1968 6 HP Evinrude need help

[racerone]

Nope------That is NOT legit.-----The CD ( Johnson ) and the EVINRUDE models had a fixed HS jet starting in 1964 year.-----They offered a factory kit HS needle.-----That is not as shown in your picture either !!!----What article said 1971 for that motor ???

The article in the link I put in response above (post #17).
It says:
" The carburetor shown below is the basic simple standard unit but from about 1971 on using the fixed main-jet style. Earlier motors prior to about 1970 had an adjustable main-jet in place of the #29 plug screw shown in the illustration below."

What's the story with the bashed up (seemingly) domed cap on the top of the idle circuit? Maybe you were working on removal when the pic was taken (#20); if it's the finished product, I'll suggest it needs to be sealed -- won't be able to dial in the mix without a tight seal.

6802R shows upas a 1968 6hp all right but that he carb is wrong.....or the name plate is wrong or switched IN fcat none of the 6hp J&E have HS needles..that I could find anyway.

and that carb color/finish seems wrong also... the finish makes it seems much older than the rest of the engine finish hence the possibility of an old carb installed... how's the hole in the lower cowl does it look drilled out to pass the HS needle and the funny knob ?

the LS needle should be real pointy not conical !

I know it looks ugly, but I replaced aluminum cap with new one after cleaning, tapped it with the punch to expend and then put some black gasket maker silicon on the top just to feel more confident that it is sealed...

 

[oldboat1]

dunno. Looks like a job for super glue or epoxy, maybe nail polish.

 

[Crosbyman]

see carb picture of pointy LS needle and if you open up the LS drip chamber under the ugly cap you should see the needle protrude pass the wall's edge inside the chamber .

so the question remains... where did the carb come from ?

 

[oldboat1]

Those jam nuts on the needles need to be snug against the carb body -- loose enough so you can make adjustments, but tight enough to keep the needles from wobbling around with engine vibrations.

 

[Crosbyman]

and the 6802R does not have a hole on the face plate for a HS needle...???

 

[oldboat1]

The high rpm described in your first post indicate lean running, imo. Its similar to unhooking the tank to run gas out of the carb -- rpm increase just before engine dies for lack of fuel. You want the lean effect when adjusting a carb, as that indicates the sweet spot (absent stalling).

Exactly how I do it....

Color came after soaking in PineSol and washing with carb cleaner.
Before it was usual.

I attached pics of needles, LS is top(right) one.
Also, manual I am using with carb pic that is exactly like mine.
I am still thinking, is it possible someone grinded tip of HS needle (but why???).
I wish someone reading this thread had one to compare.
It is not really clear from diagram how it should be.

The 68 model came with a FIXED high speed jet.-----So someone was working on this motor.-----Perhaps wild guessing and installed a different carburetor.-----All bets are off.------Trouble shooting ( and it is simple ) will find what needs to be done here to get the motor in good condition.----These motors run so nice and slow that you can stop one idling with your bare hands.-----Then start it again with bare hands and giving the flywheel a spin !

What would you do at this point?
I am stuck.

I was not planning to spend a lot of money on this old motor, but now it is a quest. Do you think getting parts # 15, 42 and 43 will bring carb back to working original configuration or do I need different body for that?
Do not want to throw away another $50-60 .

bad hobby if you do not want to spend $$$ ....

try the AOMCI site classified ads search ebay for a 6802R or similar carb for your 6hp it will be cheapest smooth running 6hp you can buy for an extra 50$ compared to a buyng a recent model.

LS needles are pointy real pointy to enter and close off the supply hole to the LS chamber

 

[racerone]

Hard to believe this saga I say !

Honey, how did you get on my forum??? ,
(my wife thinks I am crazy).

Crosbyman, but your picture shows HS needle with cone tip like mine, so it was not grinded.
I checked Ebay and found original OMC manual for this specific model. It was not there a few weeks ago. Ordered it. They are the best comparing to generic manuals. No luck with carb parts so far.

 

[andreipou]

Here is pictures of the holes for needles.
Bottom one does not have paint traices as the top one, so most probably it was drilled by someone.

I wonder if they just screw in HS needle to existing threads. This way I can put back the orifice if get it.
Otherwise it is a lottery...

 

[Crosbyman]

i hope the manual helps but... these are simple motors ...aside from problems with the innards the rest is just about everywhere on the net .
