One added comment to the carburator that is corroded from rain water....
Could you not find a cheap lawnmower (100$) at some retail store , say MALMART, inwhich you could buy it and remove the side draft carburator to accomodate your machine? Now 3.5 HP machine's carb is smaller than the one on your goat muncher but it would still provide a 14 to 1 fule to air ratio and function as a grass cutting machine for your purpose. Then you could resell your machine on Craigslist or Ebay ?
Yes, you are correct. They would have taken it to their local dealer and paid the high price for a new carburetor. When your income would pay for a new carb with a couple of hours or days work, it is very easy to justify. That is possibly one of the reasons the prices are so high.
When this happened, the new engine could be purchased for $1200. Paying 1/3 to 1/2 the price for a new engine for a carburetor should not necessary.
I appreciate your comments. That was my first response to my problem. I went to motorcycle shops, racing gocarting ships, auto repair shops and suppliers. I attempted to identify a aftermarket motorcycle carb, since there are very few 25 HP automobliles around anymore. The problem is no one is interested. There only seems to be "professionals" not hobbiest. If they cannot look it up in a book, they cannot help.
Another problem is I am just not motivated. Since our move across the country, my lawn is so large, it takes less time to mow it by hand. I will have a large area to mow in a few years, so I do not want to sell it (who wants to buy a mower without an engine).
FYI. it is not mandatory to purchase that original carburator. If you can determine the CFM flow for the 23 HP engine , you could buy any small engine carb and machine a simple adaptor from base of carb to block intake. Also adapt the accelerator cable to accomodate the replacement. If you bring the lawnmower to a savy motorcycle rebuilder or even a garage mechanic with some engineering know how I am sure you can get that machine mowing in a weekend.
Not complicated science here just a lack of American know how!
Since I've become "affiliated" with the lawn care industry I can tell you that there are several parts suppliers that can supply you with anything for that engine you may need and from stock. It's a very popular and reliable engine. A new engine is probably around 2k but I can't see the need for that. One of the advantages of owning a pro grade machine is service and parts availability. Imagine what would happen if a lawn care operator had his machine go down for a couple of days. You are having problems because you don't know the right places for parts.
Thanks for the tip on STA-BIL – Now that you mention it, I do vaguely recall hearing about it; mixed in with the other Paul Harvey favorites such as CITRI-CAL. So, thanks for ,,,, the REST of the Story ! --- Good DAY!
I suggest you stop in at any auto parts outlet. Paul Harvey for years advertised a product called STA-BIL. It is specifically marketed for gasoline engines which are used only occasionally during a calendar year...... your A/C Generator in S. Fla, someone else's snowblower in N. Dakota, etc.
General comment: I had a KAWASAKI INVADER 340 snowmobile in the very early 1980s. It was a sleek-looking, vehicle with a liquid-cooled engine. It was designed & assembled in the good ol' U.S.A, in Ohio, in fact. But, it's performance & that of the Customer Service Dept. were horrendous. It was ONLY comfortable running in a near "flat-out" mode across a frozen lake or large, unobstructed field. FORGET trail-riding w/ its moguls, slow pace, twists & turns. The "tunnel" radiator was insuffieiently sized to dissipate the heat geneated by the engine. The temp gauge would peg in the HOT zone within a literal few minutes of slow riding.
Repeated calls to the factory went unanswered. The selling dealer had previously disassociated themselves from the KAWASAKI brand, so they were unsympathetic to my plight.
After a few years of totally disappointing ownership, AND with noticably declining snowfall in the region, I elected to sell it, and end my seasonal snowmobiling activities.
It's NOT the "rice-burners" as one blogger suggested. Besides German-made motorcycles, I've owned several HONDA motorcycles. They're at the top of their game in this regard.
I totally understand what you're saying, tekochip, it just doesn't make it much easier or economical for the consumer. Isn't there a better way? Using composites or other less expensive but more durable materials, perhaps?
For some applications I have been succesful with the blue silicone gasket liquid that comes in a tube, using it as a substitute for the gasket. For replacing a complex gasket the task can be tedious, but the satisfaction of not needing that very expensive replacement is a good reward. And occasionally it is possible to make gaskets using bulk roll type gasket material.
