you can run as anything else i can think of.

You better believe that if changing the timing to get more HP would work it would have been done at the factory. When the D 17 was new the competition with other companys at the time would have caused them to change it. When you are talking stock engines that is.

It seems funny to me how people hear what has been done to an altered engines think that those things will work on an unaltered engine.

Pulling somewhat stock engines for ten years I have tweeked every thing I could try and found until you change the stroke, piston size, cam shaft grind and head all the other so called HP improvements just don't work. The most HP on a (stock) gas engine can be achived with a proper overhaul and tune up. Trying to up HP on a tired engine has its own pit falls.

you looking for more hp on stock engine ? It comes in a gallon can at 40 bucks a gallon . unless you can hide( sneaky pete) easy then 50 extra hp. comes for around 300 bucks

On A stock Oliver 77 I tries 92 octain and some different racing fuels and the old girl did better on plain od regular gas.

I most always loaded three tractors and would bet in ten years I didn't come home without having one in the top three more than a dozen times if that. Most of the time more than one if not all three.

ok . i remember when i was back in high school and looking thru hot-rod books seeing cars with nitrous-oxide. i have been wondering about added and used on a 226.. i would think it would be hard to hide the bottle plus the instant extra hps;-)

If anyone can make 100 plus hp out of a 226 cubic inch motor with no cam and cubic inch change, no power adders such as turbo ,blower , nitrous, or nitro fuels. I would like to see it and talk to them. I gaurantee it would cost more than 300 dollars in up grades to .
