That's a nice looking "M" model. It's the late model with the good wheel clutches just like I thought it was in your previous post. The 10518 was a great deal as well if for nothing else than the good rear wheels. I like the F series mowers. You might want to switch the rear wheels out from one to the other when you price new wheels!! Better yet go buy another 10518 or similar to use for nothing but parts. (wheels) Thanks for the pics. Ya know. That 10518 is in excellent shape except for the scratches on top.

Neal, Congratulations on the two Lawnboy's.

One more note on your particular M-series, it has the newer style Fuel Tank assembly. I'm not sure if yours was part of the intial recall, or built late enough to just have the updated tank from the beginning, but the metal fuel shutoff valve indicates the newer tank. The original M-series tanks had a plastic fuel shutoff valve, and were recalled due to potential fuel leaks. I had my tank replaced under warranty and it was replaced with the style that is on your mower.

I have read notes from M users that still had the original Tanks that had experienced cracks and leaks. So, be thankful that you have the updated tank. Your M looks to be in pretty good condition overall. I use my M every week (and have since it was purchased in June of 1992).

My cousin went to the dealer recently for a carb float for his Lawnboy. The dealer told him the unit was 30 years old and that he should think about replacing it.

My cousin thanked him for his concern and said that if the only part he needed in 30 years was a piece of cork, he would keep the mower.

Nice M-series you found. Good to see that you have the recalled tank. These are getting harder to find all the time! Hopefully the BBC won't give you any issues. Have you changed out the oil in the tank yet?

Thanks guys! I'm home on lunch break to check the thread.

The fuel tank has some writing under it but I have not made it out. I'll have to admit it would not start for me last night so I did all the regular checks and concluded that I had no spark whatsoever so I started following wires (because they are so abundant) and found this strange wire that led to the top of the deck around the chute on top and could not figure out what it did and I soon realized the bag or mulch chute needs to be in place before the mower would start. So thats what I mean by being a totally different setup than I'm used to.

Echoman, I haven't changed the oil yet. I've barelly had time to tinker yet.

B.T.W Where would one put seafoam on the "M"? In the oil? Or in the fuel?

Neal

The wires you are referring at the top of the chute are for the safety interlock. The engine will run without a bag or plug installed, but attempting to engage the blade without one or the other installed will cause the engine to die. This safety interlock actually serves a good purpose. If someone tried to mow without one of the attachments in place, the chute would direct the output directly on the operator.

If you choose to add Seafoam, I would mix it only with the fuel. I wouldn't think it wise to dilute the oil.

+2 for sure Neal. In the gas, not the oil! I gave the combustion chamber a good dose on mine a few months ago, then let it set over night to help lossen things up(carbon) that is. Didn't take long to clear up after I started it, but did get a small drop of black goo from the muffler, so it does work as stated. This stuff is awsome! You'll see positive results from dosing the gas with it too. The mikunis' on these mowers are a bit touchy. Wouldn't hurt you either to throw a small inline filter on it either.

There is a cut-off in the oil tank too. Be sure to keep the oil tank topped off to avoid non-starting issues. The cut-off activates before the oil gets too empty. You might not think it's low enough to cut off but it will..

Well I had some time this eve to do some tinkering and went for the muffler first. I have to Nealize this thing before I even want to run it very long.

I took some pictures of the exhaust port and cleaned it good.
I was pleasantlly suprized that the rings looked free and the cylinder walls look good.

These pictures show how I have good luck cleaning all the carbon from any lawnboy muffler.
You burn it till it stops smoking. I know some may have a hard time seeing this done but I have done dozens this way and none have warped or whatever. It makes those mufflers clean as new.
When Its cool to touch I tap the carbon out and use compressed air to release any bits.
These pics are a little large (sorry)
