1943 B&S model A engine

I've had this B&S model A engine for almost a year and finally got around to getting it running.The engine was complete when I got it,it looked like someone had cleaned it up some a tried to get it running.When I got into it,the first thing that I found was that it was turning pretty tight,I found that the engine had been put together without a gasket that sets the crankshaft end play,so I made a gasket for that,the points plunger was sticking,probably from old oil so I had to get that free again.Once I got those things out of the way,I tried cranking it and found that the compression felt pretty low,I tried to start it a few times but it wouldn't even putt.I ended up taking the piston out and found the rings were stuck in the ring grooves from carbon,I was able to carefully and with the help of liberal amounts of wd40,I was able to get the rings free.Once I buttoned it back up,it didn't take to much to get this one singing again.To me these old engines are a testament to sound engineering,this engine was built in 1943.It's all cast iron,even the head shroud and blower housing,it weights about 75lbs and produces about 1 1/2 hp,that's probably the real reason why they last as long as they do,while they are a far sight better than the hit N miss engines that came before,they a far cry from the engines that power lawn equipment a such today.

Log saws

Old machinery really amazes me,back in the early part of the 1900s gas engines were all the rage and in most cases were billed as labor saving devices but in the case of the log saw,I'm not convinced that that really was the case.I think the log saws were used mainly to section a tree after it was felled but a few of them were built with a blade that turned so that,I'm guessing anyway,they could be used to cut a tree.If you've ever seen one run they will cut a tree,there's no doubt about that but the time a labor needed to get it to the tree and set up to cut makes me wonder if it was worth it.

Wisconsin engines

One of the reasons that I prefer vintage Bolens tractors over some of the other brands is there use of Wisconsin engines,they used engines from just about every small engine company but they had quite a few of there earlier models that used Wisconsins.Now if you ask people that have been around engines for a while about Wisconsin engines,you'll get a lot of different opinions,everything from love 'em to hate 'em.Wisconsin has been building engines since around 1909 or 1910,they started out building 4 cylinder engines that were used in cars,trucks and tractors.Stutz,Kissel,McFarlan,Brockway and FWD were a few of the companies that used Wisconsin engines.The Stutz/Wisconsin combination cars were front runners in the early years at the Indianapolis 500 and the early Stutz Bearcats used Wisconsin engines starting in 1914.In the 1930s they started building small engines and came out with the V type 4 cylinder that is still used on a lot of agricultural and industrial applications.The engines that they built from the 1930s into the 1970s were big hunks of iron,most weighed 100lbs or more,one of those sitting on a tractor frame does a pretty good job keeping the front wheels on the ground.Bolens was one of only a few companies that used Wisconsin engines and if you find one today,unless it's been sitting outside unprotected,it probably doesn't have much wear in it.I've heard of a few that sounded like they were used hard enough to show wear,were rebuilt and are ready for another 40 or 50 years.

gasoline and small engines

Wow,it's been a while since I've added anything substantial here,I guess my minds already in summer mode!I've read a lot of information in the past year or so about gasoline,it seems to be a big issue for people running older engines and even some new engines.I've heard claims of vapor locking,I've seen a few mowers with rubber pieces in the carb that were turned into a gooey mush or eaten away completely and I've also seen quite a few mowers in the past couple years that the only thing wrong with them was bad gas.When I attended Briggs & Stratton service schools back 20yrs ago they were telling us then that gasoline was only good for about 30 days,after that it started to deteriorate pretty quickly,they recommended using fuel stabilizer and I've used it pretty much since then,especially on my 2 stroke engines because they do sit for extended periods at times.The oil companies do mix gas differently for different parts of the country depending on climate and population,bigger cities where pollution is an issue get a different blend than rural areas so this may not be as big an issue in some areas as others.So the next question is what to do about it?First off don't buy anymore fuel than you can use in 30 days time,if you do have fuel that's getting close or a little over,put it in your car and use it up that way and keep fresh gas for your mowers and other small engines.If for some reason the engine will be sitting for an extended period,use fuel stabilizer,I usually start adding fuel stabilizer for the last month or so that I'll be mowing for a season,that way it's completely through the system and I don't have any issues with starting come spring.One other thing that I've mostly read about is to use an once of Marvel Mystery oil per gallon of gas,I've never tried Marvel but I have used Klotz 2cycle oil with good results.It does lower the octane just a little but you can run mid grade or high test to if your worried about that,for the few extra cents of the cost of gas the benefits of upper cylinder lubrication and a little extra lubrication for the valves is well worth it.In these days of high cost service a little extra maintenance goes along way.

vintage garden tractors

There are still a lot of good,usable garden tractors from the 1960s around yet,if you have the knowledge to fix them yourself a lot of them were parked because of simple things that went wrong with them and people just wanted something new.The Bolens tractors from the 1960s were actually pretty easy and relatively cheap to keep running if you understand points and condensor ignitions.I've found very few that had bad magnetos,most times the only thing wrong with them is that the points are dirty or corroded or there is oil in the box where the points are that won't let the points get a good ground.Anytime that I clean points on an older engine,I take them out and file them to get a new surface on them,then before you put them back in the engine,use some contact cleaner to clean the inside of the box out good to be sure there's no oil residue.Put the points and condensor back in and set the points to specs but before you put the cover back on,take a dollar bill and run it through the points to clean the surface again,the material that the bill is made of works better than anything to clean the points.If by chance you do find a magneto ignition on a Wisconsin engine with a bad magneto,it's very easy to switch them over to a battery ignition using a coil and different ignition switch so even if you have a bad ignition,all is not lost.
