Fuel pump - aircooleds

Poor running due to

mike the van: Having a few probs with the running on my 2.o l A/C, it is pretty standard apart from Twin Dell 36's

Has been running fine, but seems to be lacking a bit of grunt on the hills and the top end has dropped away

Seems almost like when going up a hill it almost shudders keeps going, but usually a change down is needed, temps all seem OK

Any ideas , I have retimed with a strobe to 6 ATDC. But still having problems!

jason k: induction leak?

check inlet gaskets as these are a common fail on dells

mike the van: Seems to be worse under slight load, although I am thinking maybe the induction side as has gradually developed and I didn't use the thick gaskets

orangebooboobearcrew: Could be the start of fuel pump push rod wear - common problem (see my other posts).

This could be starving the carbs of fuel if worn and particualrly when going uphill / under load....

Loads on here about it if you do a search... :ok
