Small Engines (Lawn Mowers, etc.)/2000 Ezgo running eradic


QUESTION: Hi, I have a 2000 Ezgo golf cart with a 4 stroke 295cc motor.  It runs fine most all the time, but occasionally will run half speed and then all of a sudden kicks in to normal speed.  I just put a new carb, air filter, fuel filters, and plugs in but it still does the same thing. Any ideas what I should be looking at next?  Thanks

ANSWER: What brand of engine is on the cart?  Is the throttle control sticking or binding?  Does the engine idle fine?

Let me know.

QUESTION: Eric, I think the engine is a subaru.  Did not see anything sticking.  There is no idle, it is run or stop. The problem was there before installing the new carb.  When I start it and go sometimes it will be running half speed and then it will just kick in and sometimes after it kicks in it sometimes will kick back down to half speed again.  Could it be the coil or the fuel pump?  Thanks

I doubt the ignition coil is the problem.  It would have to be a very sophisticated ignition system to cause the problem you described.  I have seen one ignition module with a unique problem but the problem was consistent...would not run at all on high speed.

It could be a fuel pump but without knowing the engine it is difficult to know what type of fuel pump is on the engine.  Is there any way to watch the carburetor linkage when the problem occurs?

I am wondering if something is binding in the governor system.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
