Got two separate problems:
1) Muffler back-pressure?
Just got back from the muffler shop today, whereupon they had replaced my noisy rusted muffler and tail pipe with a new muffler on my 1970 Series IIA 88". They really had no hope of looking up what model muffler is supposed to go on this vehicle, because as most of you have found, it doesn't show up in most parts databases. They just tried matching it as best as possible with the muffler that was on it...by sight, so to speak.
This rover has been my daily driver for 24 years and thus I know its every nuance as if it were my own kin...and since driving back from the muffler shop it just doesn't seem right. Perhaps a back-pressure issue of either too much or not enough? Is there any way tell if back-pressure is an issue?? The vehicle seems quite sluggish at the shift points now, whereas it was okay just before the muffler install. They installed a canister-type muffler of the approximate size and round shape. Can a slight change in back-pressure cause that much sluggishness?
2) Wipers and/or wiper motor:
Has anybody had similar problem of the wiper basically being very erractic...slapping BOTH sides of the bottom windowshield sill with every turn and doing so VERY forcefully, and then maybe the next minute behaving very well with a graceful, small arc and then back to a quick over-radiused slapping??? The wiper itself is attached very firmly to the stub-mount, so that is not the problem.
When I take the wiper-motor access panel off, I notice that what I can see of the main shaft drive on the motor turns with regularity and no erraticness that I can derive. The motor itself seems simple and obviously works. Is there ANY way to adjust the damn thing? The wiper slaps both sides of the sill so hard that I worry about knocking the wiper right off the windshield. It is definietely over-arcing, and would probably do a full 360 if it could. Anybody else have similar problems with their late series IIA or series III wiper system (the single wiper motor, not the earlier dual-motor setup)??
