Hi Mike,
Your mower is a 1974 model. It has points & condenser under the flywheel. Those parts are stil
available. The fast running condition probably involves the governor that is also located under the flywheel. There is a rod that sticks up from the carb. that goes up against the governor. When
you get it started reach up & see if when you move
the arm it makes a difference in the speed.

What ratio of oil to gas are you using. When you run the recomended 16 to 1 ratio the spark needs to be hot and the plug clean to start up fast. Try running a 50 to 1 mix. I run 100 to 1 Amsoil with no problem at all. Just something to check out. Don't get discouraged - for the most part they are hard starting. You can only get one or two revolutions per pull so pull fast. Also clean the exhaust ports with a wooden dowel or same. Take the cover off the muffler and there will be 3 exhaust port holes to clean. They are always plugged running 16 to 1 ratio.

im no lawnboy mower expert, but i thought they are suggested(by the manufacturer at least) to run at 32 to 1?

BTW, we run ALL 2 cycle equipment at 50 to 1.

you may be right Ohio. I will check. This is what I remember running back in 1973. I'm still wondering about the ratio he is running.

Since he said it could be made in the 70's I suggested he was still running 16 to 1. I didn't check my manual but a quick search on the web popped up that Lawnboy's ran 16 to1 up to 32 to 1 ratio. I will check the manuals tomorrow.
