Mike,
Good to know the Dak is running good again. Sunday is going to be my day
with the Dak. I am going to replace the dist. cap, dist. rotor, spark plugs,
fuel filter, pcv valve, and do a thorough cleaning on my QuickD TB with
Gumout's Throttle Body and Intake cleaner. I know without a doubt I need a
new timing chain/sprockets, but just dont have the time right now. I
actually think I am going buy all the parts and just have a shop do it. Not
sure yet though. Was that 1/2" slack on the stock 190K timing chain?
Mine has 131,500 on it now, with the stock timing chain. Thanks.
