but getting the front cover back on the machine can be a little tricky.
TORO CCR 3650 INSTALL
Install the New Primer Bulb Most of this part of the repair involves simple reassembly. Pull the old primer bulb off of the base so that the base can be reused. The primer assembly is made up of two pieces, the soft rubber bulb cap and a hard plastic base. Separate the old bulb from the primer base. Use a pair of pliers to press the primer tabs while pushing the assembly out of the plate. In order to press the primer assembly out of the control plate, there are two tabs that need to be pressed inward. Now that the control plate is completely free, turning it over to access the back of the primer assembly is no problem. It may take a little longer, but it poses less danger to the line. Instead, try using a flat head screwdriver to gently push the line away from the primer. It's risky to try to pull the fuel line out by hand, because it may easily break the line. It will take a little more work to get the primer fuel line out. Remove the ignition wires by pulling their attachment clip out by hand. The control plate still won't be able to turn over because it will still be attached to the machine by a fuel line and a pair of ignition wires.
Separate the ignition wires and the fuel line from the control plate. While lifting the control plate away from the machine, the choke lever must be carefully threaded out of the carburetor.
The back of the snowblower's choke lever attaches to the carburetor. It's time to lift the control plate away from the snowblower, but this has to be done carefully. It may take a little coaxing to get it away from the handle bars. Use a wrench to remove the two handle bar screws, one on each side of the snowblower. And two handle bar screws hold the front cover to the machine. The front cover also holds the control plate down. The cover will still be attached to the snowblower's starter rope, so you will have to wind the rope around the handle bars to keep it and the control cover out of the way during the remainder of the repair. Now the control plate cover can be lifted from its position. Next, remove the ignition key from the control plate cover. To remove the control plate cover, first remove the three fasteners that hold it to the control plate. The first step in removing the control plate is to first remove the control plate cover. Most Toro single stage snowblowers have very similar designs, so these steps will apply to nearly every Toro single stage machine. This is because the primer assembly must be pressed out of the back side of the plate. The control plate has to come off of the snowblower in order to remove the primer bulb. Check out the demonstration video as an additional, visual repair guide. This repair can take less than ten minutes and will save a snowblower owner a handful of money. Simple tools and a little dismantling are all that is required to replace a snowblower primer bulb. But I think I can do better by replacing the carb and perhaps the muffler.Replacing the primer bulb on a Toro snowblower is one of the most common repairs for this machine, and luckily, it's a repair that snowblower owners of any level of repair experience can handle of at home. I understand the Toro's are notorious for noise and oily exhaust odors. It runs reasonably well but surges and does not idle smoothly. Last fall I replaced the auger belt, fuel lines, fuel filter and spark plug, cleaned and lubricated it thoroughly and repainted the bucket interior and side panels. It's about 5 years old and was lightly used but not well maintained. If it is equipped with the plastic carb as you suggested I will replace it with a metal carb. I will take the Toro apart in the spring and inspect the carb. Sounds like a similar issue with the Toro. The Thermoquad was a piece of junk and was prone to vacuum leaks, fuel leaks and warpage. I remember that Carter manufactured an automobile carburetor in the 1970's called the "Thermoquad." The concept was the astic bowls would keep the fuel cool for better performance. If it runs well otherwise, you can cheat the system a bit by installing a fuel shutoff inline. I've learned that leaking when left to store is one major complaint. What's the prob with your current carb? I actually don't even have one of these machines (yet), but have been looking to get one for a year, so I've done some research. The plastic carb can be found, but they leak eventually (or even new). One was the cheapo black plastic version, then they upgraded to a metal one. Summerwinds, They came with 2 different carbs.
