try cleaning out your fuel tank and use new fuel make sure tank flows fuel, you said it was parked for awhile, so this would be frist on my list.

but the tank was empty along the stop period and obviously i felt it up with new fuel.
but now i am remembering a friend who has had troubles by the hose cap...

i'll check.

see what color your spark is should be blue/ not red or yellow also run it 15 min then shut off and see if the coil is to hot to hold on to if so replace. its breaking down.

do you think that coil gives alternated problems?
because, as told, the engine goes some time very well and after arrives more or less not over 3000/4000 rpm.

i hope anyway that coil is my problem.
