Engine bogs down and stalls on incline

[JohnF]

Rebuild the carb. Pay attention to the float adjustment.

Make sure the float is level not slanted

Make sure the float is not saturated with gas creating a low float level and check that the needle seat is not partially blocked.

I have a 1996 MAX II with Vanguard Twin 14HP. I had a similar problem with my engine.

At certain times, usually after either on a steep incline or going over a rough piece of land, my engine would suddenly 'starve' for gas, and stop. The engine had to cool before it would restart, and then it was still hard. After this happened a couple of times, I searched for an answer. What I found was a weird but honest weblink, and when I tried the suggested fix, it worked to get the engine at least re-started in the field, so that I could return to my point of origin. Here is link: https://www.youtube.com/watch?v=SSHk4RzC2B8

However, since then, I have totally drained and flushed the gas tank. Replaced all gas line with new, added a fuel cut off valve, and installed a new fuel pump and filter. While the problem still occurred occasionally, it was better. I then used another link and did a home 'carb cleaning'.

Since that cleaning, the engine seems to run better, and I have yet to have the 'stalling' occur, not to say it will not happen again.

However, I have found that going up a steep incline (30 degree or more) really taxes the engine and transmission, to the point that I must stop and turn around, or traverse the hill on an angle ( not a good idea).

Has anyone had a like or similar problem? My problem sounds much like the starter of this thread.
