Runs very rich with diaphram torn. This is a variable venture carburator. the piston is supposed to move up as engine as throttle is opened and air flow increases and thus vacume increases. If diaghrom is torn it does not move up more that a small amount so yu get only a small increase in air flow (little powe) but a great increase in vacumm and thus fuel flow.
God detctive work.

You can ask anything you want. Play this game. what would you do if someone offered you say - $1000. Say yes or no. If you say no. then ask , what if some one offered you $1500? When you find the spot where you say somethng like - I would thing hard before I said no. You are close to an asking price. May add a couple of hundred to that and put it on Craigs list. Main thing is to get some good digital pictures - several. Put 3 or 4 on the listing. When you get an inquirey be prepared to Email lots of good picts including close ups of any defects. That give the guy a chance to know what he is going to see before he comes to look at it.
Test rides are a problem.
I simply say, no test rides till it is paid for. Pay for it - in full, I give you the title - signed. Get on it then and test ride away. YOu got 15 minutes to get 100% refund as long as you do not breakit or damage it. Do either and it is yours. Period. NO tags. You are on your own.
Good luck.

My impact wrench has the ability to be adjusted to control the impact torque.
course it was a bit expensive.

I have no idea what you are trying to do and what your question is. Is there a question?

I would start by checking for a leak in the intake. There are several ways. I like the propane torch best. With the engine idleing, turn a propane torch on without lighting it and move around the pipe and hoses and check for leaks. Engine speed will pick up if you find one.
If not leak, try turning the idle mixture screw out a bit. What you are describing is typical of a lean mixture.
cheers
Spring is on the way

Thanks a lot guys. You have given he question enough attention to tell me that most of the cheap tacks are slow responders. OK but have lag.
But I would not call the tiny tach or JNC a "shop tach" suitable to be sitting on my Mac tool chest for professional use in servicing customers scoots. They are rather cheap and meant to be permanently mounted.
But I still have no idea why spocket says the tach I bought will not work on a 1 cylinder engine. I doubt he is taking about the simple task of accounting for the fact that the ta ch is not calibrated for a single cylinder instead of a 4 or 6. I think he knows I am smart enough to figure that out.
Nor if an instrument like a Innova 3568 will work
Again thanks
Cheers.

Hi John.
I do not disagree that an optical tach is a usefull device around a shop (and it sounds like you have a machine shop not a puny little place it the garage to fix a few scoots) and it would be appropritate to call it a shop tack. Nor do I wish to debate about the meaning of the words "shop Tachometer" I really do not care what it is called. I want some thing to use in my work on scoots that is relatively quick to move from scoot to scoot to use when I am servicing a variety of scoots for a variety of problems and I want to be able to test drive the scoots when it is appropriate to do so with an acurately calabrated tach attached (use some rubber bands to hold it in place). I am sure if you are familiar with scoot repair you understand why I need a portable and accurate tack that does not require I hold it to read the flywheel or some other revolving part while running a WOT on the highyay.
Thanks for the thoughts. I really had looked into an optical instrument but it will not do my job. I would add, If you are going to use it on an AIR COOLED scoot you don't want to run it at near full throttle long without the flywheel cover and air baffles intact for more than a minute or two.
Cheers

Sprocket. I know you know 1000 times more about these machines than I ever will and you give so generously of your time and talent I really have been hesitating to ask you to expain
But humor me please.. For all my life I have never been able to simply accept "not - it won't work go get something else" I have to know why it won't work. lol
Sprocket, darned if I know why an inductive pickup won't work on a 1 cylinder engine? Are you telling me a timing light with an inductive pickup will not work on a one cylinder engine also? Surely that is not true is it?
Enlighten me.

You are in god company and I am just going to tag along. Might learn something. I just finished fixing an overheaded AirCooled 150 - nothing but honed the old cylinder and installed new rings but - runs better than it ever has and better than most. So I am sure yours will too.
Good luck.

jct - I considered an optical tack. You have to uncover the flywheel and focust on that. Just about impossible to get a reading of RPM at WOT going down the highway.

The first line - owners. I haven't read all of you. but I have not spotted any OWNERS. So I really don't care what you non owners think. You do not know. YOu just think and repeat other non owners dreams. Funny. not a one modern automobile has a carburator. Ever give that a thought?

I need a shop tach so I thought I would be smart. Harbor Freight has a very nice looking self powered VOM with a tach/dwell function and an inductive pickup for a nice price so smarty me grabbed one.
At Idle it looks right. Reading 60 X 10 x 2 +1200RPM. BUT WHEN I CRACK THE THROTTLE OPEN THE READING CHANGES VERY LITTLE. NOT AT ALL CORRECT.
Simple to hook up. Turn it on, connect the inductive pickup in to the unit and clip the pickup on the Spark plug wire. It has selector positions for 3, 4, 5, 6 and 8 cylinder engines (meaning the pickup should be connected between the coil and the distributor) So I select 4 cyl. Since GY6 engines fire every turn of the flywheel and a 4 cyl engine distributor based ignition system fire 2 times every turn of the crankshaft, jut double the reading.
Any ideas of a fix? If not, any ideas of a shop tach that will work on a GY6? Anyone using one? Would something like a Innova 3568 work?
Thanks

It really is very simple. It is not 100% true you get what you pay for. Sometimes you do not. But is is almost 100% true you never get more than you pay for. Every scoot forum as people who will sell you a decent scooter at a fair price. They my not always look like the cheapest but they are in the long range. They first of all will not sell you scoots that have a poor reputation, secondly they will do everything they promise you and thirdly, you can bet your bottom buck they will not mislead you or pretend to give you more than they are (if they say red, it will be red), and I will bet that if you run into problems (and you would be very foolish to think you won't)they and we will try hard to help you. Understand, they are the ones supporting this forum with $$$$.
Be as careful of online dealers who do not have real brick and motor stores and are not actively supporting a scoot forum as you would a street walker who carried a sign saying "I have aids" .
I have no financial or friendship connection any of them, but I promise you if you buy from one of our forum sponsors and have scoot problems near me, I personally will load tools and come to your rescue.
