Seems I have no end to troubles with engines. Today's issue is the 126 gas in my 955 swather. Been having issues for a while, it seems to get rich and eventually flood out. Gets worse the longer it runs. Been getting worse over 3 years time, but it only gets maybe 10 hours a year of use. Originally I thought since it gets worse with use it could be the coil or condenser, so both got replaced with a complete tune up including copper wires, cap, rotor and points. I got no change. Took the carb off and found nothing wrong there. I have good fuel flow and the original mechanical pump works fine. Bought a rebuilt carb and got no change. Since it's running rich I tried shutting off the fuel and letting it run dry thinking that when it ran out it would clear up just before it shut down, but it just ran poor til it died. Switched out the coil and condenser from my DC too confirm they were good and got no change. Put the coil and condenser from this engine in the DC and it runs great. Put another new cap, rotor and plugs in and got no change. Battery shows 12.6v sitting and 13.6v while running. Key switch was replaced last year. I haven't done a compression test yet, ordered a kit today, but I don't think that's an issue. This is a low hour engine and there is little blowby. If it had gotten dusted there should be a lot of blowby. I can see the valves through the spark plug holes and they look fine and are moving. This is not a miss on a single cylinder or two anyway. It runs but spits and sputters and back fires out the exhaust when it loads up.

Today's Featured Article - Recollections of a John Deere GP - by Charlie Cook. I grew up on my dad's 280 acre general farm in Western Michigan. Dad's only tractor when I was very young was the old GP. My first recollection of this tractor was when dad allowed my brother and myself to ride on the tractor with him driving. One of us would sit on the left fender (away from the clutch) and other would sit on the gas tank and hold onto the crankcase breather pipe.
