    Re: Petronix - Pros & Cons

    I'll have the new heat shield in the morning with all new gaskets. I should have it running again by Sunday AM as I have a million places to go tomorrow. Will have ther esluts & new pics by Sunday night.
    Then we can re-talk about the Pertronix issue but at least this will put to rest whether or not I have a problem. (with my car)

    Re: Petronix - Pros & Cons

    So far this is what I've done.

    New Wires
    New Plugs
    Adjusted the valves (after my rocker was off and fixed)
    Points, cap, rotor & condensor are all new & fine.
    Timing was set 10 static

    Did I miss something?

    Still running a little rough at low RPM and I stopped working on it while I was still sane. It was hot as heck in the garage last night and working on a hot engine did not help matters any.


    I think it might be carb related because when I increase the rpms just a bit over idle, she runs real smooth and responsive. I'm going to have to get some SU books or a video and set these up correctly.

    Sounds like it just might be an air leak to me.

    Re: Petronix - Pros & Cons

    Weirdest thing. Got home from work and fired her up. Ran like crud. Sputtering & backfiring something fierce. Adjusted the mix still sputtering & backfiring but better. Hoped in and tried to drive off. Bogged and bogged and about 200 feet later I was banging a u-turn heading home.
    Tried tweaking again and went out again. Better but non-responsive. I got about 3 blocks away and went into a parking lot to see what was wrong pulled a hard turn and something kinda poped & she roared to life. What amazing power this little bugger has now. Went out for a longdrive & it was only idling a little high.

    Felt like something was clogged and I must have blown it out or something.

    No bogging chugging or rough idle. Purrs like a kitten.

    Don't know why but very glad that is is working fine. Came rushing back home, called the mrs. to the driveway and she got in. Took her on a very fast and twisty run. I looked over and she had a smile on her face. When we were done she told me that she really enjoyed it. That was the first time she has ever been in an MG and after 20 years of being with her, and my non-stop banter about MG's I finally got to give her a ride!

    I hope this is not a blessing in disguise and tomorrow is a different story. I'm off to get her first inspection and want all to be well.

    Mended itself... that's almost scary - might have to rename her Christine [img]/ubbthreads/images/graemlins/smirk.gif[/img] Still would be a good thing to know what happened - in case it happens again.

    Re: Petronix - Pros & Cons

    Fired her up this morning without the choke and ZERO problems. Just gave the office a tour of it with the old Q&A. Gee oooh ahh. Not one person has ever seen an MG.

    My guess it that it was either something in my gas lines which I still need to replace. Or that Dashpot piston problem I had. Either way I am glad but I start my vaction today so it's gonna sit awhile.

    Re: Petronix - Pros & Cons

    is it because you redid the spark plug wires & got them in proper order?

    Don't think so, he said it coughed and bucked then all was ok. I think it may have been the tenents in the exhaust pipe.

    [/ QUOTE ]

    Possible, if the leads were crossed and the plugs were fouled, getting the wires straight helps but you might still notice trouble until the plugs burn themselves clean with the proper firing order. Sometimes fouled plugs come back, sometimes they don't.

    Re: Petronix - Pros & Cons

    Tony, I never changed the wire order. I had my own system for knowing where they go but I took them off about 3 weeks ago so my aged mind kinda vegged for awhile. My post as to where they go was an in case of.

    When you guys talk about something in my exhaust, what might you be referring to? Banana's?

    I am running very rich right now so I will take care of that as soon as I return. I will also do an other oil change and check the pulgs. I ditched the autolite &amp; am running AC Delco to give them a whirl. Parts guy did not recomment the platinum, 1, 2 ot 4 for this car.

    Re: Petronix - Pros & Cons

    coulda been a mouse, a nest, a potato, something rusty inside the muffler that was blocking the exit and burned through (kinda unlikely) who knows....

    you don't have a catalytic converter so that's not it.

    do you suspect someone coulda tampered with it?
