Classic/Antique Car Repair: Gas in my oil..., vw section, piston rings

Question
I have a 74 super beetle, the car will run great for about 10 minutes and then start to have problems before it finally dies.  I take the spark plugs out and have a fuel smell on them.  I can clean the plugs, put them back in and the problem starts all over again.  Nobody in the VW section but I figure an engine problem can be solved by another mechanic also.  Please help.....

Answer
Hi Scott:
Don't know much about VW's, but I will take a stab at it.
Assuming your plugs are not fouled, but have gas on them would lead me to believe you have a choke/auto choke problem that kicking in and flowing out the car. Also, such a problem could be cause by a bad oxygen sensor. Do know if a 74 super beetle has an automatic choke or oxygen sensor, but if it does, check those.

In the subject, you also say "Gas in my oil". That means gas is getting pass the piston rings and mixing with the oil. So, something is stuck open. This is why I'm suspicious of the choke and sensor. But it could also mean the plugs are not firing, so new plugs and possibly wires could cause this.

Hope this helps...
