General preventive maintenance Here is what you should do at the end of the mowing season: If you do nothing else in this list, at least change the oil.

TECUMSEH AH-HSK600 Quick Reference

Often, homeowners can adjust the carb themselves and save the time and money of taking the machine to a dealer or shop. Make sure you are parked on a flat surface.

I’ve found that most of the problems with engines are pretty simple once you’ve seen them so I’m planning to document what I can to make “Fixin’ Mowers” simple. Here’s what I’ve documented so far: If the mower was running just fine last Fall, and will not start in the Spring, the first thing to suspect is that the gas has gone bad.
If it just keeps running worse and worse until it stops or doesn’t start , it could easily be the air filter. This is what a ” Fouled Plug ” looks like. Here’s a “quick” cleanup.
Cleaning Craftsman Tecumseh carburetors Simple float carburetors are found on a variety of equipment including many engines made for Sears by Tecumseh. The basic procedures applies to the float carburetors of other manufacturers as well. If you have been following the recommended preventive maintenance procedures, this may never be needed.

Win XP Hi, everyone! Allow me to explain the difficulty. It is due more to “operator error” than the machine itself. I garaged it until yesterday, determined to ‘noodle out’ the problem. Before refueling it, replugging it with a new plug, I decided to take a look at the carb to see if there was any junk in or near it, and that’s where I de-railed myself.
Removal wasn’t totally intuitive, but I figured it out There’s a small 90 degree ‘Z’ bend in the end of the cable that goes into the ‘cam’ for lack of a better word..

I am by no means an expert on fuel. And I am confident that I have seized more pistons in those 28 years than any other human on any continent. Gallon jugs of industrial strength muriatic acid, used to dissolve aluminum smeared onto cylinder walls by pistons trying to grow larger than the bore size , are cheaper when you buy cases of four! And we now listen to knock while testing so damage from deto is now rare. A combination of low velocity airflow from huge carbs and low volatility fuel requires lots of engine heat to create adequate vaporization.

Chokes have been a thing of the past on motors used on push mowers for quite a while, not because of emissions, but because people do not know how to use them properly. A primer bulb works better, but people still manage to mess that step up also. The new hondas on the lawnboy mowers have a thermostatically controled choke. The choke is engaged and then a temperature sensitive spring opens the choke slowly or quickly based on the ambient temperature. Though I agree with what you have said about fixed throttle and chokes being misused.
Emissions is indeed what manufacturers are after with chokeless and throttle fixed small non road engines.

Chris Ed Miller 7 October Chris – The link to the manual did work at 2nd try, so the site owner probably had the link down temporarily. I bought two parts to replace the tineshaft oil seals, but I noticed a problem with spacing. The tine assembly has just under 2″ between the bolt hole and the inside edge which buts up against the housing or gear cover on the left.
Does anyone else see this problem or is the tineshaft no sitting in the proper place on this unit, which might mean there are other problems inside the transmission housing. Any insights would be appreciated. Ed 07 October Ed I have not had to work on my tiller’s gears yet, so I do not have any first-hand knowledge to provide.
However, looking at the exploded view and the accompanying parts list, it appears that the seals are identical for both the left and the right sides they are both listed as 3 on the parts list.
