That’s what I want to be able to say but I don’t know mechanical stuff like that. It sounds like you’re well versed with it.
Maybe they are both firing but not well. But if you have good fuel, spark and compression, you have a running engine.
I don’t know about the compression part. The gas is fresh non ethanol. It’s a yellowish/ green in the snow only. Could be because it has carbon from the exhaust. I don’t know.
The non firing one I can hold the header pipe the entire time and it doesn’t burn me and doesn’t feel like it’s warming up at all.
If you were lacking compression that extensively, there would be other signs. If you were lacking compression through the valves there would be backfiring. If you were lacking that much compression from the piston somehow, you would hear some clanking.
I guess I’m pulling the fuel pump lid off and gonna suck every ounce out of the tank. Then dry it with a paper towel. How do I get what’s in the lines out? Disconnect at the injectors and blow it out?
That's a good question. I don't know your exact model well enough to give detail.
Yep new spark plugs. I checked the old plugs and they sparked great and the gaps were perfect. Plugs weren’t the issue. It has a new set in it now though.
You may want to check your spark arrester make sure it's not clogged. Maybe even run it for a little bit without it.
What would a clogged spark arrest or do? Would it cause one cylinder not to work?
I doubt it would run at all with a clogged exhaust, but you never know.
Yea with as much fuel that was blowing through it and the blackness on that back I think that cleaned itself. I also think that’s why the spark plug on that not burning cylinder was white when the running side was black. As in the pics below.
One plug looks fouled the other looks like it was washed by fuel. The white is just the porcelain.
Yes exactly. The white is the one washed by fuel with not ignition. That spark plug will knock u on your but from the spark it puts out. I switched them anyways to try it. Knowing that it had spark and the plugs good and the correct gap.
So I guess we have concluded that, with a nice big hot spark, the fuel washed the plug clean?
You have me intrigued now. Enough to take the whole pump out and drain and dry out the whole tank. I just keep going back to why is one firing and the other isnt
@HondaTech do you have any in-site on a P1 with 341 miles on it, one cylinder isn't firing, raw gas coming out of the muffler, sat for 1.5 months without being started, he has new plugs installed and I'm afraid we are sending him down a rabbit hole. Thanks
