You probably wrote this before getting to the last post, the issue was fixed by swapping the ignition coils, with the right one being clearly bad....
Engine would have been broken in on OEM Deere dino oil. It's a 2007, and original owner did none of his own maintenance, but just had local Deere...
BTW, the one unresolved issue is positive crankcase pressure. The result of this is that any small leak in any seal causes the engine to blow oil...
Well, it was not running on one cylinder previously, at least in any fashion continuous enough to detect, I’d checked previously several times...
New fuel pickup tube installed. but still exhibiting the same problems, so that wasn't it. The old one was soft, and did have a bit of a kink in...
Yep. Sorry, I should have been more clear. I have no problem using dino or full synthetic, although I usually stick to Deere OEM fluids for...
Thought about it, but there are big warnings all over service manual stating "DO NOT TEST THESE COILS WITH MULTIMETER OR STANDARD OHMMETER....
Maybe. But it was leaking before using any synthetic, on the OEM Deere 10W-30 Turf, dino formula. I only added synthetic because oil was low...
Oh, one other thing. I mixed synthetic and dino oil in this machine, just before it got really belligerent. It was leaking oil out the front...
Thanks, MM! I had that line fished out of the tank last weekend, and it looks/feels good, but it couldn't hurt to replace it. I'll have to see...
Yes. I had one car that had a bad coil that would just cut out randomly. Took me forever to diagnose that one. But even more to the point, I'm...
Exactly as I suspected. And since I'm already meeting fuel delivery rate spec just cold-cranking, this would seem to rule out fuel delivery problems.
I've been thinking more on this overnight, and I guess it must come down to whether an impulse pump really cares whether it's getting vacuum...
The issue only acts up after some time, sometimes not for a few hours, other times after just 30 minutes. But I'm not going to bounce around my...
These are magneto coils gapped .012” off the flywheel, so while I do have quite a few automotive ignition coils laying around, only the OEM or...
Two coils, with one hardwired spark plug wire on each. It's actually a pretty nice and simple setup, but I'm willing to bet those coils are...
It’s still misbehaving, albeit very intermittently. Think it’s time to buy new coils? Both header tubes are hot, but I’d expect that until one...
It definitely could explain why it was so bad before rebuild. But everything is sparkly-clean now, and it's still doing it just a little, albeit...
I suspect that if the fuel is boiling, it's happening in the carb bowl itself. But unlike my good old Holly 650's, this one only has a single...
Impulse. Basically mechanical, which operates off air pressure or vacuum ported off one of the valve covers. This is one of the reasons I was...
