Briggs ES45 just will not start!! advice please.
Hi everyone,
I have a McCulloch Elite 47 PDE lawnmower with an electric start Briggs and Stratton (looks like a quantum engine) ES45. Here is the problem:
. Throttle lever in correct position to start
. Push primer bulb 3 times as usual
.Turn the key engine turns over lovely, occasionally tries to fire.
. Have drained the fuel and replaced with fresh
. Changed plug and gapped for a new one (same make as what engine run with)
. At one point it backfired through the exhaust
. Had the carb off and cleaned it totally but it did not have any signs of dirt in
. When I remove the plug, it is wet. So tried starting without the choke (after pulling the engine over a few times without the plug) Have also tested the spark and it is good. Prior to removing the carb, I put a small shot of neat petrol in the plug hole, absolutely nothing, not even trying.
When I removed the pull start top to make sure everything was in place a small spark appeared as the steel cover was drawn away from the engine block. I wondered if this was an earthing problem and disconnected the battery. Trying to start the engine by hand proved no better.
There is good compression as it can be started by pull cord or electric start. Very odd and I'm out of idea's. The model engine number is 12770
Thanks in advance.
