With an assflap for good measure

Hey Pal, thanks for triggering an old, long-burried memory from Bad Christmases past.

....... wanna hear it? I know you do! ;)

So anyhow, it was about 2 weeks before Christmas and Me (8) and my sister were spending the weekend at our beloved Nany's house.

Naturally we started wondering what we were gonna get and where it was hidden.

We immediately found the presents under the couch near where we were playing. Some really nice stuff!

............. so Christmas day rolls around and after Church we unwrap our presents.

...................... We each got two pairs of knee-length underwear with the back flap, the kind of underwear that NO self-respecting child had ever worn since 1935!!!! :shucks:

Recently perusing the nets with an image search, as a standard search query wasn't turning out the item
I am searching for.
My pup has no hair on the back of her little legs and all I wanted was to find some winter "pants" for her so
winter walks will be pleasurable for her and to reduce the amount of blocks the mom (me lol) ends up carrying
her cuz she's cold.

This is an image for an advert for "dog training pants". While not what I was looking for as I quickly scanned
the images.... IT popped right out at me.

Maybe I'm twisted but... I KNOW at first glance... what I thought I saw lol.

A bit over a foot of snow in the last couple days or so, and more on the way. Blowing about 8-14 inches of heavy snow took more time and energy than it used to; springs that adjust ride--height on the blower are weak, and replacements are on the way. Until then, it's a constant struggle of having the transport bar pop out of the hardpack setting.

Caribou hunt up the Steese Hwy was put off for the heavy snowfall, and for my larger freighting snowmobile needing to get on an engine analyzer this evening. Seems it's burning really lean in the forward cylinder, and rich in the rear cylinder, soiling the rear plug, while the forward plug is obviously burning hot and white; something I've not seen with this V-800 motor in the past. And initially stumbling on one cylinder when first started, if it's been sitting a while.

Tested the injectors and the fuel pressure, and both appear fine, then hooked up a fuel pressure instrument, taping it to the handlebars, riding for a while, closer to town, to see if there was any fluctuation in fuel pressure. Nope. Nada. None was evident, anyway

So, following the date tonight with the engine analyzer, I may be looking at an obscenely expensive CDI/ECU/Electronic Box for the thing. That'll make this some pricey caribou, if we pull it off.

If it needs the computer, hopefully it gets here by early next week (doubtful), as the temperatures and precipitation forecast for next Tuesday AM through Wednesday PM looks to be inviting, if we needed to spend the night there on a hunt, sleeping in the back of the truck.

Not sure at this time if my younger son is still going. He's gone back and forth on it several times; the angst and combative nature of being a late adolescent and getting ready to launch; in that uncomfortable place of having your view of your father shift over time, even if only temporarily, from hero to sometimes-asshole... just add water, a couple more birthdays, a few terse words, and stir gently.

If I'd have known parenting would involve this much heartache, especially that brought by his 2 notably older siblings, I'd have changed course on the whole Waltons and Little House on the Prairie, meets Norman Rockwell prints in my mind's eye, and burned those images more properly in a wood stove... like, decades ago.

'Tis OK, though. When life attempts to piss in your eye, it can be mildly helped by eating good, decadent food. So, tomorrow night, Christmas Eve, premeditatedly cheating on the vegan anti-cancer diet, I'm partially cooking some slow-cured bacon, then wrapping some sea scallops in the bacon strips, and broiling until golden brown and safe re. pork temps. Some stir-fried veggies and maybe some quinoa will make that the evening's dinner.

Merry Christmas.... Ho, Ho, Ho.

Presuming the v800 is the petrol one, the fuel pressure should probably track inlet manifold pressure. If the pressure is steady, it could be a FPR failure. Suggesting the fuel rail starts at the black plugged cylinder

The 2 machines I have here are both gasoline combustion engines. One is a 2-stroke, for which we mix 2-stroke oil with the fuel on a 40:1 ratio. The nearly 800-lb. freighter beast is a 4-stroke, so no mixing of 2-stroke oil with the fuel, but unlike the 2-stroke, it has crank case motor oil, whereas the 2-stroke is lubricated via the oil in the fuel when the pistons operate during combustion.

