Triumph cuts out on acelleration?

[MARIO MEDEIROS]

Have a 67 500 that when you are on the gas it cuts out and spits and sputers out the exhaust but if you roll on the throttle east it is ok?It did not do this when i put it away from last years riding only just hapened when i went to fire it up last week.It has a boyer,and a new pwk carb,which i took apart and blow it all out,the battery is ok,ground for the battery is ok,only thing i have not tried is replacing the plugs and maybe replacing last years fuel which i did add stab. in the tank.Any other things i should look at?Not sure if this is a fuel or electical problem.Thanks

Also i run ngk b8es plugs,what should my gap be? also should the plugs need to be br8es? does boyer need a plug with a resistor? i run the boyer mark 4 thanks

My T100R did this last week. It always happens to me if the bike runs too rich and affects the plugs. Pull the plugs, bet they are very black. I run B8ES's also. New plugs and carb adjust will prob do it. I don't know for sure but thing this is a greater issue with duel carbs.

My money is on "last years gas"

[MARIO MEDEIROS]

Well last years gas it was!!!!!!!drained the tank,put in new fuel and plugs and it runs great.Also found that last years gas ate away some of my liner which i had done 3 years ago,i have heard of todays gas doing that on other guys tanks also,shit gas today!
