How do I reference and include the quote I am replying to.

Instead of clicking "reply" click on "quote" in the message you are replying to.

No, I do not bring the throttle back after priming.

Do you prime at full throttle? What throttle setting do you use for starting?
Yes bring the throttle back after priming! This is important!

If you do not do so the fuel runs right back into the tank or fuel lines.

When you close the throttle this slows down the fuel movement preventing the fuel from siphoning back out.

Yes you prime at full throttle, then immediately bring the throttle down as you release the carb or exhaust.

Re: Throttle

Initially I adjust my linkage setups so that there is a 2-3mm opening visible in the carb with the throttle all the way DOWN but the trim set right at the middle.

Then with the plane turned on, I'll take the trim leaver on the throttle all the way up, I'll take the throttle all the way up, then prime the engine.

Once I've primed it, I'll take the throttle back down all the way, leaving the trim leaver all the way up... next I attach the glow plug ignitor and crank the engine with my starter. If fuel has reached the carb, the engine starts quickly.

Once it is running, let it sit for 30-60 seconds, especially on your first flight of the day, before bringing the throttle trim back to the middle.

BTW: To get the second "quote" box above, I cut and pasted the bracketted delimiters in this message...
