I did this on accident with my first new build. What will happen if you use the outboard oil? I've had it running one time so far but it was dying going up hill or when I released the clutch. Also it was leaking black watery stuff from what seemed to be the head gasket. My oil and mixture are both blue, but it couldn't have been from using too much black grease somewhere could it? How would it get all the way up there? Is that related to using the outboard oil?
The outboard oil should be fine as long as it is 2 stroke oil and you are using the right mixture. No less then 20:1 on the new motor. The black stuff you are seeing around the head gasket is oil. That is the way it would look after it is burnt. Sounds to me like your head bolts are loose. Check them, and if you don't have a torque wrench snug them up but don't over tighten.
Yea that's what I thought. I had torqued them to 12lbs but it was a few days earlier. When I came home I tightened them too much and stripped an acorn nut. I ordered all new parts and reassembled it. I have yet to try running it yet. I still need to find a throttle because mine broke. The first time I used a break lever but it bent the cable a bit. It's good to know about the outboard oil. I am not sure actually which one it was because they are right next to each other on the shelf (same brand and color bottle at walmart. I'm going to try it again today after getting an o-ring for the carb and changing the pin position from 2 from top to 2 from bottom. Thanks
On my 80cc head bolts, I torqued them between 9-10 lbs but no more than that.
The instruction and maintenance book that came with my 80cc kit said to keep them at 12lbs. I got it up and running today. The first try was with the carb pin moved to the 2nd to bottom with no luck but I realized I didn't mess around with the choke at all. Later I moved the pin back from 2nd from top (pointed end) ans with a little playing around with the choke I got it running...it seemed like it was going fast with no throttle but I don't have the throttle that it came with so I'm improvising with a break lever which may be tight and giving it gas. At one point I actually got it to idle with the clutch in which is a first. I just need some help fine tuning it so it runs well consistently. I may move the pin back to second to the top like many suggest and then play around with the choke again. Is there like a set way of tuning the carb that works for most people- ie. the pin settings, choke settings, and the pin that twists in on the side? Thanks a lot
The torque specs for an aluminum head engine is based upon room temp.
