Okay so I haven't been very active on this forum for a while.. Work has been really busy (thankfully.) Anyhew, one of my project tractors has been sitting for a while because it needed a battery. I bought a battery, went to crank her up, and she started just fine. Turned it off to talk to my mother who was outside gardening and next time I tried to start it, it would only turn half to one revolutions before quitting. After a few tries, I smelled something burning, and sure enough there was light smoke coming from below the starter. Thankfully, it didn't (and still hasn't) caught fire, but any clue what is going on here? Bad starter? It really seems like it is under some heavy strain trying to start. And not that it makes much of a difference because its not too hot out, but I bought the premium battery with the extra CAs and CCAs.

^ In regards to a 18hp B&S powered Murray GT ^

Thanks!

Yea, I've noticed you were MIA, so you will be summarily hauled up for dereliction of posting!

I'd say the windings are shot and no starter is fried before its time, so I'd say it was its time!

I just fried mine up on the Murray Select. 10 years old and from what I'm told the Briggs opposed twins put a strain on the starters. Glad to hear you are busy at work. So is the Mrs. thankfully. I noticed you have not be around lately, don't be a stranger.................

Oddly, she started up fine today. Figured I'd just see if it would start at all before I tore into the starter..

Kind of nice that it worked.

So I then ran some Sea Foam through the oil and a little in the air intake. Kind of funny watching the plumes of white smoke billow out of the tractor, hehe.

Anyways, changed the oil and she runs as smooth as new. I have high hopes that maybe there was just some sludge build up that I was able to dislodge and clean, instead of needing a new starter.

Until next time,

:greendr:

IF you do need to change starters, you may already know that practically any B&S starter will interchange with that by changing the end/mounting bracket. I would check for excess play in the bushing in that end/mounting bracket. I am guessing from conversation that this is a horizontally opposed B&S twin and they tend to wear the bushing oblong causing the armature to rub on the fields. B&S says not repairable but I put new bushings in them all time.
