could be 1987 not sure yet.<br />it runs on idle bad it jumps from 700rpm to 1200<br />without touching anything.<br />if acelerate and let it go it dies when coming back to idle.<br />i have cleaned carburators,change gas mix,gapped sparks plug and still same problem.<br />today i pull the fuel pump apart and could see one of the diafragm cracked (see thru).<br />could this be the problem?<br />i mean i know it is a problem but i guess the question is could it be THE problem?
