Can someone please tell me how to remove this thing from my 1954 TEA20 without damaging something? I can remove the two 1/2" nuts on the studs at the bottom of the mounting flange--actually, the studs themselves come loose--but the housing won"t separate from the block. I believe that there"s just a gasket in there and that the housing extends a bit into a recess in the block, but I could well be wrong. Do I just need to "persuade" it in a particular manner, or is there something I"m missing?

Bob. I installed a Pertronics Igniter and HV Coil in my TEA20 (also my Jaguar). The improvement in starting, idling and running is stunning - with the added bonus - no points to adjust, no condenser to fail, no rotor or cap burning and the spark plugs should last forever.

It is really satisfying when one gets an old engine to run like new!

Should just slip out? I seem to recall a sealing ring but that should not be holding it.

Sure didn't slip out. Must have been in there since August, 1954 when it was made. Anyway, after more whacks than Lizzie Borden used, it's out now, cleaned up, tuned up--and yes, it did just slip back in after cleaning. Tractor now runs well. Thanks. Bob

Persuasion. The two nuts you mentioned are all that secure it. It is easy to break an ear off the flange, so be gentle.

Thanks for your help with the distributor. I needed to take it out for a tune-up because the fellow who installed the home-made loader came so close to the block with the arms that I can"t get my head in there to see what I"m doing while the distributor is in the engine.

Moreover, I wanted to do a tune-up because, despite a rebuilt carb, new rotor, cap and plugs, and lots of other fooling including new wiring and ignition switch, all winter I"ve been needing to heat the carb with a heat lamp for 10 minutes before the tractor would start.

Well, I got out there today (only about -10C) and took a whack at the distributor. Took about a half hour of whacks, in fact--but gentle ones. Out it came, and I was able to change points, etc. Interesting note here: whoever last changed the points retained the fibre washer that would have insulated the old-style moving point from the stationary one, with the result that the new-style points were misaligned by about half of their diameter. Was it any wonder that they were burned beyond recognition and the tractor was hard starting?

In addition, as I worked I found that the carburetor mounting gasket had hardened, and air was leaking in all around it. I suspect that this was the immediate cause of all my problems, as I just was not getting enough gas to the plugs until I practically boiled the carb. Hard to find, easy to fix; just look for gas falling down from the carb flange.

AND, the little spring fell off my choke. Re-attaching that made a real difference.

ON TOP OF ALL THAT, my good ol" Lucas plug wire connections were badly corroded, and it"s a wonder that I was getting any spark at all.

Anyway, it now runs, and runs well, despite the Lucas electrics. Too bad, Prince of Darkness!

Thanks again.

Thanks. It's around -20 this morning, so I'll wait a bit till it gets warmer out there (no workshop), but I'll give it a whack then, even if I need a BFH (just kidding; don't want to break my ears):-)
