    Go to Ebay - search for "marvel-schebler" - lots of carbs and parts there.

    cheers,

    errr? hotmail? you know i don't know anything about modern technology?!?!?!

    anyway. is fuel making it out of the tank? don't know anything about the cases, but i'm guessing yours has a mechanical fuel pump? or is it gravity feed from the tank?

    gas quality is pretty bad about gumming these days. with your winter i would look at a stuck needle valve above the float. i would probably try opening the carb bowl float (probably a small plug in the bottom). remove the fuel inlet line at the carb and try spraying in carb cleaner. if it makes it through the needle valve it should drain out the bottom. if this happens and it does not help. then:

    maybe gas metering orfice is stopped up. take out fuel adjustment screw and try the carb cleaner there. (note number of turns out so you can replace screw in about the same mixture.) if none of this helps....time to take carb off tractor and start cleaning.....if you are carefull, you might not need a gasket kit....i don't have a reference for the cases,,,so don't know which model marvel you have. but try www.VALU-BILT.com

    i once had problems with a marvel on an international H, after taking the carb apart several times, i found a broken off drill under the metering orifice. i guess someone tried to clean the passage with a drill.

    Don't understand this message at all, what did you mean to say? ;)

    Valu-Bilt sells a lot of remanufatured or new carbs for old tractors, _if_ you had a model # maybe could find one their. They have a wb site, but a phone call will get you a lot farther on finding stuff, they do the best they can with the web site....

    The junked out tractor carb is not going to be any better and maybe worse than the one you have. Find someone that can clean your carb and put in new gaskets. There is probably very little wrong with the carb you have.

    I agree with Agmantoo on this issue, find a retired mechanic and let them go through your unit; they might do it just for the fun of feeling usefull!

    The Rebuild kit is the way to go. It should be NO more than $30.00 and its easy to do.

    Found the box of old carbs/pieces but I fear it is of little overall value. The folks previous have nailed it for you. I am betting it is a gravity feed with a sediment bowl/shut off valve. IF the valve will still shut off, remove that bowl and clean it and follow path on down to carb. These old carbs are pretty bulletproof and simple. If you are not sure, make notes as you proceed. Worst case likely a kit-try NAPA-you might be pleasantly surprised. Instructions generally included with a blow up diagram. Luck, Dan

    I stated the modle number in a post up the line. The case is a 440, 1967 year. I used 2 Zenthis and a smaller S_M. I used the throttle buterfliy off the S-M and the rock arm off the Zenth. The third cleaning was a great help. I had to solder the opening to the throtte to adjust for slack so that the goveror would keep up. So far every thing is doing well. I am sorry I can't express myself well, I guess my hands are able to do things better then my writing. Thanks for the advice. Sorry I was confussing.
