[quote=&quot;hart70octaneparr&quot;:2fys4ovv]For any spark ignited gasoline engine, choke on to run means LEAN.

Check for a clogged main jet, opening a needle adjustable main may be enough to let the crud (technical term) pass and open up the passage.[/quote:2fys4ovv]

Thank you for the tip...I will adjust that main out and run it and see what happens...I cleaned out the sediment bowl yesterday and it was half full of what appeared to be rust...so I think we can assume the carb is clogged at this point....will get that off soon and see if I can get it cleaned out and adjusted better.

Still trying to figure out exactly the year and model I have...the seller told me parts for a 770 fit it...but he did not know the model and year either...that would be a big help if someone can ID the numbers..

Now on to a new BIG problem that happened yesterday...keep in mind I have not worked the thing at all (and am completely inexperienced).....we got it off the trailer , spun it around in the yard a few seconds and parked it thinking I would get back to it to work on the choke/dogging problem etc...so yesterday was the first time I actually tried to run it....as its 2 hours away from my home at a land parcel I bought....SO, I cleaned the sediment bowl, fired it up and started running up a rough road I cut into the woods...I got about 40 feet into the woods and it dogged out and I couldnt get up an incline...so shut it off and tinkered some more and got it running a little better...NOW, go to put it in gear and start trying to make the hill again and NO GEARS! I can;t move thew thing at all...tranny just stopped working....its one of those &quot;no clutch&quot; transmissions...looking on tractordata..they call it &quot;sliding gear&quot;? 6 forward and 2 reverse...Automatic tranny? Anyhow, I tried everything I could think of and can't get it to engage at all...sprayed up linkage etc..etc...The tranny fluid is the only thing I didn't check for some reason...so I look for a dipstick but nothing...just a filler cap..there doesn't seem to be a level plug either..just a drain plug on the very lower side of the tranny.....so I poke a stick down and it comes out dry...look in with a flashlight can't see anything in there..don't really know if there is anything in there or even if there is supposed to be...I poured in 3 quarts of hydraulic/tranny fluid I had there with me...don't know if thats the right stuff to put in...but all I had with me...it still doesn't engage....now what?, stuck in the woods with the thing...
