I have seen people use 1/4 NPT fittings on the carburetor inlet, but that can leak or split the carburetor casting. What do people use for an inlet fitting if the CAT part is not available? The book shows a ferrule and collar screwing into the carburetor inlet.

D7 17A pony engine.

Hi Top,
Any good auto/truck parts dealer should be able to supply the correct ferrule & collar.
That D7C of yours is a good tractor. There is a really nice all metal model of the D7C with angle blade available on both eBay and Amazon for $99.99. I bought on to remind me of my father's D7C.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
