Carburetor issues

OK, sorry it took so long. Here are the results, though I am not certain I got exactly a tablespoon of oil in each cylinder.

Here are the results:

:arrow: Cylinder 1: 185
:arrow: Cylinder 2: 155
:arrow: Cylinder 3: 155
:arrow: Cylinder 4: 185

 

If the shims are all in spec' it would indicate that 1 & 4 need attention to the bores / rings. Maybe you didn't get the same amount of oil down 2 & 3.

 

BUMP

 

Wadaya mean bump, Rick, did you unlock it?

 

I may have locked it in error meaning to click on: "Stop Watching This Topic"

Sorry.

 

OK, after all this I may have found my problem. I decided to go back through the carbs again and check the cold start needles as I hadn't checked them before. Well, long story short. I found that on carb 4 the cold start needle had the retaining nut backed out slightly and the spring was rusted and broken. So, it has to be inriching the fuel in that cylinder. Now, if I could only find the spring locally to repair it.

 

Problem solved! Rebuilt carb 4's cold start and no more stammer/stutter. Man, a $2.00 spring gave me all this trouble ! Well, on the upside, I now know the carbs like the back of my hand as I pulled them apart in every way except seperating them one from another.
