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. |

The general rule-of-thumb I've been told (Chris Foley) is always keep it above 3000 under load.
That follows my anechdotal observations of the effects on CHT. Any time it's a hot day and I'm "lugging it" below 3000 the CHTs get into the high 300s. I really don't like that: http://www.914world.com/bbs2/index.php?sho...mp;#entry377466 |

I had the same hesitation issue on our 73 2.0 with new TPS. Needed to pull the distributor and service/rebuild. |

I'd pull the distributor, disassemble, clean the old grease, re-grease and put it back together. You may just have the disks sticking in the distributor. Chris |