The fuel pressure regulator might be an issue. I'll have to check to see where that is. Burt earlier, when it was run around for a while, trying to give it an opportunity to 'act out', the fuel pressure gauge seemed to indicate the pressure was fine. But we'll take another look tomorrow.

The machine in question didn't make its trip to the second analyzer it was originally scheduled to be at this evening. I got 'back-burnered' again. I'm now told it'll get a read-out on the machine tomorrow.

We'll see.

I'm fairly certain it's either the wiring harness (possible oil contamination in the harness plugs/connectors beneath the air intake box) or the CDI/ECU/ECM/Electronic Box.

The harness would be a pain in the ass if we have to fabricate one and make the original plugs in the harness work properly, rather than running a bunch of jury-rigged connectors. But it would be a BUNCH cheaper to do the harness (I think) than that $1,160.00 (retail) ECM.

I think 'Murphy' has some sort of weird crush on me. 'He' keeps screwing up my plans. I think he's seeking attention.

The FPR will probably be right at the pump, and have a vacuum hose coming from it to the air inlet manifold/tract.
The general idea is to keep the fuel pressure at the injectors around 43psi above inlet manifold pressure. So the fuel pressure gauge should be showing near 43 at full throttle but maybe just a few psi at tickover. If you have no change in pressure as you open and close the throttle, be sure to look up the FPR as a part for your engine. I feel sure there is one, as running without would be highly irregular.

As you just have two injectors, the fuel rail is probably just a couple of equal length pipes to a T piece. This would make the difference in fueling a little hard to explain. Though that pressure really must track inlet air pressure, so if it's not doing, you could look if the vacuum hose is split or the FPR dirty. 30$ item if it's broke.

I'm not sure what 1200$ CN is, but it sounds a lot. It's very unlikely though. You might loose an injector to a faulty ecu but one up and one down is in-explainable. It just does duty cycle and has no logical reason to treat both injectors so differently.

Of course, the amount of fuel isn't the only reason for unequal burn. The amount of air should also be considered. This appears to be a 4 valve per cylinder engine on a single camshaft, but maybe a rocker has broke. If the air passing through is restricted, the exhaust will be rich. The ecu doesn't know why, as it's a combination of both cylinders. It will reduce fueling to see the reading come back in range. Leaving the good cylinder lean, and the bad one rich. A look down the plughole as you turn it by hand could let you see the valves? Or an endoscope is like 10$ these days. Often called a borescope now cheap enough for such use. It's not twin throttle bodies is it? That would be a bit trick, but another reason for uneven burn.

This sniffing of the exhaust to look at the combined output of both cylinders can cause issue for both quite often. Say one injector was a bit blocked. The overall lean condition would lead to the ecu increasing fuel to both. At some point, one is a bit lean, and one a bit rich, and it's happy seeing the average. That sensor is usually ignored during warmup on a single wire version, but 3 and 4 wire sensors warm themselves so rapidly come online. This info can help with how it looks when starting.

We'll see what the analyzer has to say later today, and go from there, assessing how bankrupt this venture will make me.

Both injectors had good pressure and good spray pattern.

I figure it's Murphy's way of telling me to postpone the caribou trip again.

In other news: Star Trek Discovery sucks.
There is only one straight male, who's job is to hold the captains hand and stroke her hair. Or talk about his feelings.
The only person likely to ever slap some ass was Tilly, who's been 'dropped off' presumably for having some character.
The last away mission was all female.
There is a bridge extra with a head as big as a beach ball, who somehow got a T-shirt on.
They have transferred a transsexual into a new body and put them in a girl/girl relationship.
I have tried to like it, but the cast interaction makes it only for females. Something the original was never about.
