Hi guys, I'm new here. Someone gave me a White push mower with a B&S engine that looks to be at least 20 years old, 5hp, to see if I could get it to run.
It has good spark but won't start. I checked the compression and it only has between 55 and 60 # of pressure. I didn't know if this was enough to run or not.
When I tried the primer bulb, no gas was squirting into the carb. I took the bowl nut off and cleaned it and the bowl and sprayed some carb cleaner through the carb opening and up the main jet. The primer started to work but still would not fire. It would fire for about 1 or 2 seconds with starting fluid but then stop. I'm used to working on Lawn Boys and their carbs are so easy. This thing has so many levers, springs and linkage I'm about half afraid to try to take the carb off for fear of not being able to get back together right. I just wanted to get someones opinion about the compression. Maybe its just too low to run?
Any thoughts or suggestions would be appreciated. Thanks.
PS It was built in 1993
