I am wanting some insight on how we might be able to create a vent line. We are currently building a 750 with the 130 and mini header tank. The video we have is the older one where there is a return line T-off from the pum back into the inlet line. We already have our wings built and they are the older version without a vent attachment in the top. I noticed that a guy named Roger was in the same situation and he ran what looked like drain valves that came out under the plane behind cockpit. We would maybe like to go that route but do not know exactly how he did that. That is really the only problem we are stumped on is getting a vent line from the mini header tank back either to the wing or make some sort of air bleed system as the vent return. Anyone have any insight or help?
"I think he just wants a lower the idle speed to test run the engine while waiting to install a propeller. "

"I ended up filing a notch in the throttle body casting where the throttle arm was hitting it. Worked like a charm. RPM was around 700 when I started it, adjusted the idle screw and put it at 1200 and it now stays pretty close to that after warming u…"
"Thanks for the compliment. Filing or cutting should work fine, but have you also looked at relocating the throttle lever? Hope you're able to improve on some of our ideas, and pass it on. "
"When I pull the throttle all the way back to idle the throttle linkage is already hitting the cast part of the throttle body that has been cut to make room for the linkage. I think I need to file or cut it back more so the cable can pull the linkage…"
"Without a propeller installed, we lowered our idle speed to between 850 and 1000 rpm by backing the idle screw all the way back. Our engine also speeds up as the temperature rises, but seemed to recall it remaining below 1200 with the idle screw ba…"
"I have started my 130 twice now. Last September just to get the oil flowing and lube evrything and tonight to get the air out of the coolant system and check for leaks. Both times, with the throttle at idle. It would start out at about 1700 rpm and…"
