A stock E gleaner engine isn't going to pull well against non stock engines but you can listen to the others or you can take some money and go to the horsepower store and get you some stroke and 12.1 compression cam lift around .550 on the intake work the intake ports and be more close to what your going to be competing against. I an Ed were talking to Ronnie another engine shop owner race engine design a couple of weeks ago about our 440 cubic inch allis project for a client . Ronnie couldnt believe the machine work or money that goes into one of theses antique pulling engines . Its easy to tie up 10 grand in one and 14 grand will get you a 430ci sb2 turn key. but thats a different class of pulling and sb2 engines dont make the torque so 12 grand will get you into a 14 or 13 degree that will make torque and win pulling in the v8 classes. jmho

| Run a compression test with all the spark plugs removed, throttle wide open and a battery charger on the battery. I don't care WHAT the compression is, it just needs to be the same between cylinders. Timing is adjusted to F-25 or FIRE mark on the flywheel with engine running wide open throttle. If your flywheel is a WC-WD-WD45 the FIRE mark is really F-30 which is too much.....back it off a bit to F-25 degrees. Your post is simply so vague on what's going on, it's very hard to help, other than verify good compression and proper timing. What have you changed since the last time it ran good ???????????????????......Bigger rear tires maybe?? Valve tappets adjusted to .015" COLD on intake and exhaust. |

doc it appears that bmartin55 is where cotncrazy was a year or so ago . So my advice to bmartin55 is to do a search on cotncrazy's post he is good about posting what he has tried and what seams to work for him . He even posted what he settled his valve lash in on for intake and exhaust if I remember correctly.

| Where exactly are those marks on the flywheel? And how do you check the timing with them being on the flywheel? Is that a dumb question haha |

| Correct, yes. If this is a WC-WD-WD45 that mark is 30 degrees BTDC. If you have a Gleaner combine engine (more compression) the timing needs to be at 25 degrees BTDC, so if you didn't make a new mark on the flywheel before installation of the engine, you need to now while in chassis. Not too hard to determine 5 degrees when you look at the TDC mark and the Fire mark being a total of 30 degrees. |

| Quit using better gas than it needs !!!!!!!!!!!!!!!!!!!!!!! it won't make any more HP and probably LESS HP with 92 octane versus 87 octane. |

| Sounds to me like you've had an ignition problem with "wet" spark plugs. Fresh air intake above the hood is better unless you have a poorly designed pipe connecting to the carb (like a pipe with a "kink" in the bend instead of a smooth mandrel bend) or your exhaust pipe is too short allowing fumes to be pulled into the intake. Gas use with stock compression needs to be 87 to 89 octane and no more. |
