9hp Intek backfires out carb badly without choke

Might as well lap the valves while you got it down................. Yes I do see a leak also it's on the far right of the block..... That would be a low compression issue if it was leaking ...........

Is this the area you are talking about?

No sir the area to the right of the pushrod chamber right below the middle.... I don't think its a shadow......

I just looked that area over really well and to me it looks like there was no burning and the gasket itself has not charing etc. I think it was just the picture.

It didn't look like bad burn and I see Briggs stepped up on making the areas bigger on the vangaurds the inteks have only a skinny area between the cylinder and pushrod chamber.... That one you got has a lot of meat on it for sure....

Lap the valves and if it still does it then check the travel of the rockers carefully.... A lobe on the cam might be worn down bad enough to do what your mower is doing.....

I'll post a link in a bit to show you what i'm talking about.........

Oops I forgot to come back and post the link.... Now I am not saying this is your issue but something to think about .....

Also what carb do you have on your engine ??? I am guessing the Nikki Carb Depends on the age of the engine.... The code would tell me that. It's the last set of numbers, the first 2 numbers are the year.....

Those Nikki carbs are finicky......... I have done toooo many of them and the kits are pricey.....
