190 carb 2L

[190carb]

Hello there everybody, i could use some help;

I have a 190 carb 2L and it has done 173K, but runs fine - mainly? - When idling at a junction (or when ever) with the clutch down the idle speed will drop and normally the car stalls. Also when there is heavy electrical load the revs will also drop. sometimes its fine however more often than not its just plain evil :twisted:

One more thing, there is often hesitation when accelerating through the low rev range 1000 - 2000..

Can any one help does any one know how the idle is controlled on a carb (strom 175)? Does any one think that using a engine flush to clean out carbon deposits will help or will it harm my old engine??

HELP!!

Thanks guys

Do you still have you 190 Carb model?

for the hesitation

i would check/replace the following

spark plugs,

distributor cap

rotor

spark plug leads

i changed the leads on my car and the hesitation stopped

Try changing the diaphragm within carb

Sounds like the vacuum diaphragm as SeanB suggests.
