So, My carbed, cammed, malloried 2056 has been steller for about 6k miles. Then on a run up to Santa Rosa it started feeling less "crisp" on acceleration, and is popping out the tailpipe when cruising along. Not loud bangs, kinda softly doing it. Getting also a bit of snorting out the carbs on start up. Going to crawl under today and check for exhaust leaks (SS exchangers).
What else should I check? Valves? Timing? Ignition circuit? Also, as an engine wears in and you start putting some miles on it, can it change in such a way that would require re-evaluating your jetting? |

gradual deterioration of power would point me towards a dirty carb, decreasing fuel pressure (maybe due to a dirty filter), weakening spark, or worse, losing compression. did you do a compression check when fresh? If so, do another one and compare.

If so, do another one and compare. You know, I was having hot start problems (cranking, no firing) and found that moving my coil (bosch blue) to the firewall solved it. Perhaps its breaking down. As a complete aside, yesteday morning, I had a belt squeeling, and found I had lost the Alt. adjuster bolt. No gen light warning. I fixed that, and was hoping that maybe i was running rough due to voltage dropping gradually. After running for half an hour, it made no difference. |
