i believe the adjective i used after the valve clearance adjustment last weekend was "purr-y." (IMG:style_emoticons/default/driving.gif) well, that is over. as the tank was very low, i filled 'er up with chevron 92 octane, and threw in a bottle of stp carb cleaner additive for good measure. what i got for my efforts is rough running, hesitance, the occasionaly misfire when cold, and a general feeling of all not right with the world. (IMG:style_emoticons/default/sad.gif)
could it be the gas? could it be me? could it be the pre-flood rains we've been having? (IMG:style_emoticons/default/confused24.gif) it isn't my imagination, so it must have a real cause. i have searched archives for spark plug info, wire info, etc. the gas question occured to me late. any ideas? correlation, or causation? |

My experience is it is not the gas. You mentioned that you ran the previous tank low. You may have picked up some debris from the bottom of the tank and it is now fouling the carbs.
I experience similar symptoms (today and other days too) and this is what I do. I pull the idle jets and blow compressed air through the jets and through the idle jet cavities in the carb body. When I'm done the car purrs and runs absolutely great. It takes off without spitting and sputtering and starts much better. It seems that the good running lasts a few days and then I have to do it again. It takes just a few minutes to pull the jets and clear them. I just had my fuel tank cleaned and sealed and hope that this will extend my pleasure. It's a mystery to me how so much debris gets by the fuel filter but the debris is visible and it only takes a small amount of dirt to steal your engine's joy and power. I hope this helps. Seaside6 |
