The engine fins are all clean of grass and debris, The gas is new and filtered and I checked when mower is tilted almost 45 degrees gas still flows out of fuel hose freely. I also even shortened the fuel line to be sure the tank is always higher than the carb.

sc621 Cub with Briggs engine. Stalls out when tilted to left.

Tank being filled to the brim makes no difference. The slightest slop stalls it out (20 degree), but only when tilted toward muffler side.How low is the fuel in the tank and how steep is the incline you are going across? These fuel tanks have the fuel feed nipple on the right bottom side. When the engine is tilted or inclined to the left it may be starving the engine of fuel.
Look for the carb float height being set too low.Tank being filled to the brim makes no difference. The slightest slop stalls it out (20 degree), but only when tilted toward muffler side.
That's what I'm thinking. I'm going back to the first part I changed. I keep thinking carb. I'll let you know what happens.Look for the carb float height being set too low.
Can't adjust the float on this carb. Plastic float and tab. I'll have to find another carb to try, but that may not be easy as they are no longer avl.That's what I'm thinking. I'm going back to the first part I changed. I keep thinking carb. I'll let you know what happens.
Yes you can. Think about what you wrote again. Plastic float and tab. Think if you had NO other way to fix it. Like the guys on Cuban Chrome or Pakistani Truckers on YouTube.Can't adjust the float on this carb. Plastic float and tab.

Okay heat gun and a small prying device. GENTLY heat the tab. GENTLY tweak the tab until she moves. GENTLE and SMALL movements here. Just WARMING the tab is all you want. It can be done.
Good news guys! I just finished mowing, tilting this mower at 45 degree angles and never once has it stalled out. Yes, it all went back to the carb. I opened up the bowl to adjust the float level only to find it had a plastic non adjustable float. Then I started thinking how could a new plastic float be so out of adjustment, unless the bowl was sitting too far down. That was it! The gasket was too thick, almost by 1/16" and didn't seat well in the bowl causing the bowl to set too far down from the float.. I installed another thinner gasket like I have been used to, made sure it fit well into the bowel trace and tightened it well.
After installing carb and priming, it started on 3rd pull. I tilted the deck to 45 degree angle and it never sputtered or stalled holding it in that position. Lesson learned. No mater if the part is new OEM or aftermarket it should never be overlooked as being defective.
Thanks for all your help! It really got me back on track.
