I am looking at a 1948 LA to buy. It has mag on it. There is no spark on #1 spark plug. What could this be? crack in cap or what else? Checked wire and was all the way in cap. Can you get parts for mag yet? Also what oil pressure should it have after warmed up about 1/2 throttle. It is about 10 psi. Seems low to me.
It doesn't smoke. Thanks! DCPULLER

If just #1 has no spark, very carefully remove #1 wire and switch with another about the same length and see if the no fire plug moves. If it does its the wire. If not, switch the plugs and see if it moves, if it does change the plugs (don't use Champion, they are now making junk. AC work well for me). If the wire and plug trick doesn't resolve the problem then dig deeper. Plugs and wires are usually the culprit before a mag on a tractor that has set a good while.

The mags often just need the points cleaned. If that doesn't work, the primary wire from the coil to the points may have rotten insulation and be shorting out, pretty common. Crank the tractor with the cap off and watch for spark at the points. The base mount magnetos are very good and usually fixable, but no parts are available. The oil pressure sounds pretty low, you might wan to try another gauge.

Crack in the cap--stuck or worn brush in cap--carbon track (could be on the cap or the rotor) -- or a bad wire. hth

A 1949 LA was my first Case and I LOVE IT! It is a horse of a tractor. I have about 40 PSI on oil. I am under the impression that mag parts can still be found with a bit of searching.

my 48 La has 40 psi at half throttle and 25-30 at idle ... I had a local guy look at my mag ... and fix it so I'm guessing there are parts ...

I sure like mind ... it doesn't have turn brakes.. it was and option .. just a PARK Brake...

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul ... [Read Article]
