If it will start but dies under load or will barely run with blipping choke or throttle it usually means a barely visible grain of schmuss resides in the jet channel and will, at will, move to block the jet then happily return to its lair, eventually. Rebuilding a carburetor is becoming a lost art, especially with the more gentle cleaners available now. I have gotten to using an ultrasonic cleaner for small pieces. Another issue may be the fuel pump. Check the diaphragm. Use a strong light. With ozone, age in inventory, and usage a pinhole or tear can develope. Have fun. -- Tom M Theobald Anchored Payson AZ

Also check the vent in the gas cap, vacuum in tank causes similar problems Sent from my iPhone, spelling errors not my fault. > On Jul 9, 2020, at 10:51 AM, Tom Theobald via Trawlers-and-Trawlering <trawlers@lists.trawlering.com> wrote: > > If it will start but dies under load or will barely run with blipping choke > or throttle it usually means a barely visible grain of schmuss resides in > the jet channel and will, at will, move to block the jet then happily > return to its lair, eventually. > Rebuilding a carburetor is becoming a lost art, especially with the more > gentle cleaners available now.
