Studies in the Adirondack Region of NY show that the wolves still exist but they cross-bred with coyotes. Every single coyote that was tested had both red wolf and grey timberwolf DNA. The nationwide average weight of coyotes is 26#, according to the study. Around here it is common to see them well over 40#. They look more like a German Shepard than Wiley Coyote. Out West they look scrawny and mangey in comparison. They have also adopted some of the wolf-pack hunting techniques and several hikers, joggers and backroad strollers reported being encircled by them and deeply concerned for their own well-being. A friend and native resident of my home town and his wife were "worked" by a pack in broad daylight to the point that they fled to a near-by farmhouse to call for a ride. They felt they were in real danger. Coyotes, by nature are timid animals and rarely hang around in the presence of adult humans and domestic dogs. There may be environmental factors at play too, many housing developments have sprung up in this area. Johnny B. I Mac Therefore I am

I'll check all that when i get there. I will be on the road the next 10 days. Will post what i find when i get a chance. Thanks to all who offered ideas.

Re: [MBZ] OM 603 no start
Yeah, but that was where we started. No black in the prefilter, fed it by gravity from a can through the filter and prefilter. Good fuel flow through the filters and out the main filter. Same behavior ( starts but starves) feeding the engine from the can by gravity. Algae is always my first suspicion. How do you determine for sure if the shut-off valve is good or not? I still plan to try the pressurizing trick, and putting an electric fuel pump between the tank and prefilter.

Have you checked to make sure there's not something blocking the air cleaner? A big blockage there can act a lot like massive fuel starvation on a diesel. BTDT. It might sound far-fetched, but you never know. My dad had a swarm of bees move into the air cleaner of his Fairmont, once. The DNR says they are trying to "grow" the population of deer up to 15 per square mile. They're probably under pressure from hunters who want easy pickings. In Michigan hunting is a big tourism draw and the DNR is always under pressure to keep the herd large. I bet there weren't 15 per square mile back when there were still wolves around.
Re: [MBZ] OM 603 no start
It had not run since bambi put a hole in the radiator in Nov. It started and ran fine after the new radiator and condenser were installed. After they finished charging the AC is when they noticed it didn't want to run more than 1000 rpm, then it got worse until it will now only start and run a couple of seconds, then starves for fuel. I told them to push it to the side and leave it until I can get there to work on it. I think there has to be a simple explanation. Compressor is ok and the linkage is moving freely. It has not been disturbed as far as I know. I will check all that when I get there. The fact that it started and seemed to run fine initially seems to be an argument against the stuck rack theory. I'd like to try Jim's suggestion to pressurize the vacuum shut down and Marshall's suggestion about the crankcase vent. Temporarily sticking an electric fuel pump in the feed line would allow me to check fuel pressure right up to the fuel inlet at the Inj. pump like I used to do with the hand primer. The DNR says they are trying to "grow" the population of deer up to 15 per square mile. In the area where the bambi attack happened, herds of 15-25 in small fields are not unusual. They are WAY over 15 per square mile. More like 15 per quarter of a quarter section (40 acres) Even at half that density, it is 4320 per square mile. I'd like to see the herd thinned to where it was stable, like 30 years ago. Now they are so thick, and so desperate for territory, they are no longer afraid of people, houses etc. They go trotting down the streets of towns and cities. When I lived there, I had 3 bedding in my yard. DNR=morons Loren At 12:01 AM 6/8/2006, you wrote: On Jun 7, 2006, at 9:21 PM, Loren Faeth wrote: > Got a question guys!

Re: [MBZ] OM 603 no start
Nothing changes when it is bottle-fed. (paragraph 1) That was tried with no change. I will try having them start it with the oil filler cap off. Maybe the crankcase breather has gotten plugged up.

If it does the blockade is between the tank and the lift pump. If there is serious crankcase pressure (like when the crank breather is blocked), it will shut off the fuel shutoff valve within seconds after the engine starts.
