Ah... a new reply. Quite apropos as I've been thinking I ought to add to the thread for a couple ff reasons. First of all, I think it may be noticeable that my surging issue was consistent for a while but eventually changed to intermittent. When I went to clean the emulsion tube, it had those...

I should have known that it was running right as a fluke as I never really found anything wrong. It started surging again after about 10 minutes or so of running. Quite bad at times... almost stopped. So this morning I cleaned the carb again. This time I managed to remove the emulsion tube and...

Well, it's fixed, although I'm not sure why and don't have much confidence it will stay fixed, but it's running perfectly now. Seems a combination of problems, but I'm a little vague on the last one. 1/ Cleaning the carb. This did help, but only the first time I cleaned it. Subsequent cleaning...

Story so far: I did remove the welch plug that hides that screw. Screw looked brand new, clean and wet from gas. Havn't replaced that plug yet as I playing with tuning, but so far not really much of anything from adjusting that screw. Next I removed the next plug forward. It reveals 4 little...

T-Y for your reply. The mower is about 12 years old, so it's no surprise that my lack of maintenance caught up to me. It's rarely a problem when I can clean a carb, but this one is a problem. Oddly, the exploded view of the carb calls out a pilot screw under the welch plug closest to the rear of...

I have carb issues this Spring. First, needle was gummed up causing float to stay down and although the engine ran, fuel was flooding the float bowl and pumping out. Got that fixed. Next it was surging or hunting. No doubt a lean condition. I removed the carb, removed the float, needle and main...

I find the manual a little confusing. If I set the spring length as per the manual, the belt tension is almost non-existent. There's also the question of where the measurement is to be made; between the hook ends, or just the coil length. Then there's the note about having it at 30 ft-lbs. Now...

All back together and it works fine. Since the deck is off, I think I'll install the new spindles I bought a while back. Thanks to all who responded.

I didn't do too badly. Just under 3 hours from driving into my garage and finally having the governor mechanism apart. Two slowdowns. The governor arm is a two piece affair (main part plus an extension) and the single screw holding the parts together is a left-hand thread. The other time waster...

Since my last post, I did a little more inspection and I found........... OK, once I type this feel free to call me an idiot.... The carb throttle shaft does appear to be tight and not easy to move. I'll look into this more tomorrow. You know, I even had the carb apart this summer, cleaned it...

Well, not so good news. The governor guide finally came in (Sept 13) after being backordered since August 4th. So today I got the engine out and removed the base cover. All parts look perfect. That's the bad news... I don't know what's wrong. Maybe something was stuck and became unstuck when I...

I did find a YouTube video on it, so now I understand it better. Might not be as labour intensive as I thought. So I decided to look up that plastic guide and it's only about $4, but they don't show a gasket for between the upper and lower halves of the case. There was one in the video, but...

Looks bad. No gov. action at all. (slows down going up hill, etc.) Gov lever doesn't move. ....sigh.........

T-y for your replies. I didn't know there were any as I didn't get any auto-generated e-mails telling me that. Must check into it. I was sort of hoping it was the shaft. I live in the rust belt and the shaft is a bit rusty. I suspected that the rust continued past the outer edge of the seal a...

The governor is sticking, or so it would appear. When I start it, it goes to a very high rpm for a few moments, then settles down to normal. When I change the throttle from low to high and vice-versa, there's a few seconds delay. All linkages look OK and move freely, but governor shaft where it...

I have a DYT4000 mower and I need to replace the deck belt. The sticker under the hood calls for a 144959 belt which is a 1/2" x 95.5" belt. I downloaded an Owner's Manual from the net, but it's for a 917.273643 mower. So far, any parts I have identified from this manual have been the correct...

Yes Rivets, I can't recommend what I had to do. If anything is to be learned, Bert's post already says it.

Finally, almost a year later, the mower is fixed. The surging was from running too rich and any amount of choke stalled it. Here's what I found and how I fixed it. First of all, the new Nikki carb I bought turned out not to be a NIkki,, but a cheap knock-off. That odd rubber gasket swelled up...

Besides my new Husqvarna (which I don't like at all), I have an old MTD with a single cylinder Briggs engine. It had been causing me difficulty over the last year or so requiring constant carb cleaning, mostly due to rust in the float bowl, lack of use (so kept gumming up) and failure of the...
