| Unless you are planning on taking the engine apart and replacing pistons/sleeves and camshaft or changing the crankshaft to a longer stroke, the only thing you can do from the outside is install a larger carburetor and maybe increase the RPM's of the engine. That's it. The engine was designed to produce 43 HP at the PTO at 1400 loaded RPM's. That's all it will produce with a good tune-up. There's no amount of tuning you can do to change the results. Too many people think you can do a super-dooper tune-up or add some magic spark plugs and instantly gain 10 more HP.....it just ain't so. |

| There are a dozen ways to increase compression and cubic inches up to 400 plus cubes. It all depends on if you want to spend $1,000 or $5,000. |

| Genuine AGCO new piston and sleeve kit for an AC 175 gas tractor ( set ignition timing at 23 degrees BTDC at WOT).....$1,000.......regrind your camshaft to a 175 profile..$300......175 venturi in the carb..$40.....Pertronix pointless ignition...$125.....D-17 governor spring....$???.....total of less than $1500 and will make nearly 20 more HP at 1800 loaded RPM than your engine will at 1400 RPM and you can still use it to farm with on regular gas. |

| If you can find A SP46 M&W kit, for wd or wc . Machine .250 off the tops of the pistons, that will give you about 10.25 : 1 compression. You will have to use high octane gas. But this will do the job. GOOD LUCK |

Are you talking high octane (Super) regular pump gas or racing fuel? |

Racing gas will work the best, but if the timing is retarded A little, the highest octane pump gas can be used. Just don't let it ping, that loses power & can damage the engine. GOOD LUCK |

| You can't just dump E-85 in the gas tank and expect an increase in HP. It would require re-jetting the carb just to run correctly and even at that, I doubt you'd see any HP gain. A dyno is the only way to know for sure and just running E-85 with no other changes will net less HP I'd guess. |

| e 85 does make more power with high compression I couldn't get mine to run near as good with high octane race fuel at 8 a gallon u do have to drill the jets out |
