SPITTING CARB - 914-6 all stock, **** Triangle of Items **** Options

[ctc911ctc]

1970 - 914-6 All stock

Got the car off the rack after a 1 year clean up documented here:

http://www.914world.com/bbs2/index.php?sho...3371&st=100

- tightened the lugs, check one more time for leaks.......

Car started first try, backed out of the driveway and went around the block

Drive strong.....very strong......

#2 cyl-carb is still 'spitting' definitely not backfiring. Chasing this through my trusty guide:

https://www.performanceoriented.com/special-procedures-1

See "notes" section

Seems that when I performed the Lean Best Idle procedure #2 failed during the procedure......the diagnosis within the document states that either the path in that carb #2 is blocked or the jet is the wrong size - my bet is a clog......though the carbs were very clean when I got the car.

There is a little noise from the right side, that in a 914-2L 4Cyl would be considered quiet, my hope is that it is not valve noise and may be exhaust leaking......did I tighten the heater manifold small nuts????? dry.gif

Carb advice sought from those that have chased a SPITTING Carb

Unclear on the question here?

You need to resolve the issue on cyl 2 with inability to get mixture set properly.

Appearance of carbs is almost meaningless.

Need to ensure all passages are clean and clear and that idle jets are the same on on all cylinders as a start. Ensure all gaskets are OK, no missing o-rings, no excess air leakage at throttle shafts. Etc.

Thank you for the reply SH,

I was more or less looking for 'other paths' such as make certain that the bypass screw is set to.............." or other items that come from experience.

I had the carbs off, apart and calibrated floats, squirts, etc. the Inside of the carbs were remarkably clean.

I am thinking of taking the carb off and

1. looking for material inconsistencies - missing washers, etc.
2. Measuring the jets for #2 and comparing against #1 and #3
3. Clogged path - not sure what to do here, how to test, what to use.

Will follow your guidance, (IMG:style_emoticons/default/smile.gif)
