Make sure the Grose-Jets are screwed down tight and the floats are at the
correct height. I recently had a problem where after ten years of
operation one of the jets vibrated loose and messed up one carb (to put
it briefly as possible)..
Dave Houser had this to say:
>Getting closer to the problem now.
>Took float bowls apart to check measurements on float level. Noticed
>front carb had more gas in it than the back one. Made a mental note.
>Put things back together and took for ride to see if I was still losing
>power and stumbling at 3500.
>Couldn't find a suitable stretch of road to sustain that speed so pulled
>off road and held throttle to 3500.
>Didn't take long. Sure enough problem still there. Car stumbled and lost
>power. Shut down and released hood to check on which carb was the
>culprit. Only saw pool of gas under car between both overflow pipes!
>Started car and from engine compartment held throttle, revving engine.
>Again, short time later, gas pouring out of front overflow pipe, car
>losses power, then comes to life again.
>So, what do I look for? BTW, these have grose jets in float bowls, so
>don't tell me they are not floodable!

>Help,
