In-cowl priming
Can anybody help me with this one? How do you prime an engine if you can't cover the carb with your finger? Do you have to do it before attaching the cowl or is there another way? Thanks

RE: In-cowl priming
If you can't get at the carb, assuming that the exhaust is exposed you can put your finger over the end
and prime the engine by turning it over on the starter for a few seconds with the throtle open. That will do the job for you. Nick |
RE: In-cowl priming
Yes, cover the exhaust and you will force fuel into the carb!

RE: In-cowl priming
A finger over the exhaust works fine assuming there is a pressure line from the muffler to the fuel tank. I wouldn't suggest using a starter to turn the engine over while doing this though. Turn it over by hand two or three times with the throttle open.

RE: In-cowl priming
Occasionally I will hold a finger over the exhaust while cranking to start but only for a second or three. If it still won't start, then there's a problem in that fuel is just not getting to the engine.
Look for air leaks in the fuel lines to the needle or between the needle and the carb. You probably can't see a hole/crack but tubing is cheap. Just replace it and try again. |

hi serafim
easy, just put finger over end of muffler and flip prop briskly 4 or 5 times, then remove finger and flip prop about 5 or 6 times. attach igniter and go to about 1/4 throttle and let her rip. this works fine with me good luck and happy flying; pt19 flyer |
RE: In-cowl priming
You should NEVER put your finger over the exhaust while turning the engine with a starter. A few flips by hand with the carb open will do the job. Assuming the exhaust has a pressure outlet connected to the tank you can blow things apart if you turn the engine too fast, as with a starter. This is especially true with 4 strokes but can apply to 2 strokes as well.
The method described by pt19flyer works best and with less risk. |

However, when its about putting yo finger over da hole, it's on there for an instant, something like this: The burner on your stove is on but you don't know if it's working or not. You ever-so-briefly touch the element with your finger and pull it away. That's how long I cover the exhaust hole. No boom yet [>:] |
RE: In-cowl priming
You can also squirt a bit of fuel directly into the carb and once the engine starts it will draw fuel. I have to do it like this for my on plane where it has a rubber coupler on the muffler and the coupler just expands when trying to prime with exhaust pressure.
