Open package today and notice the handle for the “pressure tester “ broken .. Not a good thing given the package was not damaged in anyway and had a lot of overpacking..

The pressure tester comes in a smaller, separate plastic case that will accommodate the spark plug extension. The other tools will fit in the larger plastic tool box provided, but as noted on previous review the box is not great. However the tools are good quality and buying them all at once offers a better value than buying them individually.

The kit arrived on time within 3 days of ordering. Everything looks great. The only thing missing was the piston stop from the E25 timing indicator. A quick phone call to the 800 number, and we have the missing tool being expedited immediately. Very friendly, very professional.

Happy with the quality of tools. Has everything you need to perform compression and magneto checks. I gave 4 stars because the box it came with doesnt secure items, its just any old tool box.

Q: We need a test kit for Rotax motors. Will this kit work? Does the kit include the spark plug adapters for Rotax?

Per our tech: This kit will not work for Rotax motors. Rotax motors do not have magnetos or require timing checks. You'll want to use part number 12-00693 for the leakdown test, this is designed for the Rotax motor and has the 12mm adapter.

Q: Will this test kit work on engines with a greater than 5" Bore, such as a Lycoming 0-540?

Per Vendor: Yes this will work on bores up to 5.25thousanths and I believe the Lycoming O-540 has a bore size of 5.125.

Q: Where is the leakdown test equipment made?

Yes, all these tools are made in the USA.
