[urq] Stumble under acceleration @ 4000 rpm

[donald stellmaker]

I'm at a loss and any possible sources for culprits would be very appreciated.....................smooth to 4000 revs then acceleration gets 'bumpy,' doesn't happen in 1st or 2nd..................just had a new clutch put in, and the clutch master cylinder replaced but this was happening prior to that work...................stumped and getting frustrated.

Thanks, Donnie
