    Starting SA200 after sitting

    I didn't want to search through all the posts so I thought I'd just make a new post. Need to get my 61 SA200 going to fix my backhoe. I haven't used it for a couple years but did put Seafoam in the tank the last time I used it. I know I need to take the brush cover off and check for signs of mice etc. but what else should I do? I've also read there's a technique for starting these so you don't flood them. It had a rebuilt Mag and a new zenith carb but sometimes flooded trying to start it. Any help is greatly appreciated.

    Dave after doing what you have planed. I would pull the spark plugs, check them out. And spray some WD-40 in each cylinder, and turn the engine over by hand a few times.

    Re: Starting SA200 after sitting

    I have an update. Took the cover off the brushes and no signs of mice but a lot of that fluff stuff that flies around in the fall all over the whole machine and some under that cover. Good thing I took the cover off though as one of the brushes was popped out at a 45 deg. in the holder. I got it back in easy enough but it was shorter than the other brush? Is that common? Didn't pull the plugs but turned it over by hand with the fan a few times then boosted it to see if it would start. Nothing. Pulled 3 of the plugs and they looked good but no signs of gas. Checked spark and only saw a little spark so took mag cover off and it was dry (good thing), then took off distributer cap and sanded the contacts. I think I recall you've had to do that CEP. Played with it for a while and thought I'd have to come back here to get some more advice. The gas seemed a little funky and then a guy showed up that's helped a buddy get a couple SA200's running. He confirmed the gas seemed suspect and was a yellowy colour. I took the tap out and he helped me tilt the machine to drain it. I think the machine was basically ran out of gas the last time I used it because when I put about 2 1/2 gallons of fresh gas in, it started in about 10 seconds and just purred, no smoke or strange sounds at all! Didn't use choke at all. After a few minutes it idled down. I tried to strike an arc and there was a spark but the engine didn't speed up, so I pushed the throttle lever on the R-57 and it struck a bigger arc and then the idler started to work properly. It would take almost a minute to slow down but the idler was working! After that the machine ran great and I got by backhoe stabilizer fixed.

    I forgot how nice a machine a red face is to weld with. I had some old 5P+ 6010 and after setting my heat put in a nice hot up hand root on the tube on the stabilizer bracket. 3rd gear at about 40. Had to do a down hand root on the inside because it was a little awkward to get at laying under the machine. Then I finished welding it up with some new 3/32" 7018. I had to turn the heat down just a touch because my first weld up the tube the rod melted off just as I was about to finish. Turned it down to 35 on the dial and put a nice hot cap over the 6010. It's not a perfect fix but is probably better than the original small weld. I think I'll take your advice and burn a couple rods every month or so just to keep the machine fresh.

    Good idea, keep her in shape. I run mine every week or so. Just fire her up and burn a few rods. I keep some big ones so I can weld in all gears and from 0 to 100%

    Yes, I know it's good to burn some 1/4" every so often to clean it out. I was surprised how easy it started after adding fresh gas and even more surprised how the idler starting working and how nice it ran.

    I run my SA-200s at least once a month. After running some 1/8Ē rods, with the welders nice and warmed up. Iíll burn a few 3/16Ē 6010s to make them work a little bit.

    I 've got a few 1/4" 7018 to make it grunt. The governor was working perfect yesterday. It took a long time to idle down but it did so no problem.

    Your governor is a lot like me. I donít move to well after setting for a while!

    Just to clarify, the governor isn't responsible for idling the engine. That's a function of the idler and if it's slow or lazy that is likely due to the vacuum control adjustment.

    Not sure if you are confusing the two or simply stating two separate facts. My apologies if the latter.

    No problem Duane. I know the governor has nothing to do with idler. The machine was just running great when I struck an arc and grunting like it should although it has a muffler that is sacrilege to the SA200 purists.

    Re: Starting SA200 after sitting

    Dave, I would download the manual from Lincoln's website and the special manual concerning the R57 idler. It's possible the little piece of foam under the adjusting screw just needs cleaned and fluffed up. The screw adjusts the idle down time after the arc is broken. Get her back up in good shape and keep her there. They are very handy to have when you need them. When you strike the arc and they snap up to speed and take the load you know you can Git-R-Done. No lawnmower engine drive gives you that feeling IMHO

    I had it apart last year and I think it's missing the foam piece. Originally it idled down after 25 seconds which was fine. I counted how many turns out the screw was when I took it apart and put it back the same. If it takes a little longer to idle down is OK. The time shortened some after I used it for a while.
