Hi guys and gals!
My first post!
I found this forum searching for a solution to an issue with my GVC 160cc Honda Engine model GJEAE. It is the engine with a fixed throttle speed range, type 4 I think. It is OEM on a Yardman-MTD.
My neighbor could not get it to start this spring so he bought a new mower. He said he used it to mow his yard for 5 summers. I saved this one from the dumpster. My mower repair experience is limited to Briggs & Stratton engines, so I could use some help with the Honda engine.
First thing I did was disconnect the fuel line and drain the tank. I could see trash and a few drops of water in the bottom. Next I drained the carburetor bowl. Then refilled the fuel tank with fresh fuel. Next tried to start it, but nothing happened.
Second, I got online and figured out how to clean the carb. I completely dis-assembled the carb, removed every jet and cleaned every orifice. Re-assembled the carb and turned on the fuel. When I pulled the rope nothing happened. I shot a small blast of carb cleaner into the intake and then it started the first pull of the rope. It would continue to run, but was surging from idle to maybe half throttle. Turned it off and went back online.
Third, next morning while the engine was cool I pulled of the valve cover and adjusted the valves. Both valves were really out of spec loose. Installed a new air filter. Installed a new blade. I removed the spark plug and cleaned it. I removed the muffler and made sure it was not blocked at the spark arrestor. When I got it all back together and tried to start it, nothing happened. A shot of carb cleaner into the intake and it started first pull. The surging was gone. I mowed with it for half hour until it was at operating temperature. Then stopped and changed the oil. After changing the oil I pulled on the rope and it started 3rd or 4th pull, full choke on. Then I turned it off and it would not start again. I went through the carb again, every thing, removed the jets and probed every orifice with wire. It's cleaned thoroughly and I can see through the every hole! Put it back together, and still it takes a shot of carb cleaner to get it going.
Fourth, this morning pulled on the rope several times, would not start, using full choke. It is not flooding. A shot of carb cleaner into the intake and it fired right up. When I turn it off and try to re-start it, I can not get it to fire up unless I use carb cleaner to prime it.
Compression seems good, though I have not checked it with a gauge.
My question: Why is the engine not pulling enough fuel from the carb to start up?
Thanks!
Alan
