Hi this is my first post on this forum. Thought I would ask the experts here a question. I have a Generac 5500XL Model# 9778-7 generator. The last time I had had it running for a significant amount of time was in Jan. It had been a while before that. I have this on a cart for easy access from an out building. After it had been running for about an hour or so I added fresh gas to the tank. I’ve also been using Stable in the gas. I restarted it and it ran for a while. I repositioned the cart and after moving the generator it started to lope. It continued to do that until I shut it down and put it away.

I got it out this past weekend and tried to start it. It ran briefly for a few seconds and then it quit. It sounded to me like the choke wasn’t adjusted correctly. After trying to start it without any success I noticed an amount of gas running out of the filter onto the cart. To me it acts like it’s flooding out but that’s way too much gas coming out IMO. I’ve tried to start it without choking it and I still can’t get it started. I also changed the oil and filter. Anyone have any suggestions as to what to look for first?
Thanks!

I assume that the gas is comming out of the fuel filter? Could be that air is getting in the fuel line and not letting fuel get to the carb. Or you could have some dirt or gunk in the float bowl. replace the fuel lines, filter and clean the carb and then try it ad see what happens.

Thanks, I got it running today with the help of a friend. The float was leaking and it was full of gas. The float was replaced and it’s running great. However, in replacing the float something must be set different than what it was before. I can barely tell a difference on the idle down without load. Does anyone know if this can be adjusted or if it will cause any problems? I’m presently test running it with a load. It is running now and the load for this computer is coming from the generator at this time.
Thanks again!

Not sure if float height would affect that or not but it's one thing to check... assuming someone knows the required setting.

I use Seafoam in gasoline units. It helps clean out the carb and helps with water in the gas.

Also make sure that ALL gasoline run through the generator (or [U]any[/U] seldom-used gasoline engine, for that matter) is treated with Stabil. I've cleaned out many a carburetor for neighbors who've tried to run stale old untreated gasoline and clogged up their carbs.

There should be a soleniod on the top of the engine with a adjustment just loosen the nut and with no load and the idle switch on adjust it down.
