Weber DCNF installation < Previous | Back to index | Next>

MSS recommends a metal fuel filter. Also, I learned the hard way to use skookum fuel-line clamps (note solid band) to secure the rubber line -- generic worm-drive clamps may not grip firmly enough, and can cut into the hose if you tighten them too much trying to get them to hold. Since solving these problems, the MSS system has been trouble-free and reliable. I still get a slight stumble when going through about 3000 rpm at certain throttle openings -- this suggests the idle circuit (which controls both idling and low-range running on a DCNF) may still be a bit lean. Going up one size on the idle jets might fix it, but I want to be sure I have a solid handle on the problem before I start experimenting further. When troubleshooting things such as a carburetor installation, it's always best to follow the scientific method and change only one thing at a time!
