What Rotor Arm

[tobydog]

If you drive a 30+ year old vehicle perhaps you need a certain amount of mechanical empathy....

If you really must have one, at least keep a bug one somewhere in the camper so you can at least get home rather than trying to find a replacement that the nearest garage won't have.

Agreed. It's one of the spare parts I always carry on the van

All I can tell you is that I have had around a dozen vans in with running issues that turned out to be the rev limiter rotor arm. Swapped for a standard one and all fixed. Hence I never fit them.

Yep. My current van had the limiter version fitted. It also had an intermittent odd running issue. Luckily for me, I chose to swap the arm (I didn't know what it was at the time, just thought it looked like the wrong part) before I started throwing money and time at other parts and yes, the issue was immediately solved.

Looking at the service records I noticed that the faulty arm was only a couple of years and 2000 miles old. Load of rubbish, could have ruined our first trip as everything else was spot-on. I can't really imagine how any loving T25 owner could be so lead-footed and inattentive as to thrash an old A/C lump or WBX to death, anyway - even without a rev counter, theres not much excuse for forgetting to change up early enough in a 30 year-old camper, is there?

Drove the van a few hundred miles now and yes i agree, slowly does it ... chug chugging along !!

Sounds beautiful

I certainly don't rev the heck out of mine but if you don't have a rev counter and like Motorhead full blast, the limiting one is wise. For reliability, and if like me you quite like the sound of the engine, you can't beat a bug/bay one.
