Thanks. Since there is a way that doesn't involve cutting I will choose that one.

Yes, my other Volvo is red. Unfortunately it serves as a parts source now.

The silver Volvo I play with now, has B200E engine but someone removed the K-Jet and put a ZS carb on it. Most of the K-Jet was gone so I didn't even think of restoring it. The conversion done by previous owner left much to be desired, the carb itself was very worn out. When looking for the best solution I've found v-performance.com and liked the idea of Mikunis. After torturing John with lots of questions I bought a pair.

The only problem was intake manifold since John works mostly with B18/B20 engines. Finally I have found that AQ140 Penta engines were B21 based and used twin Solex carbs. This manifold is very rare piece but possible to get. After lots of hunting I got one from Ebay.

I have those carbs on the manifold now and it fit right in. However to make it work on car it still needs some fiddling, drilling and tapping (vacuum, accelerator cable etc.). What I'm missing is time to finish that and I want to deal with those #%$*! brakes and seal the engine and transmission first.
