last weekend my 583 was a bitch to start, after whipping the plugs out and cleaning and warming them she went and was fine all saturday.
sunday morn and it eventually fired, again fine all day.
today thought i'd check to see if it would go ........NO ****ING WAY.......so again i clean and warm the plugs NOPE try the iridium plugs from the 750 NOPE.
i have fresh fuel which is getting in as i noteed the plugs where wet at one point, 2 sets of ngk plugs both giving spark............ SO WHY WON'T IT FIRE
