Intek 12.5HP cranking but not starting fuel coming out exhaust manifold gasket the bolts holding the exhaust manifold on are tight. could a blown manifold gasket prevent ignition?
The carb was run dry as I do whenever done mowing , I drained the old fuel inside take.
The engine turns over my battery has 12.25VDC. 1st I noticed fuel dripping from the bottom of the carbs bowl then I noticed fuel coming out the exhaust manifold gasket which was actuely wanting to start a fire, this is when I stopped trying to start her.
I have a spark tester but not sure if it can be sean during daylight I didn’t see any lighting. When I saw the redness of the fire right at the exhaust manifold gasket I figured shes getting spark.
I always start w/ the choke on,Of course last year spark plug got gas fouled now the brand new spark plug is also gas fouled.
This usley happens every lawn season at first mow I have been getting away w/ just swapping the Spark plug champion RC12YC spark plug but not now. w/ spark plug removed trying to start I see fuel coming out SP hole.Thanks for any advise.
Additionally I replaced the engine 5 years ago w/ same intex 12.5HP been running good probably could use a valve adjustment I just haven’t gotton the hang of adjusting the valves.

update: there wasn't a exhaust manifold gasket, the manifold itself was cracked.
could this prevent ignition bc most of fuel in the cylinder was being pushed out?
luckiely I saved the old engine so I swapped the old manie on. guess I'll buy another spark plug an try again.thanks for advising
