I finally finished refurbing the 44A deck I've been working on for my grandson's 1250. I gave it a quick test-run tonight on my 1450 and I'm really happy with the results! It's hard to see it in the photo, but it's a really nice even cut.
Thanks to everyone here who provided answers & advice. And to Dave Schwandt for the belt cover - you can see a little of it in the photo and it looks great. And, of course, thanks to Charlie & CC Specialties for all the parts (and extra freebies with each order).
Don't judge the appearance of the old 1450 too harshly - she's running better than ever with the new carb parts. You can see in the photo that I had previously given up on the mule drive and converted it to a front suitcase weight hanger. Now I've restored the mule drive, but decided to leave the weight bracket on, with a little IH bling!
Thanks again everyone - I wouldn't have even started the project without this forum at my disposal.
Oh, I almost forgot - I finally found a fuel line shut-off valve for my 1450, that I can access without removing the side panel. I know it shouldn't be necessary now that I've replaced the float needle valve and seat, but I'm much more paranoid than I am confident in my mechanical abilities, soooo...
