I wouldn't worry about it , I have a Massey that's done that for 20 years.
Now the thing is producing heavy black smoke for a few seconds at start up and then at full throttle initiation.
Yeah, not constant, I have replaced filter and did revisit the filter housing yesterday just to make sure nothing was askew, which there wasn't.Try the cleaners first, run it hard. If that does not fix it you more than likely have a messed up injector tip, either dirt,worn or partially plugged. Like soundguy said cheap to check. The pump would be the last step. Fuel improperly atomized will not burn completly. And like was said if it is constant have you checked your air filter? CJ
