1999 Sugar Sand Jet Boat, 120hp, xr2 pump, 1st owner. Auto enrichment system to key start. Start cold, starts warm, last year did it last run of the season, now this year to, it's that inbetween period, no restart, don't smell a flooding condition. reading the book does not do much for me other then change the plugs and bypass the auto enrich system? Anyone able to enlighten me on some other possiblities
