Said that all Model A carbs have adjustable mixture controls. Asked him for Models 1617, 1821 and 1821S but said that in the Model A area they only refer to the carbs as a Model 1, 2, or 3. Also said that Zenith stopped manufacturing these carbs which is why they are not available from GP and JW Whitney. Rebuild kits are still available which is what he does for the Model A crowd. I'm told that the Zenith carb is probably the best alternative to the $900 Ellison. I'm looking for an 1821S for a 2180 Type 4. Can anyone correlate the difference in Model numbers?? Tnks, Bob ---------------------------------------------------------------------- Subject: Re: Zenith Carbs From: "Rod Kelso" Date: Tue, 7 Dec 1999 09:46:03 -0500 X-Message-Number: 3 Bob, You might check into your nearest Ford Tractor Dealer. The old 8N and 9N Ford tractors used the Marvel Schebler carbs that are identical to the Zenith. These carbs where also used on the Ford Jubile and 600, and 800 series Fords. Ask the dealer for FOMOCO prices and then ask them to check the Tisco price list. Im not sure who has the best deal on carbs now, but 10 years back Tisco had the better deal like 50% less than Ford. The 800 series Ford Tractor was a 4 cyl overhead valve engine where as the 8N and 9N were flat heads. Hope this will help anyone looking.

Jim, Last night I checked out my friend's pizza oven. The oven's sections are big enough to accomodate a 2'x4' piece of plexiglas, but only the bottom section is high enough to fit a piece that needs to be curved. Pizzas are usually baked between 550 and 600 degrees F and they produce a more uniform heat than a regular home oven. Another thing you could look into is an artist's kiln. If you live near a university that has a Fine Arts department, they usually have huge kilns to dry out their pottery and things like that. It never hurts to ask. Just tell them that it's for your art project! ;-) Happy Building, Albert Pecoraro mailto:apecorar@steelcase.com ---------------------------------------------------------------------- Subject: Re: Zenith Carbs From: Donald Reid Date: Tue, 07 Dec 1999 16:30:45 -0500 X-Message-Number: 5 Rod Kelso wrote: > You might check into your nearest Ford Tractor Dealer.

You can try Central Tractor, they are the J.C. Whitney of tractors. The carb on my 9N is a side opening, updraft flow that could do just fine. There is an easily adjusted mixture control. In tractor use, it is adjusted with a screwdriver, but a cockpit control could be fitted. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Re: Plexiglas Questions From: "Timothy Bellville" Date: Tue, 7 Dec 1999 17:42:46 -0500 X-Message-Number: 6 -----Original Message----- From: Jim Sellars To: KR-net users group Date: Tuesday, December 07, 1999 10:24 AM Subject: [kr-net] Re: Plexiglas Questions That would be fine,as long as the oven is big enough and maintains a constant temp.

Great Plains lists different sizes of Zenith carb for different engines, which I assume are different throat sizes (?!?) I assume the tractor places would ask you what tractor you want it for in order to figure the size. You'd have to fake it because obviously you can't tell these people what you want to buy the carb for. So is there some reference manual that shows what size carbs can be used on the different engine sizes of tractors?
