The flywheel will last about 5-10 years with the using 12V. I have never had a starter fail under these conditions. the engine starts so fast, it is not engaged very long. If you try doing the change to 12V flywheel, you will have to machine the bell housing. The 130 tooth flywheel is bigger in diameter. If you go this route, use and automatic starter. They do not need the bushing in the bellhousing. There are 2 different crankshafts for the 1500-1600cc engines. the difference is how the flywheel mounts. The step on the end of the crank is deeper for the 12V flywheels. A 6V flywheel will work on a 12V crank, but a 12V flywheel wont work without some machining on a 6V crank. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
