Engine Woes

[whale]

Willy.....just and update in response to your inquiry on my other post. I have been away on vacation and motor has been untouched. On Wednesday I went by and checked a few things. I noticed the primer bulb all sucked in but after sitting 2 weeks that might be normal?? Anyway, I put on a new one. I also checked the vent line and it seemed OK. I checked the inline fuel filter that is on the motor and cleaned it. It is basically a conical screen that filters out particles where the fuel line enters the motor. There were a few bits in there but nothing that would obstruct fule flow. I took her out for a short run and it ran fine for about 20 minutes but it is tough to know as the problem had cropped up both times after running for a while.
