ok check this idea out

[bigd65]

well the clatter problem aint totally fixed, yes i am pissed. but, i got an idea what it could be. he other day when i had the top of the carb off, i noticed the fuel level was below the slosh plates. you know the plates the keep the fuel so the secondaries are fed. well i raised the float level and it fixed it a bit but the clatter is still there at WOT. well today i was at a buddy of mines and we check the total timing. its 28 total at 3,000 rpms. (8*btdc +20*centrifigal) ok thats text book. well as i was reving the engine, i noticed the fuel filter was not filling up, in fact there was very little fuel retaining in the filter and this was after i let it back to idle. so, here i go again, we checked the fuel pressure and it was about 6.5 psi. right thats about normal. well here is my question. is it possible the fuel pump can be weak and not be able to keep up with the demands of the motor drawing the fuel at WOT. i am thinking about changing the fuel pump, but was wondering what yall thought about ths therory.
