When I dropped the carb into boiling water I should have known what was going to happen. When a float has a pin hole in and has sunk with petrol in thats how I get rid of it by firstly unsoldering the pin hole that all floats have then just warming it a few times will soon empty the petrol, with a cool float I then solder the pin hole up. This is…[Read more]

Just by accident one day found washing powder and boiling it in a saucepan, in several cases the brown sticky mess goes whitish and when dry even small airways can be blown out with an air line. However remove the float before putting into hot water, without thinking one day just dropped a part carb still with the float into boiling water, in only…[Read more]

I would have though the jet would be larger so would go from rich to weak, Think I have a good 24 T carb minus the adjustable bits as they fitted a teens to twenty’s bronze zenith, if you need spare bit could try and fing it.

Now this is a dyno-starter called a USL, book said something like not to use to assist the motor, bet it would climb up any hill with that. Car was a Overland model 71 from 1913

A DC motor just change over the brush wires, done it on a two brush set ups on generators and quite a few old motors and often found wrong rotation for a engine so saving to have a crossed belt often just changed the rotation. A good way to check rotation is just using a 12v battery, even one of the high DC 400+ voltage motors or generators will…[Read more]

I agree with side valve be careful and have it apart, things to lookout for on some mags is the spark gap protecter, if not removed will break a bit out of the insulation of the pickup ring and the odd carbon earthing brush so just ask but don’t touch any part if you are a bodger with poor tools it will only cost you lots. I would say multi metre…[Read more]

I wonder is it to get insurance to be on the road, going back fifty years we never taxed our farm tractors but had an exemption to say done less than 15 road miles a year so was easy back then. Had a reply to say Briggs & Stratton took over Murray to try them,it would be a miracle I would have thought but you never know.

I have posted info wanted on the US Bolens web site. several people have the Murray lawn tractors, this is the web site if it helps. https://www.mytractorforum.com/forums/bolens-forum.18/

yes like Charlie said heat helps, but be careful if its a large lump of cast iron, heat, soak with paraffin or WD 40 and walk away, do this several times is better than loosing it and trying to do it in one hit. Often people try removing the key with an ordinary chisel, it may work if not tight but does harm to the key head, I use a C shape key…[Read more]

some of the linings to start with are very soft and pliable like thick rubber so not a problem, once fitted you can set the cure by heating in a ordinary oven, the longer its left in the harder the lining gets, so once heated it sets to that time its left in and if taken out early will be soft, and no amount of heat after that will make it hard.

That sounds quite a bit, however it depends where you go, just remember with a cone it isn’t a strait strip, but a flattened C so it just lays flat, just try a strait strip of paper to see what happens, of cause you can use brute force. A friend wanted to renew his cone tin-work on his cement mixer, plenty of cardboard scissors and gaffer tape,…[Read more]

On those it makes no difference as long as they don’t slip. more the same with plate types, grease going very gummy isn’t good, I sort out car cone and plate clutches, some are dry others are wet, however the bit in-between can cause thousands of pounds damage, this is because the know it alls change the material as is very critical, some leather…[Read more]

We had a BMB plough mate with all the tools with no diff lock but did have independent oil immersed brakes, it was easy to use, that is until reversing even with a plough on would lift me off my feet and the clutch leaver was then out of reach, needs must and fitted a cultivator depth wheel up front, what a difference as used to go everywhere in…[Read more]

Often people think the two strokes rev higher by the sound, Saab done a 3 cylinder two stroke car in the 60’s and were very torquay and reasonable quick, they ran up to 4,000 rpm at about 90mph, that sounded like 8,000 rpm like ripping canvas but came at a cost of 20 mpg. Auto Union, Mercedes and Wartburg also made almost identical engines.

Believe pre war there was a twin ported large two stroke Villiers.

Someone may have at sometime adjusted wrongly the valve clearance by grinding to much off the stem of the valve, this stops the very crude rubbish compression release from working, it consists of small bump on the back of the cam. Seen this done to worn out engines to get better running they do idle better but at a cost to your fingers being…[Read more]

Going back the 23 years got good backup and sensible helps to a problem, and looks like the new engine might have had known ignition issues and the firm should I would have thought known this and sorted it, and fist engine also had carburettor issues especially at idle, new ones have fixed air bypass adjustments? where as the old were adjustable.…[Read more]

Forgot to attach the bit of info on electronic ignition I was sent this.

David
Here’s a write up on how the Briggs electronic coils work to advance the timing at higher rpms. I suspect your coil on the weak side is out of spec.

“The simple, but very effective, spark control system advances the ignition timing, causing the plug to fire earlier…[Read more]

This is if any one is thinking of updating something with one of the Briggs & Stratton V twin Vanguard as have had over a year in getting one of those engines to run nearly as it should. I have one of the first now 23 year old V twin Vanguard Briggs that still runs as new and was made in Japan and few people know that, to start with the old engine…[Read more]

Poulan Sweden? however brain leaked but I have an idea they made chainsaws.
