I bought a 1975 Lawn Boy Deluxe 5239D.It finally started after about 20 or thirty pulls.It was very dirty,gas tank clean inside.I cleaned it up and took the carb off and cleaned it inside and out sense it was sitting for about 10 years.
It has good spark and it is priming,but it just will not crank.What can be the problem?I put everything back right in the carb.,cleaned all the holes.
I,m at the end and don't know what else to do.
Please help.
