| I'm putting new distributor, wires, plugs, etc,... and I know the firing order is 1-3-4-2, but what is the number one piston and so fourth on the engine. Sorry to be so dumb on a small G engine.....but thanks for the help. I have 3 manuals but none actually tell you what the number one piston is.... |

#1 should be opposite the clutch. #4 would be directly next to the flywheel, with number 3 next, then #2, the#1 nest to the radiator ------------- Experience is a fancy name for past mistakes.

#1 is at the front of the engine(always ?) ,but since the engine is mounted 'backawards', it's the one nearest the rad/fan.
You're right 3 books here too, NO picture of who's first !!

Number one is at the crankshaft pulley. That would be to the rear of the tractor on a G.

Don and Jay are only partway right which could mess you up. The engine is in backwards. The number 1 cylinder is at the back of the tractor. The radiator and fan are above the clutch and flywheel which is on the rear of the engine block next to number 4 cylinder. Now that should be clear as mud.

| And if you think about it for a while it doesn't matter which cylinder you call number one, the end result is the same. 1-2-4-3 from the radiator back becomes 4-3-1-2 from the clutch forward. So if you look at those numbers you can see that the firing order doesn't change. The only thing that is important is that when it is time for a given cylinder to fire the rotor is supplying spark to THAT cylinder. |

| True but it can become very confusing when you do not have the principals rock solid in your head. A person need not know the firing order in advance if they know how an engine operates. One only has to check for the compression strokes and watch the valves close and mark it down. You could then call any one of the plugs number one but would not have a standard reference point to discuss problems with others. |

My point exactly Dick, I could have worded it better.

Which ever one the rotor is pointing to when number 1 is at TDC of the compression stroke. It can be any of the 4 holes, depending on how the distributor was installed. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Turn the engine over until #1 piston is at the top of it's compression stroke. Then the post that rotor is pointing to is #1. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |
