 Now i know this aint a 138  grey motor but as i have a red 186 in my FC maybe  i can ask these (probaly easy questions to you guys, but to a non mechanic person like myself they are hard) firstly what grade of oil should i use and how much does the sump hold? second what spark plugs should i use and what should the gap be? and thirdly what points should i use? and lastly what are the best leads to use/buy?. Again i know these questions might seem simple to most of you guys but i am a novice at this,
