Questions & Answers

Do the parts come in a storage case or are there loose parts to store them all in?

I just found a Tupperware container to store it and all the parts in, as it does not come with a case.

What is the fit of a 13/16 size spark plug with this?

Hi Jakee, I tested the compression of my Chevrolet 327 CI engine, which uses a 13/16" spark plug, with the Innova 3612. A pressure valve on the tester started leaking shortly after it was constructed, but the tester worked fine after that.

What do you think about a Poulan weed eater with this?

These engines have very low compression when cranking, so it should work.

Is there any experience with this on a Toyota Corolla or Camry?

The spark plugs have to be accessible to work, but I used it on a Nissan Maxima, so as long as you can access the spark plugs

Selected User Reviews For Compression Tester - 4 Piece Kit

This is junk! Make the most of your money by spending more! It was almost time to scrap a cheap saw because it had no compression, the needle was installed behind the pin

3/5

I would buy a better product, as this one felt cheap and probably would not last a few.

I think you may have a problem with the update

3/5

My current vehicle is my third one that I have used this on. In order to ensure that the operation of the used vehicles I buy is in good working order, I use it to test their compression. There is no way to tell if a cylinder is on its way out when it hasn't yet begun to show signs of wear and tear. Then you will be able to determine whether you need to walk away right away or if you will need to make some costly I find that this tool works very well and is pretty accurate so far. This kit comes with a variety of fittings to fit different types of plugs. The following is an update as of As of now, the gauge displays 45 psi when it is My phone never drops or gets abused and this started happening when I attempted to use it for the first time since I started using it. It also leaks air pretty profusely, which gives false readings on cylinders in addition to the gauge being wrong. The pressure reading of the friend's unit to compare to this is way off, both from the initial reading, with a 45 psi adjustment, as well as the pressure holding. Initially, the device seemed to work well, but it ended up not lasting as long as I would have hoped. I will have to get.

This is junk

3/5

I purchased it as a chainsaw test. There is too much adapter on the piston, so it hits it. Compression tests can't be conducted because the seal does not hold well.

This is not intended for Suzukis

3/5

The compression test for the hayabusa couldn't be performed due to the wrong fitting. Suzuki is the mainstream A fit can not be made.

This is inaccurate

3/5

Perhaps this was just a bad gauge, but it read 150 psi when the cylinders were actually compressed to 190 psi. Based on my experience, this was determined to be a Did the majority of the 5 star reviews actually confirm that the gauge works? How can you ever trust the gauge if you do not do so? If I had been relying on just this gauge, I would have thought my motor was junk. The fact that reviews are usually useless shows how useless they are. It is generally more useful to look at the one star rating if you want to get a better sense.

A test was conducted on this particular specimen to determine its accuracy

3/5

My purpose for buying this particular item was to perform a test on my Stihl FS-100 I sent it back since I was not aware that I needed a 10mm fitting for the spark plug. You need to buy the Inova 3614, which has that adapter. I wish people would not make assumptions about a product and what it is capable of before finding out more.

Don't waste your money on cheap stuff buy quality

3/5

My jet skis require attention - I bought a new tool to do just that When I tried on the first ski, it worked, then I tried on the second one, but it didn't work. Are you sure?.

The item was defective before it was used

3/5

On the wrong end of the pin, the needle was installed. Even so, I tried to use it anyway in hopes it would fix itself, but I had A quick access to this tool was critical for me. It's now a complete loss to me.
