Exmark 23 hp Kohler won't run

Mower has sat under a tarp for about a year. It ran fine prior, but I'm having trouble getting it to run. It cranks and turns over fine. Every now and then after I've jiggled electrical connections, it will run very briefly (1-2 sec.) and then shut off again. I don't know if the connections are just a coincidence kind of thing or not. What do I need to do before putting the mower back on service?

Did you leave fuel in it?

Yes there was a little left in one tank, but I put fresh gas in the other. I'm sure there was some left in the lines though. Should I drain them and spray in the carb with some cleaner?

I would imagine any fuel left in anything for a straight year has turned to varnish. I'd drain the lines, run some fresh gas through them to "clean them out", then I'd remove the carb, soak it overnight, reinstall. I'd start there first.

Sounds like you should start cleaning all the connections if you tap the electrical and it runs

Clean the carb, replace plugs, fuel filter, airfilter, oil, oil filter. I'm sure the carb is messed up from the fuel sitting in it.

Nice to see Exmark active on the forums once again. It would be nicer to see you take a page from the Huslter and Gravely reps on the site and be more active in the discussions with possible solutions to problems instead of the canned response you give to every Exmark thread.

OP any update? Have you cleaned the carb yet?

Still struggling with this mower guys. I took a break from it for awhile because business has been so crazy here. We've got constant mowers down, and I really need to get this one going as an extreme back up.

Update:
I took the carb off and took it completely apart. I sprayed the whole thing out with chlorinated carb cleaner to get rid of all the varnish. I sprayed through the jet, cleaned the float bowl, and made sure there were no blockages. Also drained all tanks and lines and made sure fuel was getting to the carb. Put it all back together, and now when I crank it, it will run with the choke on as long as I want it too. The RPM's will bounce and then it will smooth out. Then they will bounce again. When I turn the choke off, the mower will shut off immediately. Any ideas on what to check?
