Small Engines (Lawn Mowers, etc.): Mccullough MAC 3200 Model ??600032-07 starts but wont run, carb settings, diaphragms
QuestionI have a mcculough 3200 that I just replaced the primer bulb and fuel lines. It will start but when I give it throttle it dies. I have to pull it many times with and without choke to get is going but it dies everytime. I may have bumped the hi low carb settings and don't know what they are. It ran before I changed the primer bulb also. I really believe these symptoms are related to the carb settings but will get fresh fuel and make sure I have a 32:1 mix tomorrow. I may have used 50:1 mix from my outboard. Any direction is appreciated.
AnswerMany times if the fuel lines are hard/brittle so are the carburetor diaphragms.
Before you sink a lot of money in this unit I would check the engine compression. You should have at least 90 PSI of compression. If the compression is good and you have good spark then I would recommend rebuilding the carb. This consists of replacing the diaphragms and gaskets. I would use compressed air from an air compressor and carburetor cleaner to clean the carb.
If you take the carburetor to a small engine shop they can get you the parts/kit you need and/or rebuild the carb for you.
Let me know if this helps.
