Default Carb & prop questions

I'm about to get a new airplane gas engine, I have experience with giant scale cars using zenoah 23-26 cc.
In my zenoah engines the carb (walbro) have a primer bulb pump on the metering cover so I can pump the fuel in the first start right to the carb and no need to pull start many times till the fuel come (than I use chocke to get fuel to the engine).
Why in airplane engines the carb don't have it ? instead open full throttle and put your finger (or choke lever) ?

Second, how do I use the drill jig ?

Thanks.

Like this?
With a drill jig, always drill from the side that should fit the counterpart. So you drill props starting from the back face.

Yes, like the one in the photo.
About the drill jig, I just put the prop on the main hole of the jig ? (to center him right ?)

טולי
הקרבורטור שלך הוא למ*ועים למכו*יות כי אין לך פרופ לסובב לייצור קומפרסיה לשאוב דלק!!!

א*י ממליץ שתק*ה קרבורטור חדש\משומש ברשת או בכל ח*ות לתיקון מכסחות דשא!!
ראיתי ב RCU הודעה למכירה של קרבורטור כזה WALLBRO 20$ .

היי גדי
א*י לא מחפש לק*ות, סתם מע*יין אותי מדוע לא לעשות את הבועית ששואבת דלק גם לקרבורטורים של מ*ועי ב*זין ולאפשר שאיבת דלק קלה ומהירה במקום לסובב את הפרופ הרבה פעמים עם צ'וק עד שמגיע דלק לקרבורטור.
לפי WALBRO רק לכמה סדרות יש אופציה של הבועית הזו, זו כ*ראה אחת מהאפשרויות שבמ*ועים גדולים את הבועית.
בגל מקרה גדי, גם ללא הבועית א*י יכול לשאוב דלק ע"י פול סטרט וסגירת צ'וק אבל זה סתם לוקח זמן וא*י יכול להציף את המ*וע.
