[AT] you've got to be kidding me!

John,  I hate to tell you this at this late date but I think you can buy 
that carb kit off the shelf at most any
Tractor Supply store. 
http://www.tractorsupply.com/webapp/wcs/stores/servlet/SearchDisplay?storeId=10151&catalogId=10051&langId=-1&pageSize=20&beginIndex=0&searchSource=Q&sType=SimpleSearch&resultCatEntryType=2&showResultsPage=true&pageView=image&searchType=1000&cm_askwd=&autoSuggestURL=AutoSuggestView%3FcoreName%3DMC_10001_CatalogEntry_en_US%26serverURL%3Dhttp%253a%252f%252ftsc-prod-lb01.crossview.inc%253a3737%252fsolr%252fMC_10001_CatalogEntry_en_US%26catalogId%3D10051%26storeId%3D10151&searchTerm=carb+rebuild+kit

I believe it's the first one on that page that says for IH or Ford. 
Somewhere online there is a cross reference for MS carbs that tells you what 
kits will fit what carbs.
Sometimes everything will work on a different carb except maybe one piece 
that you can salvage from what you have.

Still keeping the furnace at the shop running trying to get things ready for 
spring. Made some more progress on my foam marker for the field sprayer. I’m 
to the point now I’m ready to build something to go on the sprayer and stop 
messing with prototypes. When its done I’ll give a report of the good, the 
bad, and about how much it cost vs a store-bought system. Its looking real 
promising at the moment!

On to yesterdays shocking revelation. Still got dads 454 IH utility in the 
shop. Got the brakes fixed after the second attempt. It originally came in 
to get the radiator pulled and repaired. After the brakes I needed to use it 
so I did. while checking brake lines for leaks, I found the head gasket was 
leaking in multiple places. Its at the shop now getting all “prettied up” 
(just my luck it had to have guides!).  In the meantime I set about finding 
a carb rebuild kit that had a throttle shaft. Long story short I searched 
coast to coast and finally find a kit that had the throttle shaft. Paid a 
small fortune for a venturi as well. The carb on the tractor has almost 
8,000 hrs. on it, lets just say its worn a tad bit. By the way it has one of 
those cast iron TSX Marvel carbs. 25-30 years ago the mechanics at the IH 
dealership dad worked for were working on the same model tractor. Rebuilt 
the carb a couple times, could not figure out why the tractor wouldn’t run 
very well. Finally they put a new carb on the machine. Dad brought the old 
one home and it has been collecting dust ever since. When I saw how bad the 
throttle shaft hole was in his, I decided I would try my luck rebuilding the 
one that the mechanics had given up on. Had it all apart wire brushing it, 
couldn’t help noticing how clean it was inside. Searched it for every hole I 
could find to run a wire in. Saw a piece of crud on the outside beside a 
small hole. Scraped the crud off and there it was, a huge hole that appeared 
to have been soldered over! When the carb was made, there are some interior 
air passages that go from the throat into a cavity located above the bowl 
area. This hole was drilled too deep and actually broke out the top of the 
carb right above where the float would be. I feel this was a factory mistake 
because the overall depth of the hole is pretty shallow to begin with. and 
being 1/4” in dia., you wouldn’t go spinning a drill in it to clean it out 
when you can visually see thee is no obstruction. This small hole was 
allowing 2 things, water and trash could go straight into the bowl, and the 
throat of the carb could pull air direct from the outside, even more so than 
a worn throttle shaft could ever cause. Anyway, I’m taking it to work to get 
the hole TIG welded shut and then we should be back in business!
