The "Brass Nut" holding the carb bowl on is the Main Jet. There are a couple TINY holes in it. At least ONE is clogged. Use a piece of wire like found on the tie for a loaf of bread to clean the hole.

Thanks for all the replies! This is our first house, not our "forever" house. We are planning to finish the bath update so we can put our house on the market within the next 8-10 months. Then hopefully we'll be in our "forever" (or at least for a long time) house. :) The tub in the master is somekind of old, original cast iron tub. So I know it will be a pain in the butt for our GC to remove! I'm not much of a bath person except for occasionally, but my hubby likes to take them a little more than occasionally. Really this update is to make our home more attractive to potential buyers and hopefully secure us a fast sale. The master is one of the only things we haven't updated in our home, and we're not planning on spending a fortune. What I DON'T want to do is spend this amt of money period, and then wish I had done the tub. It's in really good condition, but it's so narrow and shallow. I wanted to potentially put in a deeper, wider one, but the walls are an issue. The non-plumbing side is my husband's closet, which is the same size as mine (not very big, but a "walk in," which is the plumbing side.) Moving a wall is an expense I'm not willing to undertake, so that's why I was wondering if we could hack into the wall just a bit where the tub is against my husband's closet. I havent talked about this with my GC yet. I'll do that this week. But y'all have seen that done?? Removing the tub and taking the time/money/effort to create a big walk-in shower is not what I wanted to do. We do have another tub in the hall bath, but not having a tub in the master might make someone not want our house. It's all about resale at this point! At the lowest remodel cost. :)

jean you have provided a nice little story but very few facts. this townhouse is a rental unit? what size living space? what size, brand, model,age of outdoor unit? it is true that heat pumps' supply temp is not as warm as supply temp from natural gas furnace. when was system last serviced? when was filter last looked at and changed? I would invest in a cheap digital thermostat-you can purchase at Lowes or HD. Take some supply readings at various supply registers in your home, note the time of day, your thermostat setting, and outside temperature. I would set your thermostat and leave it alone-no setbacks. of course you realize that recent weather has been anywhere from 10-15 degrees below the normal winter average. Post back with additional info. IMO

Thanks for your comments, everyone. I have been going non-stop since I posted this, with 2 soccer games, a baby shower and a kid's birthday party on Saturday, and my son's First Communion and ensuing party on Sunday. Thankfully, my in-laws made the ham and a fantastic lasagna, along with eggplant fritters for the party yesterday. I made a ceaser salad with homemade ceaser dressing, Sol's honey rolls, shrimp cocktail, pineapple upside down cake and Amish Friendship bread. My mom made insalata caprese and a blackberry cobbler. And I purchased frozen Torta Stella from Costco as an additional appetizer. We had 17 adults and 4 kids. Everything turned out so tasty. Nothing quite like a homemade lasagna from an Italian mother-in-law. And when I get her recipe for those eggplant fritters, I'll be sure to share. They were inhaled! Nancy
