Howdy all,
I’m sure there is a thread somewhere, but I have found answers are fastest when done this way. I have a Used Quadra that looks like brand new, and was taken care of very well... Few things I need help with as I am in "new waters" with gas engines...

1.) The engine has a spring starter, question, do I need to be worried about the engine reaching the point of ignition and firing while turning the prop CW to wind up the spring starter?
2.) There are 2 Nipples, one on the carb, obviously the fuel from tank nipple , and one on the crankcase. I know gas engines don't use the muffler for tank pressure, is the one from the crankcase to pressurize the tank?
3.) I have no manual, therefore I have no clue on mixture ratio....I’ve been told 30/1, but need some educated advice. Also would like some suggestions on what brand of oil to use and octane of fuel....From others experience...
4.) Prop size, I have a JZ Zinger 20x8 and a 18x8, which is the better choice or is there a better size?[sm=confused.gif]
5.) There seems to be some sort of grounding strap on the case....is it indeed a grounding strap, unsure of where to hook it as the bolts for the engine mount are WAAAAY bigger than the hole in the grounding strap [:'(] .

Any other suggestions would be great....engine will be on a GP Patty Extra 300 25%, been told that this engine should fly her scale with no 3D or IMAC ability, EXACTLY what I'm looking for...I’ve been told like 500 different things as far as engine choice... Just want to fly her nice and easy until I can afford a better engine....Please no, “put a 100cc engine on your Patty like me," I get that it could use a bit more power, but as long as it will fly with a LITTLE extra power I’m ok with it for now..Thanks in advance for all the help!
