Here is one for all the techs.
The engine is a Briggs model 42A707, code 1238-01.
18hp.
Engine starts up and runs good for about 15 mins then starts running bad like running out of gas then just shuts off.
Have to wait half a hour to restart. Then only runs for maybe 2 mins.
Carb and both coils replaced and still does the same thing.
But now sometimes can not get it to start at all.
Took spark plug out and grounded it next to the plug hole to check for spark. It starts right up. Put plug Back in and no start.
What's going on?
