Without thinking about the switch from leaded to unleaded fuel I've been running unleaded fuel in my trikes that no longer run. They both have good compression (I'm feeling compression when I pull the cord) but stopped running.

Does everyone run unleaded fuel with out problems or do you run with a lead additive?

well, the thing with the new unleaded fuels is that they clog up the carb jets if you let them sit for even a few weeks. I'd start there.

Trikes were made after the switch to unleaded gasoline (around 71-72 the mopars went to the hardened valve seats because of it), but as of late with the introduction of 10% ethanol the average pump gas will only stay good for about 3 months inside the tank. I'd say clean the carb and drain the gas and get some fresh 93 in there and see what happens, TC...

Mechanics and manufacturers say that while a 10% ethanol blend causes few problems in a car's closed fuel system, it can be a big problem in boats, whose gas tanks are ventilated. Ethanol absorbs water from the air, which can cause a motor to lose power or stall. A solvent, ethanol also picks up contaminants from storage containers. And when mixed with non-ethanol gasoline already in a tank, the blend can form a gelatinous glob that clogs fuel filters.


vented just like our atv tanks...

just something to keep in mind when using fuel with ethanol in it.. i try to buy ethanol free premium fuel when ever i can!

The only place I know of that sells ethanol free gas is boat marinas. And expect to pay more there.

not around here... the gas station i worked at when i was younger has ethanol free premium, along with 2 other places in town,, sucks the gas station right by the lake we ride on sells 5%? ethanol premuim..


and aboutt he leaded/ unleaded.. like stated your machines were built wayyyy after the switch over, and even if they were that old the valve seats would wear after time and start smoking
