Briggs and Strattion 18hp
Hello everyone,
First time posting here but have read more information than I thought I would ever need to know, Thanks. I have a slight (I Hope) problem with an older White lawn tractor model Cruisematic GT-180. I got this mower from a friend who got it for free. The gentlemen who gave it to him said he couldn't keep it running so he bought a new one. The engine is a Briggs and Stratton 18hp I Twin. When I got it the fuel line and fuel filter were shot, replaced. Cleaned the tank out. I also had to adjust the magneto so I could get spark. I rebuilt the carb with an Briggs rebuild kit. It had new spark plugs in it. Once I got all this done it fired right up and I have been using it most of the summer. However, my problem is this: If I increase the throttle to where it will cut at a more than crawling speed it will die immediately and not restart unless I loosen the top of the carb and let fuel drain out. It then restarts immediately. I have adjusted the high speed needle valve on the carb many times to recommendations by mower shops but it only helps a little. The mower runs great except for this problem. If I hit taller than normal grass say 3.5 inches or bermuda grass that is 2 inches it will bog down and die with the sympton above. I can quickly reduce the throttle down to idle to prevent it from stalling. My guess is it is not delivering enough fuel when it gets to a certain rpm or load. Many times it will die at half throttle so I don't think it is a governor issue but I could be wrong. Any ideas as to why this would do this. I have tried adjusting the idle speed with different settings on the high speed needle. It is obviously pulling fuel to the carb just not delivering above a specific range of opertation. any help would be appreciated for I have been push mowing the last couple of weeks which is better for my health and even thought about getting a reel mower. Ah well winter is a coming and I just overseeded and patched areas so the rider is actually a little to heavy for the lawn right now. I will probably sell it once I get this problem fixed any how. thanks Marty Underwood |

Sometimes the governor will cause this kind of problem if it is loose or
damaged. You may also have a sticking float/needle valve or even a float that doesn't float (sinks). I would vote for the sinking float since you have to drain the bowl to get it started. Sounds like its flooded. Does starter fluid start it without draining the bowl? "Marty Underwood" wrote in message news:N%M7b.410076$o%2.186640@sccrnsc02...
