I'm running twin 40's, previously listed and agreed ok. When my engine is hot (thermostat open) the engine struggles and dies.
I thought could be crap in tank / filter but have checked and replaced with no change. As this happens only when hot could this be fuel evaporation due to manifolds being to hot on the head? |

It seems to me that your jetting might be a bit off. All my Type-4s with carbs coughed , sputtered and spit when warming up then ran like champ one at temperature.
I am no carb expert to let you know. But your symptoms seem odd to me. That is why the -6 has a hand throttle to let them warm up. Ignition is a possibility check you plug heat range as I got the parts counter guy slipped me the wrong ones once and it cost me a head. |
