Weber - Air filter soaked with Fuel

[haynes]

Just took my K&N air filter off to clean and the bottom section is soaked with fuel. Theres 2.5" ram pipes on there, a 4" filter. Cam is a 296.

Wondered if it comes from over doing the pumping to start it up, i probably pump the throttle at least 10 times. Or fuel stand off because of the cam.

Anyone know what causes this?

I would be concerned if the filter was soaked with fuel. very concerned considering the location of the fuse box....

I dont know what the problem is but you have a huge over fueling issue, or a leak, the suck through of the air into the carb would normally dry the filter.... hope you get it sorted and keep a fire extinguisher on hand....

Ten times is probably a bit much - I think twice will do it.

I would take the air filter off and have a look at what is going on. You will then see if it is just that you are over pumping. On my mini (same cam and 45 weber). Only found I had to pump one or two times and it would start. I never had the filer soaked with fuel, so its probably not the cam.

i only pump mine twice anymore it floods and is a pain to start

[Chuggaboom]

yeah twice is enough to make it start, even in the winter...needs a little choke to continue going afterwards tho.

has it been set up on the dyno ?...worth while after spending a good wadge on pucker bits for an 85hp+ ATW motor IMHO.

Fuel stand off is most likely. If you wet it from over pumping on a cold start the fule would be drawn in and eveaporated after a few seconds. Had similar problems on a few hot cammed engines.
