okay so I have been having issues starting up after the car being off for a number of hours.I have a walbro 255 pump with an msd ignition and aem ems. I have to try starting 3 or 4 times before it will actually start up. and then when it doesn start sometimes it will idle down and die again. I just figured it was in the timing or in the ignition settings (which I am not sure how to change) so I was going to wait until after I got tuned by mase to see if it fixed the problem. But having to wait due to lack of funds I decided to check the only thing that I could. the spark plugs (denso IK24 iridium). they were all carboned up (not too bad just a good solid layer). I know I am running rich but I didnt think it would effect starting. so I cleaned the plugs and it started up like a charm. only problem was I made a few trips and went home. the next morning same problem. So my actual question is should I go with a hotter plug to burn the extra fuel? any other suggestions would be greatly appreciated. thanks Jon
