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

Getting the two-stroke ready for the summer

The lambda meter (fuel/air ratio meter) and the small revcounter that I will install under the dash.

Just a quick update. The two-stroke is pretty much ready for the summer. 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

But I also think that this is something that would interest other two-stroke enthusiasts. Triboron is a Swedish company and had… Continue reading Triboron nano boron two-stroke lubricant

My trip to Trollhättan

Time to leave Trollhättan. A little photo opportunity to remind us of the airplane heritage of Saab.

The trip to Trollhättan started on Wednesday from my garage at Nokia, Finland. I drove my two stroke to Turku where I met Tikkis and Sami who brought the V4 Rally on a trailer. The V4 was offloaded (we left the trailer at a fellow saab club member Tero Setäläs shop) and we continued on… Continue reading My trip to Trollhättan

Saab two stroke trailer hitch

I have this trailer connector tester which makes checking you have the right wires in the right place easy.

I decided to put a trailer hitch on the two stroke. Basically just in case I need to take something bigger to a club event. I had an original Saab 95 trailer hitch that I did not need so I exchanged it to the 96 model with a fellow Saab Club member Vesa. It had… Continue reading Saab two stroke trailer hitch

Fuel system repair on the two-stroke

Grinding the port edges with a compressed air grinder. Wish I had smaller hands...

As I promised in the previous post – here’s a bit more info on what we did to fix the fuel issues on the two-stroke: So – as we suspected the fuel intake pipe in the fuel tank had become corroded during the long period the car was stored outside before I bought it. On… Continue reading Fuel system repair on the two-stroke
