Engine Parts Identification Chart

ďA Never Ending SearchĒ
(Courtesy of Hit & Miss Enterprises, Ed Deis, family & friends -Orwell, Ohio)

Being in the partís business for over 30 years I have come across many unidentified engine parts that have been laid aside and long separated from the engine they came from. I have a bin full of such parts and always felt I could help somebody with some of them if I simply knew what they were for, especially the ones that had the part # cast into them. I thought it would sure be nice to have a reference chart that gave part #ís in numerical and alpabetical order and identified the engine they belonged to. And how about if you acquire a new engine with no nameplate and not sure what you have? If the manufacturer of the engine had the part number put on the castings that reference chart might identify your unknown engine. And again if you had such a reference chart with you when you were out at the shows looking for parts it would take some of the quesswork out of buying or not buying something that may or may not fit. The research for this chart will go on continuously and will be added to by all of us as new information comes in. Thanks to computers and the internet, you will have instant access to the most current chart. You will be able to watch and hopefully contribute to itís data base. Unfortunately there are engines with no casting numbers on the parts. Eventually we will list these engines along with some pictures of the engine and individual parts along with helpful notes. There will be plenty of footnotes giving useful information-much of which canít be found in instruction manuals, but from many years of experience of working on these engines. Again not only from my experience but also of those who have and will be contributing to this venture. We are unlimited as to what we may do with this publication and someday this may be part of an intensive book on stationary gas & kero. engines, incorporating known and little known facts and trivia. I could have kept this as a private for profit venture, but I would have been limited to just what I know, which is a drop in the bucket compared to what is involved in this hobby. So, what we need is Your Help! I need you to send me casting numbers of parts on your engines so that we can add them to the database. Please include the following information if possible:

Engine Name
Serial #
Ignition type
Flywheel diameter
Piston diameter and stroke

Of course, feel free to include other information on the engine as well if you think it is unique or important. Then, simply list the part names along with the casting numbers. I look forward to working with all of you and hope you will all contribute and certainly correct any misinformation and offer suggestions for improving on this database! Ed

Please feel free to e-mail us with your thoughts, suggestions and, most of all, your part numbers! sales@hitnmiss.com

We keep updating this as folks send us information and we're making headway!
