So, the plug is covering the screw? If I manage to get the it out, am I draining the carb so as to fill it with the higher octane fuel?

[Alleyoop]

Yes the plug is covering the screw. I do not undertand the second question Has nothing to do with higher octane fuel.
This little motors run the best with 87 octane so don't waste your money on high octane fuel. High octane fuel is for HIGH COMPRESSION motors with lots of ponies.

Okay...the manual had said to use a higher octane, so I got confused. The manual was not written by somebody with good use of the English language. So, after I drain it, what do I refill it with?

[Alleyoop]

The manual says that but that is THEIR octane ratings, there 93 octane is our 87 octane. Now you are talking about the little 2 ozs of gas in the carb bowl right. After you put the carb back on, and connect everything back See the CURVED 2 inch piece of hose that is near where your going to drill. Well turn that up and pour 2 ozs of fuel that will fill the Carb Bowl then turn it back down. When you get to that part and are ready to start it follow this procedure to adjust the carbs FUEL RATIO MIXTURE: Print it out so you can follow it.

I will try this out tomorrow. It is getting too dark and cold to do this outside (no room in garage lol). Thanks SO much for the help. I can't afford to get a new carb nor are there any service places near where I am. I will let you know how it goes. ^_^

[Alleyoop]

Ok, If you can do it without disconnecting the Throttle cable what will help. Reason I say this folks that have not worked on motors will not reattach the cable in the same position and will throw the throttle setting off everything off.

If you can just loosen the clamps holding the Carb to the intake and the AIR TUBING and just rotate it so you can get to the plug to drill that would even be better.

Drilling out the plug is a common practice for us honda shadow folks. either drill a really small hole big enuf for a jewelers screwdriver to fit in to adjust the A/F adj screw (and it'll prevent from losing the A/F screw in the event it vibrates loose), or drill a hole, screw in a screw, and pull the plug out. all the time being super careful to not hit the needle head.

Screw in till LIGHTLY SEATED, then back out 2 (?) turns, test ride, then 1/4 turn till ya got it runnin right.

Please excuse my newbieness, but i thought the octane level was based on the compression.
ie: 10:1 needs the good stuff, 8.5:1 not so much.

[Alleyoop]

Yes it is based on compression BUT 10:1 is not high that is your normal compression for these motors. I have yet to see a 8.5 compression motor maybe a little 2.5 hp motor scoot or your mopeds. High compression your talking in the 11+ side. My compression on my motor is 200PSI not to many motors have that high of a compression and I do not need 93 octane. If it is denotating at high speeds then yes you need to up the octane, but if not your peachy keen.

I can live with that.
My 2002 Honda Shadow Sabre 1100cc is 8.0:1
My GL1200 Aspencade is 9.0:1
My 300cc Zodiac is 10:1
and the 50 and 150's are 10.3/10.5 : 1
Thanx

[Alleyoop]

Yes the low compression big jobs are for cruising not hotrodding.
