I recently just put the single minkuni carb on my 35hp GDSD, i was running it yesterday at the house and when i would first crank it up i would wait about 10 seconds and give it the gas to rev it up and it would kill, start it up again and it would backfire once, let it run for a minute and reved it and it didnt kill. Anything serious or am i just not giving it enough time to warm up. Remember i am new to the mod word and just wondering if this is a problem thanks in advance.

Download the HSR tuning manual. Do a little research here and you will find alot of info for the Mikuni!
