Good stuff. Two tips from today:

1) Redo the cheesy bullet connectors for the wires to the CDI pack. They barely make electrical contact. I temporarily crimped mine. Works fine, but will make some nice HD connections in the spring.

2) Totally ignore the carb instructions on the Chinese kits. Put it together logically. Don't even look at the pictures!

Find the norman post and use it instead of the directions for the carb and ask questions

If you just gotta work over the mainjet by soldering it closed and redrilling may I suggest a set of these drills and pen vice. I got the vice at a hobby shop and the metric micro drills at a gun show.

Not sure if I gave this tip or not but here is one for those of us who are clutz types. During all my throttle troubles, and there were many, I got the silver washer behind the needle sucked into the engine, (don't ask and I won't tell) anyway I had to have a replacement. Of course there is no such thing. HOwever there is a flat washer that fits the cylinder perfectly. I'm not sure if it is an 8 or 10 but I think 10. Just have to grind a corner off for the cable to pass.

The clip on the needle is available from a good auto parts store. A number 4 finishing nail is almost the exact diameter of the needle end. It is just a little bit fatter but nothing you cant correct for. So you can carry one of them to the auto parts store for the match. That is if you dont trust yourself to carry the needle, I didn't.

Eve if the new clip is smaller than the orig it will block the hole in the bottom of the cylinder just fine and if the clip looks as though it could work itself through the washer (if you had to use a generic one like I did) you can cut a bit from an alum coke can, drive a nail through it and make a second washer to slip under the steel washer. A number four finishing nail and you have a perfect fit.

My throttle cable now has only one end the small one. I'm thinking that if it goes bad, i can grind the end of a regular cable down to make the smaller end of the throttle cable saving me having to try to find one like it.

So it looks like most of the small easy to lose parts can be replaced. The needle I'm not sure of. Does anyone know where one of those could be found.

I had no idea there were such things. It's good to know they are available and where thanks for the info. If this needle doesn't work since I bent it and then straightened it. I'll get with you about one. Guy who sold me the kit had nothing but a whole carb.

I'll go out on a limb and guess you could go to the local M/C shop parts counter and ask if they have anything that may match or come close. Some of those guys are really helpful and some are a royal P.I.T.A.

Or....you could contact one or more of the major dealers/sellers and ask them to contact "thier people" and have 'em send a box of 'em.

I am not really anything like a mechanic so forgive me if this is a stupid question, but would most needles have the grooves in the top of them. Like I said I know nothing about carbs in general. Probably from the fact that I installed my throttle wrong TWICE you could have guessed that.

thats a good idea as most of this engine stuff can be hard to find or a pain to track down.
