USPS is currently backed up. Expect your orders to be delayed up to a week. This should clear up after the holidays and go back to normal.
Most H-Series carbs are kept in stock and ship within 1-3 days, however there may be some delays during the holiday season as inventory is moving fast! Custom and 4T carbs will require a 5-7 day build time before shipping. Please inquire about availability if you need something in a tight time frame. Otherwise, your order will ship once items are in stock.
