carby issues

Recommended Posts

Well, I've been driving my neighbours nuts lately working on the carby tune, anyway, it's roughly synched and balanced (just ordered a tool to do it properly) but strangely it running rich....

 

strangely because....it only 1 1/2 turns out on richness screw (usually start at 2 1/2-3) but the plugs are still blackening...

 

however, plug 1 & 6 are slightly white (as if lean) with 2,3,4,5 all rich.

so I'm a bit perplexed...

carbs are kitted (not sure how well) and engine freshly rebuilt...

any suggestions?

 

Also, does anyone know where to get the hold down clips for the choke cable on the carbies?? (currently don't have clips, so hard to use choke)

 

Cheers

is your distributer working properly, is it loose, whats it set at.... might be a issue to look at....

 

also are you getting good fuel pressure, or have you checked the fuel pressure first...

 

make sure these are both are 100% before working on the carbs, or else they will always be out....

Pretty sure my dizzy and points are as good as points get....cause i went through them when I had firing issues a little while back....

 

fuel pressure is definitely something I will look at, cause when i looked in the float bowls a while back, it seemed low to me.... and we didn't replace the pump when rebuilding the engine......

 

I think it may either be that or a problem with the needle.....

 

At the moment, I'm limited to studd that doesn't cost anything tho :-)

will have some re-upholstered seats at the end of the week tho!
