Hello, I have a FSM that started within 2 seconds when I bought it several yrs ago, now it won"t start without a shot of either (I know). I only ran it about two hrs all of last summer, would"nt start this yr till I gave it a shot. If it were an old v-8 I"d describe it as only runnin on 7. I ran it at full speed up and down the road today for about 45 mins with 4 gallons of fresh fuel in it, seems to run good when under pressure (getting up to speed) and then it has a consistent miss, also when ideling. It is putting out white smoke. When I pulled into the driveway after trying to run the bugs out of it, it almost stalled, kinda like it was flooding out. Any input will be much appreciated.A neighbor is a diesel mech but can"t look at till a week from tomorrow, just wanting some input till then. Thanks in advance.
