have a briggs model 286H77-0121-E1 serial number 020624ZA. engine will not stay running. first solenoid was bad, replaced carb with aftermarket carb. mower will for few seconds. did compression check only 45 psi, getting spark. replaced spark plug. so not sure if due to low compression this is causing mower not to stay running. any advice would be helpful
thanks

The 45 may very well be your cause. A leakdown test would be a better indicator were there compression is going. Could be valve or head gasket related on the Intek single.
