advice on carb rebuild

[jezushadlonghair]

I have a 1994 70 HP Evinrude that is in need of rebuilt carbs. I am not a mechanic, however I do have decent mechanical skills and experience, I even worked with a traveling marine mechanic for 2 years when I was in college. I'm a DIY'er and I'd like to do the job myself as I have rebuilt many automotive carbs; the rebuild itself looks pretty straightforward. My concern is with the synchronization and proper setup. The Seloc manual I have gets pretty in-depth on this part and I don't know if I have the skills or tools to perform it as described. Is this really a tough job? How would you go about doing the job if if were your motor? I'd also like to upgrade the VRO at the same time with a model I read about on another forum (5004558), does this seem correct? Sorry for the long post, I just want to do as much as I can now before the boating season begins. Thanks for any advice.

1994 i believe has the new OMS pump, not VRO, so upgrade could be done. on the carbs mark where they go, keep parts separate, remember where the jets in each one goes. here is a pretty decent instructions. http://forums.iboats.com/showthread.php?t=244013

i don't know which thread you are referring to, a link to it would help.

Thanks for the article link. Here is where I got my VRO info: http://continuouswave.com/whaler/reference/VRO.html. It looks like you're correct about the OMS. I'll have to take a look at it to see if it matches the description.

I believe you are referring to a linc n sync. My best advice would be to get the OEM service manual for that, and if you follow it step by step, it is really not that bad. Looks like alot of work though when you first read it through.

Keep the jets and the cover screw together, that way there is no chance you will get them mixxed up and put down a clean news paper to work on as a cloth can get lint in the jets.

Use a stripped stranded copper wire to clean the jets, just peel back strands until the wire just fits.

Also pay special attention to the passages betwen the idle and mid jets, again use a copper wire and compressd air.

If you don't have a compressor the air in a can works well.

Take your time and it is a peice of cake, good luck
