Carb primer pull tab
After 5 years of playing with this idea I finally did it. After sitting for a few days, my fuel system always drains the fuel back to the tank. Makes it hard to start. Plugging the vent line helps, but its not a real fix. I installed a fuel check valve in the fuel line a few weeks ago, but at high engine RPM's, the fuel flow couldn't keep up. The check valve was to restrictive. So I pulled it out. Replaced the cut fuel hose with a new one. So its all back to stock.
I located the carb fuel primer. Its under the carb. See pic 1, 2 and 3 for location. I have the zip tie through it.
Run the zip tie down through spaces in the motor where it won't interfere with anything.
Drill a 1/4" hole through your engine cover, straight line shot to the lower inner right corner.
Pop the zip tie through the cowl (use a 2nd zip tie if you need extra length).
Pop the end of the zip tie though the hole you drilled.
Now, just give that zip tie a few little tugs before you start your engine. It will fire right up, by priming the carb.
If its cold outside, floor the gas pedal once, with the key on, to set the electric choke. Pull that zip tie a few times and try starting it. if it doesn't go, just pull the zip tie a few more times. Don't pull it too much, because it will flood the engine.
Fixed my hard start problem. Should fix yours, too!
