runs-stops-runs-stops it does this continuously ???

My spree starts very easily and runs like this, It will only idle for a very short time, unless I hold the thottle just a tiny bit. This is wher she kind of runs.
A tiny bit'o'throttle and it runs for about a second then stops firing in the cylinder. One second more upon reving down, right before it almost stops reving it fires up again. and this process will continue for about a minute or so.

I guessing that it stops sparking for some reason or another and then starts again.

I very new to sprees my first day working on the two I bought to build one good one.

I folowed the spark wire back to what I believe to be the same thing as the CDI on a snowmobile I swictheed that out with the other I had. They were identical. But, I get the same response from the engine.

I may be completly off, let me know if anyome can help !!

THANKS ALOT,
BRYAN

sorry for the novel

if u have no airfilter/lid that will cause this.

ripps · Post by **ripps** » Wed Jun 01, 2005 8:11 pm

I had the air filter on at first, then I took it off. I thought that it might be dirty thus hindering its air flow. I took the air filter completly off and it does the same thing. However after checking the filter itself, it seems to be fairly clean.

I don't understand what you mean, could you explain ?

THANKS for the repley,
BRYAN

that type of carb needs a certain amount of back pressure to operate proberly, thus the air box.

Thanks for the info vette76.

Does anyone else have any ideas ??

THANKS,

i would do a complete carb clean. not hard 2 do and usually solves it.

If the filter is installed, and the fluctuation between rpms while running with no change in throttle is 98% related to fuel flow being consistantly supplied. Very rarely in any engine does lack/abundance of backpressure before/after the combustion chamber result in a fluctuation of running smoothly. Backpressure may cause a stall under load or hesitation, but not what you describe. If you have to play with the throttle to moderate the engine, it is fuel (clogged jet, bad float needle, bad petcock, clogged fuel line, etc.)

I had a similar experience with my Spree and the idle jet was not clear. Clean it out and make sure it is clear. You should be able to see light through both the main jet (easy to see) and the idle jet when they have been properly cleaned.

I'm betting the idle jet is blocked.

ripps · Post by **ripps** » Thu Jun 02, 2005 11:21 pm

I completly cleaned the carb. and I found that it was missing the air fuel needle. I thought trhat it would fix the prob. nope. I put one in, put it back together. Now it starts and revs a sec. or two then dies !!

Any body know what's up ??

Is everyone sure that it is not lacking spark after a few sec. I don't have a battery so I can't do the electric start and watch the spark continuously.
Is the fact that I don't have a battery the prob.? I know when a cars battery gets low the car will not run. Is this the same thing ??

THANKS,
BRYAN

Is the air screw jet adjusted properly. It should be turned out from a closed position about 1 1/2 turns counterclockwise for a 1986.
1 3/8 turns after 1986.
1 7/8 before 1986.

You could also check your throttle valve needle setting.
Which notch is it set on?
If you move the needle clip up you will get a leaner setting.
If you move it down you will get a richer setting.

ripps · Post by **ripps** » Fri Jun 03, 2005 2:01 am

I don't understand, which notch ? You move the clip ? Thanks for the air needle setting . I forgot to ask that. ANd I actually think I' working on like a 1990 somthing. Here are the #s JH2AF1211HS008629, and I have parts from a 87'

Thanks hondaman,

I am just familiar with the 84 85 86 87 sprees.
On these models your throttle valve is where your throttle cable
comes into the carb on the top. You unscrew the the throttle assembly
there. You should see your throttle needle there. Detach your throttle cable by holding unto the throttle valve and push up till your throttle cable comes out. Then push up on the needle and it will come out. There is a little expansion ring that holds the needle in place so be careful and dont lose it when you push up on the needle. On the needle is a little half-ringwhich can be moved up or down on the little notches on the needle.
Use a needle nose pliers to detach and reattach the little half ring to the setting which you would like to try.
I do not know if the later models are built like this or not.
