Anyone know of a engine tuner in Central Ohio? New rebuilt 2056 engine with
Dellorto, Web Cam, Etc. I have a misfire on number 3 cylinder. It is at 2 to 3 thousand RPM. and it is intermittent. It is on a run stand so everything is right in front and center. I would guess it is in the carb. Brian (IMG:style_emoticons/default/headbang.gif) |

At that rpm on a test stand, an intermittent miss possibly means your idle jets are undersize.
It isn't possible to tune the main circuit without a significant load on the engine. |

I swapped the carbs left to right and the miss and popping followed the carb. So I guess I need a Dellorto guy.
