What is good compression reading ?
Depends if it has automatic compression release. If it is a 2015 or newer chances are it does. 126 psi min on the older ones. 90 psi on the 2015 and up. Normally you would be told that you cant get an accurate compression reading on the ACR equipped engine and they are correct. However after diagnosing these things for a few years now, I can say I’m pretty sure that it’s safe to compression check it if it has the ACR. Leak down test is better if you can get one. No more than a 15% loss. 20% percent is pushing it. I hope this helps.
What is the ring gap on the 401 cc Kawasaki engine
Is there a port that could feed an oil cooler on one of these ? Mine is from an EZGO golf cart.
Will this motor work on an 08 club car precedent?
I have a club car with 401 and it starts hard and acts like it’s running out of fuel all the time I’ve changed the fuel pump and plug but it has no power I just bought it and the papers say the engine only has 15 hours on new crankshaft.
Clean or replace the carburetor.
Looking for the correct piston, rings, and connecting rod, for this motor; I am rebuilding it. Any help in locating the parts is appreciated.
It only has 60 pounds of compression dry and 90 lbs of compression with a wet test I reall wonder if that’s enough and where is the compression release located
What type of fuel pump does it have.part if available
Hello, I want to measure the tool used to pull the clutch Ezgo400cc fj 2016 model. I want to measure the right tool for it
I want to change the clutch for a 2016 Ezgo wagon I want to measure the tool used to pull the clutch I have a 400cc fj engine
