When I ran my generator last week, it surged, which is not good, since a surging engine causes surging voltage. I removed the carburetor, cleaned it thoroughly, reinstalled it and checked the operation. I still have a surging generator.
I did some research online about the problem. There are two possibilities I need to examine. One is the fuel tank valve filter. I haven't ever removed it, and there's the possibility it's partially clogged. If I can't remove the filter, I'll remove the valve, and either replace the valve, or remove the filter permanently. I'll install an in-line filter instead, which is probably the best solution.
The other problem may be the fuel solenoid on the bottom of the fuel bowl. If it's weak, it might not be holding as needed, which will require replacing the solenoid, or the carburetor, if that's not a part that is replaceable.
If neither of these solutions stop the surging, I'll go back to my head-scratching mode and continue my effort to not depend on a mechanic. I try to never let a small engine defeat me.
Interesting. What kind of genny and how many whats, Jess? Please keep us poosted...
ReplyDeletePredator 6500 (Harbor Freight). So far, the fuel shut-off isn't a problem. I'll replace the fuel line. It has some small cracks, which can go all the way through and suck air. After that, I'll have to order the fuel solenoid. It runs around $15. That, or just replace the entire mess for about $45. I'll know after a trip to the parts house for fuel line and new clamps.

ReplyDeleteI just ordered the carburetor, with the solenoid, gaskets and other miscellaneous parts. Delivery is tomorrow, the reviews were good, and it was only $21.
