CARBURETOR FUEL QUESTION

[joedrum]

ok the 80-81 ignition set up has to be the most weak set up of all oldwings id say ....the 82 1100 wings and 83 had a resistor cause the 80-81 1100s had so many problems with heat ....hondaman .com is the place to go if want some real help on the stock ignition set ups by honda ..as to right them from there poor design

Just so you know the 80-81 has different Ohm coils then the 82-83 but all years have 2 ignitors. The 82-83 has a resistor because the resistance of the coil changed to keep spark igniters from overheating.
All coils interchange but if you use the 82-83 on a 80-81 you need to use the resistor so the coils ohm out the same as the 80-81, 82-83 coils on a 80-81 can be considered an upgrade with the use of the resistor the igniters will run cooler.

Ok I have not changed anything items or anything. Execpt pulled all plugs.
I have cut the bk/w wire which is joining 2 spark units and coils. I have 13v going to coils spark units and Still no spark. I have a jumper wire 12v from battery to spark units and to coil and no spark but 13 volts on all the items.
So doing the above I did away with key switch,kill switch.
So I thinking now that its the pulsar.
I have tested wires from pulsar plug motor side to spark units and no breaks in wiring.

Single carb back on it today. That honda carb is running way to rich.
The no spark problem way in the main wiring harness.

That's sounding much better!

 

[slabghost]

Sounds real good to me!

 

[auctioneeral]

I'm going to try some fine tuning tomorrow on the single and see how I make out.
I give up on the honda carbs. for now.

Ok after close looking at 4 carb rack I think I found problem with running real rich.
The 4 slow idle jets small hole all measure different diameters. They range from 22.5,27.0 29.5,31.5 inch. That was by using jewelers drill bits and then measuring diameter of the bit.
I know the jets are #35,. Do they consider that #35 inside center hole diameter of jet. What is the true inside center hole diameter suppose to be.

 

[slabghost]

I need to locate my bits. I really don't have any idea what the sizes should be. But I think all of them are supposed to be the same.

 

[zman]

The jets aren't actually measured by size they measure them by flow so drill size would not be correct unless you are using mikuni/keihin drill bits that are measured by flow size. It does sound like you have some variations there.

 

[joedrum]

.035 is hole size stock.....

 

[auctioneeral]

Ok guy's. Call me screwy or nuts....
But I worked on the honda carbs and reinstalled them.
And guess what no smoke no running rich. The thing runs like a great running motor.
I'm very happy with it now. I did sync. carbs but would like to find somebody to check them out.
Took it down road and runs great.
You ask what did I do to fix rich running.
Installed 4 brand new slow idle jets.

:yahoo: that will do it ...glad your happy

I'm very happy with it now. I did sync. carbs but would like to find somebody to check them out.

That certainly sounds better! I would be glad to take a look at the sync! I actually have a motorcycle run in the morning down in Hammonton. What is your afternoon looking like?

 

[auctioneeral]

gerry pm you

 

[joedrum]

i finally got to see the vid ...doing rather good for stock carbs ....but it sounds lazy hopefully a good sync will fix that up some .....

 

[mcgovern61]

Pm back Allen! I will bring some tools too!

 

[auctioneeral]

accelerator pump I have fuel spraying out on the outside of the carb body where that long rubber pc. slides over accelerator shaft.

I'm trying to figure out why 2 pics of the same part were uploaded :headscratch:

I don't think that boot seals gas. Well maybe it could some but leaking gas I'd say bad pump diaphragm or maybe not lined up good on the cover.
