Got 89 vip with 2.3. I pumped out the old oil put in some fresh oil with filter. Also new fuel/water filter. Before I did this I throttled it twice and it fired right up. I let it idle for good 25-30 mins. After changing the oil and filter's it would not start. I then toke off the fuel/water filter and had just small amount of fuel in it so filled it up with some fresh gas. And still will only run for brief few mins. What am I doing wrong? Or is there any thing else I need to do? Been on this since this morning and its getting frustrating
