I don't know if this has been posted before, sorry if it has. I bought an extra flywheel a couple of years ago for my '86 350x and had a board member lighten it for me. When I rebuilt the engine I was too cheap to spend $20 for a puller, so I just set it aside. Now that I am going through the engine again I decided I'd change it out. I just about had a puller ordered when my friend called me to ask if I had a flywheel puller for my old 250sx that he currently owns. I told him no, but I was about to order one for my trike and I'd send it his way when I was done with it (same puller for the two). The next day he called me and said not to order the puller, he found something that works. Certain saturn cars have smaller cv shafts and they are the same thread pitch and size as the flywheel. I then checked into it and found that I actually had something sitting on my trike that will work as well, the rear axle. The rear axle threads are the same pitch and size threads as the flywheel as well, and I happened to have an old bent axle laying around. Works great. I know $20 may not seem like much, but when you have no extra $ it's a lot. Needless to say I am very happy, and I don't have to wait for a tool to be shipped that I'll use one time. :Bounce

good for you!

I had an epiphany myself tonight.

cant walk and cant get this carb to work.
as delicate as I could outside with all the solvents and compressed air, new jet kit etc still no go.

got windy and cold and had to come inside.

Sat down and got right back up. Just could not let this sucker get the best of me

boiled it up on the stove submerged in water and lemon juice and used clear that blue fuel line to mouth blow air thru all the jets.

Whoever designed those internal passages had something I certainly dont.

Pretty cool to see bubbles on a known working carb coming out in all kinda of different places

and the lack thereof on the one I need to work.

No idea why I thought of THAT!

desperation?

and a mild sense of accomplishment.

Maybe we outsmarted them just a little this time.

Thanks for the tip

You can also just get a cheap bolt from the hardware store if they have a decent selection of metric bolts. You can find the thread and pitch of the bolt you need on Dennis Kirk's site. Yes, the rear axle threads in, but how do you turn the sucker? You aren't going to be able to get a good enough grip on it with your hands lol.

I attached a pic using a $3 hardware bolt on my 200x. I held the flywheel from turning with a cheap strap wrench.

Will the bolt trick work on a 1983 200? Was just about to buy a puller but I really don't want to wait.

the 200s are kind of weird, because they have left hand threads. so unless you can find left hand thread-odd size metric bolts, no. i would just find a local guy with the puller. give him 5 bucks.

On the 200x's you can use the front axle bolt to remove the flywheel
