 Posted: Sat Nov 22, 2014 10:02 pm Post subject: Chugging Bug |
 |
|
| I have a 1965 beetle with a 1600 sp engine. I timed and adjusted the valves to specs. Fuel filter is clean, and choke all adjusted. The bug chugs when you shift gears. I can't understand why. Could it be a clutch problem? It does shutter at take off but not really bad. I do have an oil leak somewhere that pools a little oil down by the pulley. Any help is appreciated |

| What distributor do you have and what "specs" did you adjust valves and timing to? |
My distributor is the 009, timing at 7.5 BTC, valves to .006 and new points not condensor |

What do you mean by "chug"?
The shutter at take off makes me think front transmission mount is failing, bowden tube is not correctly set, or flywheel has cracks, hot spots or oil on it.

The color I believe is pearl white, original. It does have an oil leak and could be getting onto the clutch. |

| Could I have a problem with the choke? I did adjust it and it seemed to run worse after that. Once it warms up it runs better but not completely from the chugging. |

| Are you static timing it to 7.5 degrees? You should use a timing light. Mark the pulley at 30 degrees BTDC (I downloaded and printed a protractor for this). Hook up the timing light, loosen the distributor clamp, start the car and rev the motor up until the 009 gives you full advance. Using the timing light turn the distributor while the motor is revved up and set it at 30 degrees BTDC. Release the throttle, tighten the clamp and recheck. |
I static timed it with a timing light but I did not do the 30 deg BTDC. Is this my culprit? |

| To my thinking, more than likely. What carb are you running. Some people describe the chugging as a hesitation. If you have a light gas pedal foot it might lead to chugging |
I guess what I mean by chugging is that it runs like its cold. It knocks you back and forth in your seat as you get going after a shift. Smooths out soon thereafter |

Not sure if you sorted it but I had the exac same problem as you describe. Mine was a accelerator jet in the carb was squirting onto the side of the carb, rather than straight down the throat.
Look down the carb when you squirt the throttle, it should be a good strong jet of fuel straight down the throat. |

Not to be a pessimist, but you could have a bad cylinder/ or cyl. head.
I could just be that you have a worn out engine with one or more low compression readings on your cylinders. |
