Time Spent Repairing:

15-30 minutes

Tools Used:

Screwdriver, Pliers, Socket set

Recently, the engine started running rough and the choke had to be completely closed to operate for awhile. Then, the engine would start, but would not run for longer than a few seconds.

1. Removed the carburetor and dismantled it. Removed lots of sediment from the carburetor bowl. Cleaned the varnish off of the float, main jet, slow jet and bowl. Noticed on the slow jet, that the O-rings were damaged (one was swollen, and one was broken). The O-ring around the bowl was dry and brittle. I replaced the slow jet O-rings and the bowl O-ring. Since the O-rings on the slow jet were a type of rubber and the float needle tip was a type of rubber, I replaced the float needle just in case the rubber tip was damaged. After making these repairs, the engine started in two pulls and ran smoothly with the choke completely open.

Gummed up carburetor

The Subaru Robin engine carburetor is easy to rebuild. Mine was gummed up/dirty from setting too long. Removed air cleaner, linkages [surprisingly easy], and carb. Replaced needle valve, float, main jet, and o-ring. The majority of the time was spent cleaning the bowl/innards. It was a snap - reassembly was also a snap. Engine ran like a champ. Should have ordered all the gaskets too, but Permatex 2 worked for me.

Christopher - January 5, 2021 Verified Purchase

Parts took forever, can’t help factory delays

Haven’t fixed my generator yet, at least I have parts

Guest - October 13, 2019 Verified Purchase

reorder required

The web site had 2 sets of drawings for the same model generator. The first part I ordered was incorrect and I had to reorder. This was true for several parts. The customer reps I talked to were very courteous and helpful in setting up the return and getting a refund. I did get the correct parts on the second order but not because anyone helped me to identify the correct parts.
