I think I've finally diagnosed a little problem that I've been grappling with for a long time which would account for a loss of power under load.
I don't know why it's taken me so long to notice but after changing my fuel filter today after a particularly poor run I noticed that there's an awful lot of air getting into the line somehow.
Naturally when I changed the filter I ensure that all the air was pushed out by the weight of fuel and also that the hose was tight and clamped where appropriate. Nonetheless, at numerous stages during the journey I could look down and observe an almost empty fuel filter. This was especially evident when it coincided with occasions of poor pickup.
So I'm wondering where I should be looking? Tonight I shall blow compressed air back up through the petcocks to see if either one of those is blocked but I honestly doubt that as there's a reasonable strong flow towards the carb. Is there any way it could be coming back from the carb itself? Should I be checking the float or could a slightly loose slide be the culprit?
Here's the setup as it stands. Any tips or ideas appreciated.
