This B&S 5 hp model 130200 engine is on a Roto-Hoe Cut'N Shred Shredder, Model 500. It has been sitting idle for more than 10 years. After trying to start engine with no luck, even with dribling gas down the carb, I did compression test. Could only get 30 lbs. Popped the head off and found that the intake valve did not seat tight until piston was almost to the top of compression stroke. I ground down the end of the valve stem until the valve seated tight at the beginning of the compression upstroke. Reassembled. I now got 60 lbs compression, which is what it should read because of the compression relief gizmo, of which I know nothing, just that it was mentioned in a couple of YouTube videos by guys with thick country accents, so you know they know there small engines.
So anyway, the engine coughs to life and sounds strong for about 3 to 5 secounds when I dribble gas down the carb and pull the starter 3 or 11 times (it varies), but it will not run. I figure it has to be a fuel delivery problem, but as I mentioned earlier, the carb looks very clean.
Do any of you helpful people have any suggestions? The gas tank was clean and bone dry and I put in fresh gas. The oil level is good.
