My 69 beetle has a 1641cc engine in it, thats only covered 10000 miles in the 2 years ive had it. In the past 3-4 weeks, after i got it out the garage its been running really lumpy, especially whn accelartaing hard. At around
50 in third if i push it its misfiring like a b****. Any ideas- someone suggested timing- but surely that cant get that bad that quickly can it?
