Noticed the engine was getting alittle harder to start, it lacked low speed pep and wasn't powering up inclines like it used to. Almost like I got ahold of bad gas. Decided to check the timing out before shutdown and noticed the dist wasn't moving when goosing the throttle. Verified I had vacuum to the dist and my Mighty Vac verified the vacuum advance wasn't working. Like the title says this is the 2nd aftermarket replacement failure in 16K miles. Just like the 6v heater blower switch I only seem to get a couple years use before they fail. Dang things ain't cheap either, especially when you factor in shipping...... I'd almost just go on ahead and swap the engine out now but dang, I ain't ready to take it off line yet.
