If you've not done so recently, pop the muffler off and clean the exhaust ports. The 10545 is an F engine, so should have an under-deck muffler. I mow with nothing but two stroke Lawn Boys, and my most used one is from 1974 with a D600 engine(one generation behind the F engine). It can chew...

I honestly rarely post here anymore because it's a whole lot of complaining about "kids these days" and a whole lot of holier than thou pontificating from a small vocal group who apparently never do anything wrong(and won't entertain disagremeent with their self-proclaimed expertise). It's a...

Mass produced Swiss watches may hold their value, but few are going to go up. Rolex makes how many Submariners and Datejusts every year? Actually I don't think anyone outside Rolex knows, but it's a lot. Vintage watches are hot right now and a lot of rare ones are appreciating. Even some...

I've bit my tongue for a lot of this thread for a whole lot of reasons, but just wanted to add a comment on this. Under the traditional "credit hour" model used by the majority of US schools, credit hours for a lecture course are assigned for how many hours a week are physically spent in...

I wear a Rolex ref. 16035, a 1980s Datejust with a two-tone Jubilee bracelet, fluted gold bezel, and a "champagne" dial nearly every day. That's the classic "old man" watch now, but to me it's also just a classic Rolex that will never go out of style. It was a gift from my parents when I...

Classical thermodynamics can actually explain a lot of what's happening in boilers and steam engines of all sorts really accurately and really well because-in a way-it was developed to explain what was known and cutting edge at the time. As you said, in many cases, the guys on the ground...

Yes, that definitely is a simplification, but does at least give an idea. As you surmise, they're also just not "turn on and go" devices. With the caveat that I'm working on second hand knowledge and not having actually worked with one, the general procedure is to first start water flowing...

Here's a good video just on how the injector operates This page has a lot of good steam locomotive videos/animations that look at individual components, and really a "modern"(say post 1930s) steam locomotive has so many systems that about the best you can do is have an overall picture of how...

Usually the quick fix in steam is to back off the throttle a bit and it will grab again. You can also flip the sanders on to help, but Ed has stated that he avoids them on the Big Boy. I'm not sure if avoids them means "never" or just "not regularly" If the slip is caught fast enough, there's...

I'm not sure if it's worth going into more detail because it seems that you know far more about how steam locomotives should work than the people who designed them in the first place, but I'll try... In steam locomotive contexts, the "boiler" means the pressurized vessel that holds water/steam...

Sorry but...no... The Big Boy, like basically every other modern steam engine uses "injectors" to put water into the boiler. There are normally two of these-if I'm not mistaken FRA regulations(and just good practice in general) require two separate systems for putting water into the boiler...

Something kind of interesting, or at least I think... Allowed axle loadings on most railroads are a lot higher now than they were in the steam days, but there have been few improvements in the quality of trackwork and in some cases it's actually worse than it was 1950s. There's still rail out...

I took a day off work and chased it through central Illinois is 2024. It's taking a different route and I've debated about going to see it at the end of this week, when it's coming through here again. As great as it is to see, the Big Boy draws crowds like nothing else rail related these days...

Sorry, not trying to stir stuff up, just that I've been repairing watches for a while(and I have single pocket watches worth $5K...I've been collecting for a while...). My point-again-on all of that was that a timing machine really is not a magic bullet to look at/measure the "health" of a...

I have a decade and a half of using timing machines under my belt. I’ve noticed an increasing number of more casual hobbyists having them now. Serious questions to anyone using one: 1. Can you look at a running watch and visually estimate amplitude? 2. Can you listen to a watch and hear...
