I have the forum link saved on my PC and when I click on it it just sits and spins. I can click on something else and it pops right up. I've even typed in the name and it will do the same on duck duck go or google. I close the link that hasn't opened start all over with a new link and it might...

Oh by the way why is it so hard to get to this web site. It takes me no less than 5 tries everytime sometimes more to get on here. I don't have a problem anywhere else.

LOL There is none. Remember I said I pulled the motor to replace the pan gasket. It's clean as a whistle. Man was I wrong, You have a good eye. I totally missed that dirt until you mentioned it and then I seen it in the pic. That's why I like taking pics when I'm working on something because I...

I will say it runs better than it ever has with the new coil.

Well I got the new coil installed today. Lets see how it works out once it gets hot. I was lucky to find an original coil

Yep that would work or just pour ice tea on it when your taking a break. LOL

I Know what you mean. I'm on a few other forums and that's the way it is there also. Believe me I will be here until the end. Hopefully someone will read my problems and will help them fix there mower. LOL That's why I still have a flip phone I guess. LOL

It's showing my coil will be here today. I will let you know what happens.

LOL ^^^^^^ Yep LOL

^^^^^^^ LOL Your first post in 7 years and nothing was said? Why bother? ^^^^^^^

I hope this next one last as long as the first one did. LOL

I have found a few NOS 394891 in the original B&S boxes. The new style 590781s are a good bit cheaper and seem to be all made in china. That's where the bad one I have now that I bought was made. Most of the time you get what you pay for I guess. Thanks again for your help.

Thank you, I have found a couple of the older 394891 style like what is on my mower now. Man the newer part number looks totally different. Should I go with the older style? Or will it matter?

I don't have the number in front of me but I know it's a champion plug. I will look tomorrow. I will say one thing I regaped the plugs today after reading over the manual, they were to wide and it seemed to run better.

That's interesting. I don't have a way to check both sides at once. But when I checked each one one at a time they both only fired every once and a while.

Hi, Would you have the correct part number of the coil I should be looking for? Thanks

Awesome, Thank you you gave been a great deal of help,

Here's a pic of the motor just because I was there. LOL Like I said before it's clean.

I'll do one better than that what about a pic of the trim tag?

I don't mind I'll go out and look.

Sorry I don't have a link, I bought it on amazon just because it was easy. It wasn't a B&S, I'm going tomorrow to our local mower parts house and buy a real one.

Ok I went out and worked on it for a while. This is about as scientific as I get. It's not as hot here today so I'm sure that's why the times are off from before. I checked the comp cold, the right cyl was 110 lbs and the left was also 110lbs. I went and got my car timing light before I...

It was an aftermarket coil.

LOL I was going to do that but you beat me to it. LOL Thanks

I tried a new coil and it did the EXACT same thing. Is it common to get a bad new coil?

I want to thank everyone for chiming in that has given me some ideas. That's what I was hoping for. I'm going to go work on it for a while and check the compression when it's hot and won't restart. I'll be back later to tell you what I find out. Many thanks again to all.

Are you saying to wash a mower or to not wash a mower? That wasn't clear. I did answer his question by the way. I myself will continue washing my mowers and everything else I own. It's NO different than washing a motorcycle to me. I have a 2013 zero turn that looks as good today as it did the...

Hi, Thank you that's what I was looking for a little input. It always helps when there is more than one person is thinking. {Without the engine right in front of us, all we can do is give you some tests to do .} That's all I was asking for. And I do understand about not having it in front of...

You know I have read a LOT of threads on here about motors not restarting when hot not just briggs, and I have read very few threads that figured out what the problem was. Why is that? Do people just give up? I don't understand. I haven't worked on my mower for a few days as I like to get away...

Cool, I understand. But if I have to keep something running with carb cleaner or what ever for long, I just stop and find out why it's not running right. I work on all of my own stuff myself I don't take anything to a shop. I restored Corvettes for 35 years so working on things isn't a problem...

Thank you, I was wondering about that and thanks for the manual link I haven't had any luck finding one.

I use very little when I do use it. A little goes a long way. But either one doesn't work. I think the next thing I'm going to do is adjust the valves. When I find out what they are set at.

Now that's one thing I haven't tried but I will for sure. Thank you. Would you know what the valve gap is on my mower? Numbers above. LOL

LOL I like that. I always say we need to contact Carnack. LOL

You know I was thinking about what was said about washing a mower. I blow my mowers of every time I cut grass. And I wash them every 3rd time I use them and I have NEVER had a problem with them starting or anything like that. I guess it could be from sitting so many years?

Yep I tried that and nothing. It's not firing at all until it cools down.

Now I did wash the entire mower last fall before I took it apart. The mower had been sitting in my shed for 10 years before I got it out to work on it. Looking for something to do you know. The mower ran and started great when I parked it because of the oil leak.

Thanks for the reply. I took it completely apart last fall to replace the pan gasket. It's clean as a pin as I don't cut grass with it anymore I just use it to pull a trailer. I just have started using it in the last couple of weeks that's when I seen it wouldn't start when hot. It doesn't...

It sure would have been nice if he had posted what the problem was if he fixed it. That's exactly what my mower is doing and the exact same motor.

I have a Briggs 17.5 opposed twin that will not restart when hot. I've changed the coil twice it's getting fuel but today I finally figured out it's not firing. It's a 42A707 motor. Now once it cools off after about 30 min it will run like a top until you shut it off. It starts right up when...

When you do replace the gear and what ever else is worn out be sure and grease it from time to time and it won't wear out again. While your working on your mower why not go over it and grease everything. Your mower will thank you.

What kind of flap? I'd start a new thread if I were you....

Man don't waste time doing that. Just pull the motor flip it upside down and take it apart it's very easy.

Yea oil is cheap but a gallon wouldn't have lasted long as bad as it was leaking. But it would have killed the grass so I wouldn't have had to cut it as much and as often. LOL Oh yea it was very bad you could see where the gasket had blown out once I got it apart. Plus it only cost $25.00 to...

Yea, I was amazed at how simple it really was. But I'm sure it not being rusted at all helped a lot. Thanks again

Update, My gaskets came in I put it all back together and it's running like new now with no leaks. Thanks for all the help. Now to put on a new set of shoes as these are dry rotted BAD. Just ordered all 4.

Not on this one the muffler was bolted to the motor, once the bolts were removed it slid right off very easily. It's a great design.

Well that was the easiest motor I have ever pulled. Nothing broke and it came right apart. Nothing was rusted or stuck. 45 min and it was on the work bench. Another 15 min and it was a part and I just ordered the gaskets and seals. It should be back together next week. Thanks again for the...

Yea I seen the part your talking about also. That was in the beginning when he was taking it apart. It was a rectangle part with a bearing and two races. That would swap the forward and reverse. I don't know about the speed swapping? It would be nice to figure it out just in case someone else...

Well I have to thank you for the video, That is the very best video I have ever seen on youtube. He didn't miss a thing. I believe I figured my problem. Right at the end about 1 hour and 7 min he said they make these trans in clock wise and counter clock wise. Well there you go just as I had...
