Replace GENERAC generator in a Gulfstream

Did he check valve lash ?

525 hrs is pretty low, it should not be low on compression. Have a compression test and a leak down test done on the motor.

My 1st post so I’m probably doing something wrong, and I’m uncertain how to address this to the OP.

Anyway I’m trying to see if OP was able to solve his problem. I have the same genset with the same B&S V Twin engine....still get most parts but some, like carb are obsolete.
My carb was also gummed and not working when I got my new to me MH...2002 Newmar.
I was able to repair carb and get unit running, but now I have hard start issues due to what I think is low compression. I’m trying to weigh repair vs replace engine, but I’m unable to find a compatible replacement.
Unit has 525 hrs according to meter, so I think it would be economical to replace whole engine. But other then model # I have no hp specs on engine. Local small engine shop was no help.....#303775-0110-01.
Anybody know a source for replacement engines?
Thanks in advance

I know this sounds strange but check Amazon. They have several carbs for Generac.
I have bought several carbs from them for other things and all have been good.

I just had the Onan 4000 genset and it's fuel supply system gone through by a well recommended generator shop. Cost was $794. Also replaced two 6volt 4 year old house batteries. Good advice is to run generator for two hours per month with AC on for a load to keep it running reliably. Also, house batteries need to be kept charged and with electrolyte covering the plates, use distilled water and rubber bulb filler. Keep terminal connections clean. Check voltage with digital multi-meter while resting and while running the chassis engine or RV generator. Worth being a little obsessive for reliable genset operation.

At one time Honda made two great RV generators. 4010 and 6010 were great packages.

Notice I said WERE.

Look around for a small engine repair shop to rebuild yours!

I spent $2000 having my 2004 Generac completely rebuilt last year; but, was a lot less than buying a brand new unit north of $4000. It's all in how you consider "cheap repair". Good luck.
