Had the 914 out a couple times this weekend and noticed some hesitation while at light throttle cruising, say at like 25-30mph in 3rd.
I just recently did a valve adjustment and checked timing per the manual, had to clean up the points a little bit as one side had a little bit of a 'tit' starting to grow. Other than the hesitation it seems to be running well still, maybe a bit on the warmer side compared to what it used to be? (Also first time out this summer, ran it a few times this spring when it was nice and cool) But it has good power, and no audible changes in tone. What should I be checking first? Timing looked like it was right on the mark with vac line off and at about 3-3.5k rpm so I don't *think* that's the issue. |
