I have a old clinton engine, looks to be either 2.5 or 3hp
series 400.
Walboro carb, I put a new carb kit in. If that wasnt hard enough to find.
Here is what it's doing.
starts easy, idles okay. But not right.
Seems to just slowly build speed up, I open throttle up all the way and I cant tell that I have. just slowly gets going.
Now if I left wheel off the ground, it zips quick and okay.
I have found issue with rich mixture screw on bottom of float bowl.
I only have it about 1/4 out. any more and I get black smoke and it dies.
So I am not sure what may be wrong. It did this before the new carb kit. Thats why I got a new kit.
now the clutch on it, seems to work fine came off a 5 hp. So I was maybe thinking that I needed a lower sized clutch.
However, The clutch that was on it orginally did the same thing, but the brass bushing was bad causing the chain to move to much and fall off.
Maybe its me and my 200 pound butt, this will be for a 60 pound kid. but I am pretty sure that somethings not right.
Idle set at 1 1/2 ,but fuel screw only at 1/4. any more and it black smoke and dies and wont run. So i know its rich. I close it all the way and it dies.
its like I only have about 1/8th to work with.
now there is know gasket on the bowl inside middle whole, where the fuel screw comes through only on the outside of the bowl.
I put a new rubber gasket around the bowl. the one on it, looked good but changed anyway.
