Re: Tillotson AJ29A x

I have an AJ-29A on my 1947 KE-7. The parts list indicates this as the service replacement for the AJ-19A that was original on the KE-7. This is the only one I have yet had on the water, so I really can’t compare it to the original AJ-19A on the KE-7, but it does have a larger bore than the AJ-19A. On my KE-7, it performs wonderfully! This is a really fun motor, and is on my "If I could only have X number of motors." list. I have replaced the AJ-19A with the AJ-29A on one other of my KE-7’s, and my third KE-7 will have the original AJ-19A. Unfortunately this year was so busy with my daughter and other distractions, that I didn’t get as far with the restorations as I had hoped. I also have two KF-7’s with the AJ-29A carburetor. This carburetor is again a bit smaller bore than the AJ-32A that was used on the Hurricane blocks vs. the Lightning blocks. (The porting is different, and 8 reeds vs. 4 reeds), so they can use the larger bore. I don’t know how an AJ-32A would do on a regular Lightning block, as it may be too much. I tend to think it would be fine, as the KG-4 used them and they were less displacement.

I really need to get these motors finished and run them to have a good comparison to go with. Like I said, in my experience, the AJ-29A has been a great success for me. I have a NOS body, but it needs everything. I would not pass on one at a swap meet to put on my shelf.
