South Puget Sound - Mobile small engine mechanic?

[Peddler]

I have a 20kW propane-fueled Generac generator that is showing symptoms of needing work that's above my skillset.  A couple of weeks-ago, it must have had a pretty good "after fire" through the exhaust, as it split the muffler wide open.  The genny is about 15 years-old, and really all I've done for maintenance is spark plugs and oil/filter changes.  I've never checked/adjusted valve lash, don't know how to do anything with the fuel/ignition systems.  It's always pretty reliably started for it's weekly exercise.  If I notice it doesn't fire on the first start-up attempt, I install fresh spark plugs and away we go again.


After this muffler incident, I installed new plugs, and she fires-up and sounds like it's running fine (although quite loud, obviously).


I'm having a heck of a time getting someone to come look at it.  The few "small engine" shops around Olympia aren't mobile. The one solid referral I got won't travel to Oly from Puyallup.  Does anyone have a referral?

I've installed several of these.  But, I just handle the electrical part of the installation.  I don't do the engine maintenance or repairs.

I'd be curious as to what caused that muffler split.  That just doesn't seem "normal".
