Suzuki SJ10 carb conversion
As per popular advice I'm changing the Suzuki carb for an SU one taken
from a 1000cc mini. I'm having problems making it idle. Any ideas? Cheers! |

What is it doing at idle?
Does the dashpot have oil in it? Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's Canadian Off Road Trips Photos: Non members can still view!

I first think engine run on from a carbon build up in the cylinders.
Did it have run on with the old carb? You can get top end spray that you shoot the whole can in the intake while keeping the throttle manually up so it doesn't stall. This can do wonders for that or a cup of water can be sucked in to a vacuum line on the manifold seeing as you can't slowly pour it in like with an updraft carb. The carb should have a 'button' on the bottom that raises the internal piston. When you push up on this, the rpm will raise if it's too lean, bog if it's too rich or raise a little then mellow back if the mix is just right. The piston pot has to have oil in the center under the screw cap. Up to the ridge I think it is. We used to use sewing machine oil, but that spits out fast, I think 10W30 was called for.

Oh, a little rich and a leak at the intake or exhaust manifold can also
make a backfire. Mike Mike Romain wrote: > > I first think engine run on from a carbon build up in the cylinders. > Did it have run on with the old carb?
