Re: 35hp not running good
Do the compression check first, and if OK look for:
1) Bad gas (water in it).
2) Plugged Main jet in carb.
3) Cracked fuel pump diaphragm.
4) Any air leaks or loose connections in fuel line from gas tank. Also make sure tank vent screw is open.
5) Weak coil on cylinder that is fouling out. Could also be defective spark plug that won't fire under compression.
