I apologize for what I am sure is a dumb question, but what is the # 1 cylinder in a straight 6 gas engine ? I want to say it is the "hole" closest to the radiator? In the process of a tuneup and we want to throw a timing light on it while we have a "guy" helping. His expertise is I/H and is 99% sure I am correct but I just want to verify. We have an OP manual and an IT brand service manual,so i "assume" between the 2 we should have the timing specs? Any input would be greatly appreciated. Thanks.

Correct! #1 is always at the front of the engine.

Now that I think about it...the G Allis tends to trip people up sometimes since the engine is in backward.

Not all are the one closest to the front. I know the deutz are numbered from flywheel and I think e g is too. Not positive on the g though

Timing should be in the op manual. IT manual skips most common stuff and isn't worth the scrap paper its printed on. Look for a real shop manual it will be as much a 200 times as thick. http://www.grandpastractor.com" rel="nofollow - http://www.grandpastractor.com
is a good place to look.
