Choke Adjustment on Onan Generator?

Our MH has a 7000 watt Onan Marquis on board. Great generator! and has more than enough power for everything. Runs like a swiss watch and starts easilly when it's cold. The new Yamaha 2000 gets most of the use, but the big Onan always gets a little exercise each time we go camping.

This is something I've dealt with since getting the MH and it's never been a big deal, but I thought I'd post here and see if anyone else has had the same issue.

After it's been running for a while and is up to operating temperature it doesn't re-start as easy. If I go under, remove the air filter and manually hold open the choke butterfly it starts right up. Altitude knob is always adjusted and has little effect on starting anyhow. Air filter is clean.

Does anyone know how to adjust the choke on the genset? I've got manuals galore and trouble shooting guide also, but nothing that addresses adjusting the choke.

I have to admit I'd like it if my choke opened a bit faster too.. How to make it happen I don't know.

When I crank mine up it runs rather rough for a few minutes.. I started it Monday from the generator instead of the driver's seat.. It very clearly was over choked.

I scanned the info for my 4000w unit, maybe it will help.

"After it's been running for a while and is up to operating temperature it doesn't re-start as easy. If I go under, remove the air filter and manually hold open the choke butterfly it starts right up" Maybe a simple mixture adjustment is in order? Mine needed that, the PO had it way off.
