have u had it running good before or has this happened from the day u started running it...u may need to advance/retard the cam, u could have a really big vacuum leak somewhere, Dry sooty plugs indicate a rich mixture or weak ignition. This causes misfiring, hard starting and hesitation. The recommendations for this is to make sure the spark plugs have the correct heat range, check the airfilter to see if its clogged or a problem in the fuel system or engine management system. Also check for ignition problems....I got this out of my haynes manual that shows different plug conditions and stuff...but thats a pretty crazy setup u have there and will take a bit to get it running good...but when u do...heheheh.ooohh man


got my 78 merc with a 250 I6 and i love it.
