Topic: hesitation fixed (finally)!!!!!!
hello all...thanks for all your help regarding the hesitation
problems my '70 bug has been suffering from for a few months now. It
is now my GREAT pleasure to report the solution to everyone in hopes
that someone else's frustration might not reach the level mine did
while troubleshooting the problem.
Apparently, the adjuster screws on the rocker arms had flattened out
as a result of poorly adjusted valves that had not been properly
tuned by the previous owner. I bought the beetle in texas and drove
it home to kentucky, and we're thinking that the valves weren't
adjusted properly before the non-stop 1100 mile trek home. Needless
to say, that's more than enough driving to cause some problems.
Because of the flattened screws, the gaps in the valves were getting
larger, causing my car to hesitate sometimes (severely at times). We
replaced the screws, re-tuned the valves, and now everything is
running as close to perfect as i've ever experienced.
Anyone currently tweaking and retweaking the carb in hopes to stomp
out a hesitation problem to no avail might want to take a look at
what worked for me. I had no idea the adjuster screws could make
THAT much of a difference, but they most certainly did. Again,
thanks to EVERYONE for all the suggestions, and for making this site
such an invaluable resource for VW enthusiasts like me!
