We had our first Test pull yesterday and I was real happy with how my D17 performed with the changes I made over the winter. Electronic ignition WC flat top pistons and sleeves (I have 210-220 cylinder PSI now) 170 venturi Concrete spun rear tires for sharpness Seat of the pants: The exhaust note has changed for sure, much more crack to it. Definitely has more oomph to it, wish I could find a dyno locally to check it. Tires did bite better but I want to go to 38's in the future ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

| I think you mean a "175" carb venturi, not a 170. |

| I remember a fellow that use to post a lot on here saying the all is 226 liked more carburation and you would know it by the exhaust note the it was a step in the right direction |

I guess I could borrow a D19 carb and see if it would work...I think the linkage is backwards.... Or some other brand. I think a Ford 901 used a bigger carb that would work?? But I need to keep it stockish....since it is not strictly a pulling tractor ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

That same guy also posted: that he ran alcohol for fuel- I'd like to know where that he owned and operated a Gleason automatic crank welder- which is a lie that an off-set bushing gives same degrees no matter how far from center-line- Which defies math, geometry and logic And that he employed half the county in his machine shop which is also a lie Why would anyone trust his word about a carburetor?  Just asking |

| Once again Butch's jealousy of Pankey has reared its ugly head.Butch I've seen Pankey bolt can gear on take to drill press drill and drill it then open up the bolts holes so that bushing will advance or retard camshaft install it in 226 engine and it degree exactly what the bushing is . I guess he is just that good. |

For me one of the most fun things in life is to call out the wannabes, farses, and pure liars and have them prove my point all by their lonesome, Thanks Pank  |

| If the girfriends are done with their catfight! Charlie: Now that you have made a lot of improvement, how about coming to the pull at Frederick May 3rd? |

Butch if you have noticed these post get hijacked by the likes of you LET IT GO most have lost all respect for panky mg is steady losing respect for standingup for him and your going down fast for just playing the game as paul said charlie dont stop we want to here what you've done ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |

Our local club pull is the 3rd. Plus I think your CA will out pull my 17!  I was thinking about getting another set of governor weights and removing some of the mass to get some more spin (Or does someone sell them this way?). The power curve should go up, but yes I understand I would still have the same power at my current RPM (1950). If I spin up to 2200, I can theoretically gain how much HP? Does anyone have a chart? One guy says his revs to 3000 but I am afraid to go that far! As you can tell I take small steps.... ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

Ya know, you are right on the first count. I dang near erased those posts and probably should have. I can take due criticism. As for status? I am not here to impress anyone or collect brownie points. The site has the privilege of throwing me off anytime it feels the need for the improvement.

Geometry boys and girls, geometry. Numbers don't lie but liars make numbers. The Chverolet based offset bushings are made to work on a certain distance from center, or on a certain radius. It's probably about .700" roughly going from memory is the distance from center of camshaft or the axis, to the center of the bushing. You can't install the bushing on the Allis this close, the cam is hollow and there is a plug...... Anyways you could make a 4 degree bushing move the cam say 2 degrees by positioning it double the distance from center. Now if I dumb it down for pankey, if you look at a clock that is 8" in diameter the minute marks are closer than a clock that is 24" in diameter...... If you machine an offset key for some applications you have to take the shaft diameter into account in the formula, same goes for a cam bushing. I know I'm wasteing my time dealing with someone who will simply lie, or simply lacks the capacity to understand basic geometry much less something slightly more advanced. ------------- "see what happens when you have no practical experience doing something...... you end up playing with calculators and looking stupid on the internet" |

| im running a marvel carb off a 230 gas motor on my 241 and it still lugs pretty good you have to swap throttle shaft around. I think a 19 carb would be a little too big. |

| When I redid our D-19 Gas a couple years ago I bought a complete rebuilt M/S carburetor for less than $200 shipped, no core. Probably a bit higher now. |

| You'll have to remanufacture the throttle shaft lever and turn it around to the other side of the carb, but it's worth the extra effort. Make sure your new lever is exactly the same length as the old lever (c to c on the holes) and positioned/clocked correctly. Then, be sure to synch the governor arm to the carb when done. |

| Butch the way Pankey explains it is that he isn't machining a offset key in a shaft . He is drilling a hole into the cam gear and can for a pin and a degree bishing . the timing gear and bolts are already index so when you drill for the pin the pin is indexed as well. Then you slot the gear bolt holes and use the degree bushing . Pankey has a Facebook page all is WC& WD pulling engines if you need to discuss with him |
