  • Easy to use, and works as described
Color: Red
I purchased one of these kits to test a 50hp outboard, and it worked perfectly. It's been a good addition to my toolbox, and I've already used it on a few other engines I had around the house out of curiosity. The kit seems well-made, with all the necessary components/adapters included. I'm not sure how well it will hold up over time, but I think with light use, it should last awhile! ... show more

  • Worked great
Color: Black
I tested the compression on my 2009 Camry with this and it worked very good. For the price I believe it's a good value.

  • Horrible quality
Color: Red
BUYER BEWARE!!! When performing a compression test the line popped off of the fitting leaving the fitting stuck in the cylinder head. Luckily i was able to fish it out by removing the valve cover and twisting it off with some needle nose pliers

  • Not useful for 14mm or larger
Color: Red-1
My use case is for old Fords (FE Big Blocks - 390, 428, 410) and this kit does not have a large enough adapter for my spark plugs. Looking it up (after the fact) the old engines used a 14mm spark plug thread, this one doesn't come close. Returning this kid and ordering slightly more expensive kit. It will be here tomorrow, hopefully it works. I believe common 4 stroke lawn equipment uses the same size threads as my old engines. ... show more
