I had a similar problem with my 425... The carb probably does need an overhaul, not very much trouble if you are mechanically inclined...the accelerator pump seal you will probably find dry rotted, causing that hesitation, and these fuel pumps have a problem with a check ball to return excess fuel at idle... you should probably throw one of those on, too...they run about $35...also be sure to clean the secondary rods when you have it apart! Let us know how it goes!
