Hard as in compression, or hard as in not getting fuel/flooding?

it has got a little better since this video , i changed the spark plug to one with a shorter nipple ( i dont know what its called !! lol ) now i dont have to take out the sp to turn it over, but its very slow until it fires once then it goes fine

Does it still give you this much trouble when you start it cold?

this is only when starting cold, once its warmed up its like a little kitten..................................................if that kitten was a chainsaw

Your cylinder doesn't have a boss cast into for drilling to add a decomp. You'd have to switch to a 288 cylinder then drill a hole in the top cover. Or if you were willing to sacrifice a little performance, you could shim the cylinder and increase the squish to lower the compression.

Also another option, if you are comfortable with your own modification, you can cut a relief in the top of the exhaust to bleed some starting compression off, it wont have an affect on your performance (Or shouldnt anyway)
