Now Since I'm a Watchmaker by trade I had all I needed to clean this carb, but I did find out some interesting things out that made me feel like a moron and should have went back to basics from school.
#1- Never use a professional grade ultrasonic cleaner to do this it's way to powerful, I should have remembered this from school since we were taught to use aluminum foil to test the cleaner (drop a 3x3" square in the tank an turn it on for 2 minutes, take it out and it should look like Swiss cheese.) but I did learn the proper mix ratio for a good cleaning solution that doesn't harm anything with a carb.
Water+Simple Green mixed 10/1 with a tiny shot of ammonia (I know ammonia and aluminum is a no no but in the amount I'm talking about it's safe) very similar to the L&R cleaning solutions I use in my work just not as strong.
I haven't tried the Tide cleaning but I will sounds interesting.
#2- The ultrasonic cleaner from Harbor Freight is perfect for the job, low power but strong enough for cleaning a carb.
#3- I hate Humans :laughingteeth: after seeing what the previous owner/mechanic/yahoo did as you can see in the pictures it's not too bad but it makes me wonder what people are thinking?
#4- You folks were so right saying what did I have to lose, it came out pretty good and allot easier than I thought it would.
#5- Don't start a project like this without taking pics :rolleyes:, I wish I had some to show how bad it really was but I didn't so all I have is how it looked when I got it done .
#6- Being a Horologist has it's advantages (very small tools) when working on a carb.
What I found under the varnish/shellac wasn't nice but nothing that can't be replaced, typical dry rotted rubber seals, good looking high/low needles and needle valve which won't matter with most rebuild kits because they come with them, at least thats what I've seen ?
The real shocker was the float, after an hour in the cleaner it looked great till I shook it and it oozed foul smelling fuel and cleaner out (it's cracked) but still floats, so a new one is in order (but I may try to fix it just to see if I can) it's cheap and I cant repair it for the price of a new one, as a side note I never really knew what my Dad (Old Alabama Boy) meant by sour gas until now wow it's nasty !
And if anyone has a good source for parts please sound off, as it stands now I found out most of what I need I can get from Napa (Who would have guessed ?) down the road for about the same with tax as online but no shipping so it comes out less expensive, and any help with the carb numbers would be great.
Carb# 516-4C13 but it's hard to tell as you can see.
Sorry for the ramble but I just thought I would tell/show you Folks how it turned out.
P.S, If anyone would like to know more about some of the tools and supplies I used just give me a shout.
