The Wanderer - Part 2

Where is the acceleration pump set at? If it is in the middle, back it off and see what happens. Sounds like it is flooding and that extra shot of fuel could be doing it. Backing the accel pump a little will cut down on the amount of fuel being shot.

Is this the acc pump adjustment. Do I move it further up or down?

 

[brianinpa]

Yes... moving the bolt down will result in a shorter stroke of the shaft and less fuel pumped in. That looks like it is pretty much bottomed out, but I found that a little adjustment went a long way.

Adjusted and still the same problem. Appears as though its starving for gas. Other than that, bike runs great !

I will check the plugs next.

 

[brianinpa]

If it's starving, try taking it to the other end of the adjustment.

 

[made2care]

All 4 plugs were fouled. I forgot to change the plugs after the single carb install. Could have been fouled from stock carbs, at least i'm hoping that.
Took her out for a run with new plugs and opened up throttle. No problems, she took off fast with no hesitation. Plugs were the culprit. Will check plugs after a few more runs.

P.s. for years i have been tightening plugs too tight i guess. Manual calls for a just 1/4 of a turn after finger tight . Oh well.

 

[made2care]

:help: Well, shoot. Plugs are fouling. Dry black. Too rich i guess. I will have to fiddle with air/fuel screw some more. :head bang:

 

[brianinpa]

It sounds like the idle is set, so don't be afraid to change the main jet size. What size is in there now? With this carb, I think it is a fine balance between the main jet size and the acceleration pump setting that gets rid of that bog at higher rpms.

Whatever size came factory on this carb.

From DKL's post, he used the same carb too, all he did was set the 2 screws out 2 1/2 turns and he was good to go.

ok ..dont get discouraged ..this is the start of dialing it in ..firstthing id dois bottom out the accelerator pump linkage ...as mention earlier id clean the plugs and put a good house fan on the radiator and idle it for awhile to see how the plugs are burning at idle ...if that seems good then a main jet change can be done ...but actually a bike seems to run at lower rpm most of the time so its very possible it fouling at idle and low rpm ..anyway this is dialing in and getting to know your carb

I'm going to be patient. Keep telling myself i just got the bike for $200 and its running. I will try the other end of the accelerator pump linkage, just tried the one end so far, so i will set it to the other end to see what happens.

Also, could a vacuum leak be causing the fouling?

 

[slabghost]

Vac leak usually causes a lean condition at one plug at least. So it's a safe bet you need to dial in the jets.

What size jet did you go with?

Here are a few things That might not be anything. Might be my OCD kicking in.

The carb came with no instructions. When i went back to my ebay purchase , i noticed the online instructions said the oil channels would be blocked without cleaning. I did not know this.
Also the carb is for a dual port engine, not single port.

thoughts?

 

[brianinpa]

Idle is around .30mm. Main is 1.35mm

I would think the fuel that has been put through the carb so far has cleaned out the carb.

True.

Where might i find these size jets?

Looking online, found a solex 135 and still looking for the 30

 

[slabghost]

You have a "dual port" engine. Two ports on each head.

 

[brianinpa]

I made my idle jet which is why I say around .30 MM. I soldered the hole shut and used a micro drill bit set that I bought from Harbor Frieght and slowly increased the size until I liked what I had. I quit when I was using the drill bit that Harbor Freight claims is .30 MM's. I just don't trust their measurements.

THis is where I got my main jets at, and they also have the idle jet...

[made2care]

When i step back and take a look at the situation, i realize there are many variables involved here and I am no mechanic and don't know half the stuff I'm doing, maybe even more than half.

variables:

Coils might need replaced, have spark but might be weak

-has harley sportster pipes

-have never done a compression test

-might have vacuum leak

-might need to re-jet

I'm taking a break :salute:

 

[slabghost]

Break is good. Pipes should be no issue at all. Weak spark is a possibility. Compression won't likely cause rich condition. May oil foul plugs if bad enough though. Vacuum leak would make it more lean not over rich. Re jet? Bingo! Probably where you are.
