Onan spark arrestor

I have a question about the spark arrestor on my Marquis Gold 7000 - gas generator. My genset has about 150 hours on it and I have never cleaned out this spark arrestor.
Has any one else done this - how necessary is it? I would have a bit of a concern with the 7/16 plug being stuck since I have never had it off. It does appear to have a small bit of rust around it.

My generator is running fine - but I thought I should do the maintenance on this plug arrestor since the Onan schedule calls for it to be done every 50 hours.

Comments? Suggestions?

My guess is that most motorhome owners have never done it nor had it done. IT is on the Onan maintenance schedule, though. I know I haven't. I heard of one case where apparently a dirty spark arrester caused the genset to run poorly.

I have cleaned mine 3 times in the past 6 years ...just under 1,000 hrs on the generator at this point. I believe the schedule on my generator (7500 diesel) calls for it every 150 hrs/annually. It takes a number of extensions on my socket driver to reach it on mine ...20+ inches as I recall. At least once there was a surprising amount of carbon there when I got the plug out.

I did mine at about 250HR'S because of the Performance Schedule. The plug came out no problem. I got a little rust and carbon that blew out and didn't notice any performance differance. I don't know if I'll do it again unless I really want to do something to the coach.

Onan maintenance schedule says to do it - so I do. Their expertise on the proper preventative maintenance is much greater than mine, so I try to follow their recommendations. Have had 5 MHs with Onans and have used them all a great deal - probably average 200 hours per year at minimum, and have never had a problem. Works for me.

J Griff, Is the Onan in the back of the wagon or in the TT?

Thanks for the replies. I may give it a try. Mine is not hard to get at, except that it requires an 8-point socket 7/16 and they are not easy to find.

Thanks for noticing - that was our first RV, three years of use between overseas assignments. The 57 chevy wagon went to Japan and in the 3 years there never got over 35 mph, more often 15-20. Brought it home and threw a rod first day of travel.
