I'm trying to get a Toro 200 (Model #38020) running. I've put fresh fuel, new plug and a carb repair kit. The carburetor was soaked for 8 hours gunk carburetor cleaner. There is spark at the plug. What should the idle and main jet screws be set at? Right now there 2 turns for the idle and 1 turn for the main. I was able to get the engine to run just a short time by leaving the choke out a little.

Main jet should be out another 3/4 to 1 turn. Crank up and adjust idle enough to keep running, then adjust main jet to run smooth at half throttle. Idle back down adjust idle jet till smooth, turn main jet out 1/8 to 1/4 for power, may need more or less as load veries

Joe, page 18 in your manual tells you what to . Drain the fuel from the tank and carburetor by performing the following steps: A. Loosen the fuel-tank cap. B. Unscrew, but do not remove, the small screw on the side of the carburetor fuel bowl (Figure 33) until the fuel begins to drain from the carburetor. Drain the fuel into an approved fuel container. Important: Do not remove the carburetor bowl bolt on the bottom of the carburetor. Figure 33 1. Carburetor bowl bolt-do not remove 2. Small screw on carburetor C. Wait for a few minutes until the fuel has drained, then install the fuel cap and tighten the small screw on the carburetor. Note: Use a handheld Phillips screwdriver to tighten the carburetor screw. Over tightening the screw could strip it and cause leaking. 5. Dispose of unused fuel properly. Recycle it according to local codes, or use it in your automobile. 6. Remove the spark plug. 7. Squirt 2 teaspoons of oil into the spark plug hole. 8. Install the spark plug by hand and then torque it to 27-30 N-m (20-22 ft-lb). 9. With the ignition key in the OFF position, pull the recoil starter slowly to distribute the oil on the inside of the cylinder. 10. Disconnect the ignition key from the lanyard and store the ignition key in a safe place. 11. Clean the machine. 12. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. 13. Tighten any loose fasteners. Repair or replace any damaged parts. 14. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure. The first link is a download for your manual. Check the attached links,instruction and guides, Good luck

check and make sure its getting fuel. when trying to start, spray some engine starting fluid in spark plug hole. just a little bit. replace the plug then try to start it. if it starts then quits then its a fuel problem. fuel not reaching engine. good-day !
For the easiest solution, try running some automotive type fuel system cleaner through the machine (added to the gasoline; not straight). Find some Chem Tool Berryman B-12 at the auto parts store and add 2-3 ounces in a gallon of fuel or 1-2 ounces in a half gallon. The solvents in the cleaner may aid in cleaning a dirty carburetor. You may want to drain the fuel and remove the carburetor bowl and clean it out as debris may be there, intermittently clogging up the main jet in the carburetor. Water will settle there too.
Try taking off the fuel bowl and check for debris or ice in it.If there is hardly any fuel in it you may have a plugged or pinched fuel line,try blowing back through it[might get a littl gas in your mouth],turn off the fuel and remove the line at the carb and the tank.If niether of these pick up a new spark plug and try that.
Fuel Starvation - Float Bowl Carburetor
1) remove air filter assembly
*be cautious of tearing the mounting gasket. If it does tear, you HAVE to replace it. It is part of the priming system
2) remove the float bowl fastener. This is the main jet
3) carefully remove the float bowl, the rubber o-ring/gasket will not be able to be used if it is removed, you WILL have to replace it
4) using a spray 'carb cleaner'
spray up thru the center of the carburetor
spray and clean the main jet with cleaner and 'tag' wire
(tag wire is very thin, and can be used to clean the hole in the center of the main jet)
5) clean any debris from inside the bowl or carb body
6) re-install bowl and center bolt, air filter assembly
*if you need gaskets, your Briggs dealer can supply. The kit is cheaper than individual gaskets, and all the parts needed to finish the above repair are in the kit.
It sounds as if the gas cap may be clogged. It must be able to breathe so that the carburetor gets the proper gas flow. Does it run for about 10-15 minutes? If so, this is more than likely your problem.
