how do I get the engine back together By seanstr (Read 2,834 times)

yeah a lot of the time you have to file the ring "end gap", I never did because i was just refitting together the same top end after modding the head.

[seanstr]

I have a 150cc, the cylinder measures 66mm. How big should gap be

[seanstr]

Ok, I have done the calculations, I was over cautious. They are correctly gaped. it dragged some so what do I know

[seanstr]

They are fine, I'll start putting it back together tonight, & tomorrow, etc, until it's done.

I need paper gasket, broke the one I had

[seanstr]

Ok, tomorrow mourning, I'm making a paper gasket for the broken one out of a cereal box.

[seanstr]

Gasket made, starting the careful re assembly of the engine Thursday.

Good luck Bro
And before you hit the start button turn it over by hand several times to make sure nothing is out of wack. Don't forget to adjust your valves I would set them both to .004 inches.

I'm setting then further out, I think it was set at .006 for intake, & .005 for exhaust, compression test said 185, that was too high, probably why compression finally died

[seanstr]

OK, so I bent the crap out if the c ring that you put in to keep the pin (metal shaft) that keeps the piston on the rod. I'll need a new one.

[Alleyoop]

You put one end of the C clip in the grove and you then work the other end so you can get the pin just inside then you can push the rest of the pin into the grove.

I didn't that, I'm going you go outside in a bit a look at it. Maybe it isn't so badly bent that I can still use it

[seanstr]

It wasn't so bad, so I got that back together, now to get the cylinder ALL the way seated, had to go to work. Will try again tomorrow.

[seanstr]

Ok, this morning I made small progress, cylinder is on, yea, now to get the rest back together, & valves reset.

[seanstr]

Got it back on charger, weeeeeee
