Decompression doing anything?

As a side note the placement of that thing is a really poor design decision. It interferes with my funnel when filling the tractor with oil. Had to get my wife to hold the funnel while I lifted that 2 gallon jug of Rotella. All basic maintenance operations should require no more than 2 hands in my opinion. Guess they figured you be filling with quarts or one of those handy pumps like they have @ Jiffy-Lube.

I also felt the pain, agree some of the fluid fill holes can be in places awkward to get a bottle/jug into, I realized this when first flushing the hydraulics of my tractor, attempting to hold a 5 gallon bucket over a hole in an area it wouldn't fit wasn't going to happen, I quickly realized I had to first transfer the oil from the 5-gal bucket into a 1-gal jug, and of course by using a funnel that it filled faster than would drain would become top heavy and tip over,

what a mess that was,

if ever you change the hydraulic oil definitely get yourself a transfer pump,:thumbsup:
I do have one now, and quite handy for many uses

Mine sure is happening like that. It will start, but will not run long in that decompression pulled state. Just like the other poster said, chug chug chug wroooom it starts normally. With the decompression pulled it's like wa wa waaa waaaa starts and putters a bunch until the decompression cable is pushed back in. My tractor is a total refurb from the ground up recently from Fredricks Equipment. It's a new cable with all new hardware to the valve cover and linkages.

Still needs adjusting. Ask Fredricks.

I still say if it's working properly,,the engine shouldn't start with decompression lever pulled. There isn't enough compression for the engine to start. I haven't made any adjustments to mine since I've had it, but I hardly every use it. As far as filling with oil. I can't remember all the oil coming in 2 gallon jugs back in those days . I rarely remember oil coming in 1 gallon containers. Most oil in the 80's (that I remember) was in quart containers. Of course, I wasn't into tractors and diesel trucks back in those days

Well I doubt Fredrick's is infallible and though no diesel expert (my father WAS so some rubbed off) I do know that if the compression is truly relieved the engine can't start. However, my 3110 WILL start with the relief in the rearward position which means that either 1) I am not operating it properly or 2) It isn't truly relieving compression. I happened to service my tractor yesterday and while looking through the engine oil fill hole I operated the compression relief. Though I can see the shaft moving, it doesn't look like it is attached to anything. Sure would love to know how the thing works, and what the procedure for adjusting it is.

Maybe they only have quart bottle in Japan???

Thought I would share my final thoughts or rather the way i am using the decompression. When the tractor has sat at least overnight I start it like this:
-Per the YM276 manual-

1. Pull decompression lever and crank over for about 10 seconds max. Stop and crank again until the oil light goes off; usually about three-five seconds more. (Cranking for 10-15 straight doesn't do it for me, this does)

2. Give it about 1/2 throttle push in decompression lever and start the tractor.

If you were starting in cold weather the manual indicates that you would engage the thermostart for ten seconds following step one above. Turn on the fuel, crank motor until it starts, then reengage the thermostart until the engine is "running smoothly". That reengage part got me.

The reengage part gets me too. Never heard that before.

Just personal opinion, not out of a book. If I had to turn mine over 10 seconds and then 3 to 5 seconds more to get oil pressure I would turn over 5 seconds and crank. 10 seconds is a long starter run in my book.

Rarely use it but I pull my thermostart before ever cranking over engine. Again, just my way of doing things.
