'75 MG Midget -- MadGe
« on: November 02, 2014, 11:42:55 AM »
Decided I might as well chronicle MadGe too...


History of what I've done since pickup from Paul.


As planned, had a guy do the front end work that was "in progress". Dampers, full bushing, bolt, and swaybar mounts replaced. Tires, front brake hard lines. Plugs, wires, dist cap. All from parts Paul provided (less the concentric bolt kit needed for the control arm rebuild).


On the way from Roch to St Helena Is., the MC let go (Cumberland MD). Did a replacement in an Advance Auto parking lot. Had to manufacture mounting stuff and some replacement brake line. Around Roanoke VA the engine started to act starved for fuel. Suspected vapor lock due to long durations of high speed driving. Continued to occur with periods of excellent driving until she refused to start in middle-of-nowhere SC. While waiting on tow noticed that the electronic ig was shorting. Fixed that to get home but didn't run right.


After a few days of tinkering did some diag and narrowed it down to spark problems. Called some specialists and they unanimously indicated that the culprit was likely me frying the electronic ignition module. Research suggested that the "stock" ignition modules were no good (no one manufactures a Lucas direct replacement) and most electronic manufactures suggested points for the 1500cc in MadGe. So a 25d was spec'd and purchased.


25d installed and static timed to 8°btdc she fired right up. Did some guestimate timing based on the instructions from the distributor supplier and she was very peppy. Loaded up son for test drive only to discover there were 0 breaks as I attempted a turn. Thankfully there was a long sand area between the bail out for the corner and the water.


Got back to house to find large pool of break fluid where the rear driver wheel had been. "Interrogated" son to find that he had mashed the brakes. In researching how to fix ran into the now infomous "dot3 vs dot5 debacle. As of this morning have dot3 out of system and dot5 in it (but out of dot5 to "finish" the bleed tomorrow).


As of November 2, 2014, that's where she is. Next actions are going to be
1. finish with brake flush/bleed
2. rebuild rear brake cylinders and then flush/bleed again.
3. clean up some electrical stuff
4. fix windshield sprayer (if not fixed in #3)


Interspersed in there will be "take wife to beach".

So after all the fun so far... Are you happy with it still?
Sounds like you bought an old JEEP. LOL
Beach sounds good right now. Cold here!

All I can say is that the MG is a blast when it works. Driving through VA was amazing. The few drives I took here were loads of fun. She's the anti-MLC. Quick. Responsive. Good on fuel.

Just hope she stays running for a while.

Yeah. Still happy.  Just put 50 mi on. Does 70 smooth. Gets Around corners amazingly. Just enough engine to be peppy but not enough to cost me my license.

MadGe was a prop in a photo shoot. The "old paint" was perfect. The wear points just added character.


The fun started post shoot. Noticed there were no brake lights as the son parked her. A bit of "wingman" support helped diagnose the break light switch as the problem. Fine. Wife drover her car so drive home wasn't too worrisome. As we started to leave the parking lot asked son to adjust pass side mirror. After second of silence he handed me the mirror.


Looks like my weekends are filling up fast. A real garage with lights would be real nice now that the days are so short.

Brake light switch and new rear brake cylinders+shoes installed. Did 200mi going through Savannah and other local towns trying to find a mall for the ladies.

Based on fuel gauge it looks like 4 gallons of gas. Only engine work has been putting in a points based 25d and setting timing to 14btdc. I'm not being nice to her with extended 3.5-4krpm sections of highway. I am running ethanol free "marine" gas.

Only problem I'm having now is the standard short stop "vapor lock" due to crapy exhaust placement (design). No signs of overheating but it's cool down here right now. Need to check that as things warm up.

Not much but..

Mirror "rebuilt" with the salvaged parts that came off.

Four runs to Savannah this week. Not a single issue. Set timing to 18btdc to get a bit more bang. Very snappy at all RPM but a bit doggy under 1500. Runs 70mph way too easy. With the advanced timing and a tad rich (still trying to fix that) with LOTS of thin pedal I'm getting 32-38mpg. Not too bad.

Next on the list is routine maintenance. Next big thing is an oil cooler to help summer cooling.

And proof that MadGe is my daily driver (for the little driving I do)

Probably. It's amazing how much smaller that car is once you're actually standing next to it.

For all the "WTF did they do it this way" I've run into on MadGe, I think they (and by they the folks who designed the Triumph 1500cc engine) got the oil system right. Oil drain plug is lowest point in engine when car is level. Oil filter is dry if the engine has been idle for an hour. Filter is easily replaced with nothing in the way than the easily removed air supply duct (you have to take it off for everything). Hardest part has been finding oil. 15w-50 is ... not easy to find.


Arie, you have any relation with Auto Zone?
