Triple-carburetor engine jetting and lambda

I went through a bunch of spare carburetors I have and found a handful of main jets ranging from 115, 120, 130 to 135.

Since I put the lambda gauge in the two-stroke I noticed that it’s running a little on the lean side. The engine is the 1966 triple-carburetor version. I figured the problem has to be the main jets since adjusting the mixture screw didn’t help. I had 120-135-120 main jets in at the time (that’s 1.2… Continue reading Triple-carburetor engine jetting and lambda

Just a few photos – I’m working on getting rest of the tins and body ready for paint, so nothing too exciting going on right now… Going through some boxes at home I came upon these old Saab-stickers. I think they’ll go on the “Rally”.

I installed all the stuff I was planning on (lambda meter, steering rack, engine and gearbox mounts, revcounter and a backup light). A few photos: I think between the lambda meter and the revcounter I will get pretty good info on the… Continue reading Getting the two-stroke ready for the summer

Saab 96 Rally – backup lights and gearbox

New endcap being cleaned. Ofcourse this means that all the endcap spacer rings need to be fitted all over again.

I have ordered the pistons and should get them in about a week or two. So for now it’s just doing all the minor things that still need doing. We inspected the gearbox – a few little things to fix, but nothing major it seems: And I decided to install the Works-style backup lights. I… Continue reading Saab 96 Rally – backup lights and gearbox
