Hi,
My Midas went for an MOT last week, It managed the first 10 miles under A series power, and the rest on back of a transporter. It turned out the rotor arm was the culprit. Mr McDonald (McDonald minis, http://www.mcdonald-minis.co.uk ) was as expert as usual, but this time, waiting 2 hours past his closing time on a Saturday, and then not charging for this time!!!
Back to the issue, he recons that the later batches have this problem, the rivet that holds the metal arm on, can eventually allow the power to break through to the distributor shaft, so the power goes into the distributor, but not from there to the plugs. This is the second time this has happened to me (two different rotor arms). I fixed it myself the first time, but on the hard shoulder of the M8 in (almost) storm force winds, I was not going to take the bonnet off to poke around.
This leads me to a question, where can I get a rotor arm without the offending rivet?
I have look at the Demon-Tweeks catalogue and they have some rotor arms, are any of these suitable?
http://www.demon-tweeks.co.uk/motorspor ... -rotor-arm
At £7.50 + vat, they cost more than the standard item, but they account for 66% of my breakdowns, so it would be easily worth it.
They have two types for 4 cylinder distributors
43/45 D4 and
23 D4
I tried to copy the page from the website, but this is all I get:-
