Re: STARTER/SLOW CRANKING, SWITCH TO A MINI HIGH TORQ?
The starter is not the problem. OK, maybe it is to a small degree, go check and see how tight it is, then tighten it down because it's loose. The heating/cooling aforementioned causes the bolts to loosen over time, which will not help the cranking.
I have seen this before a bunch with the 258, and everyone attributes it to the starter, when the starter has been fine.
The problem here is timing and the vacuum advance on the distributor. I'm willing to bet the advance line is plugged or leaking, causing it to not work properly, and the timing is also out a few degrees. If you take it to someone who isn't used to working on it, they replace the starter, then when that doesn't cure it they play with the timing to get it to start a little easier, unknowingly adding to the problem.
So rather than spending a few hundred $$$ on a new starter, check out (I'd just replace them) the lines and re-time it. Good time to buy a timing gun if you don't have one, they're awesome.
