Review: Well machined product - These fit the generators such as my Predator 3500. I'm using the #78 at the moment, but that might need to change and this kit gives me selections. Recommended, but be advised, the sizes are stamped on each jet but the text is way smaller than in the photos. To be expected.
Review: Some tuning necessary... - Most of the modern gasoline small engines are jetted so lean that they barely run...especially when temps turn colder. I acquired a wood splitter with a newer Honda GX160 engine. It runs OK during the summer but when temps turn cold I have to set the choke partially just to keep it running...even when warmed up. A thorough cleaning of the carb failed to help. While I didn't need all the different jets that are in this kit I found it less expensive than trying to obtain just one larger size main jet. Turns out I only needed to go one jet size richer, but it was nice to have more options. Bottom line...this Honda engine now runs perfectly.
