Brison 104 Twin question
I just aquired a used Brison 104 Twin and have a couple questions. Where can I get those tiny spark plugs. They have the same hex as the glow plugs. I also noticed a hose fitting on the bottom of the crank case. What line is going on that? Your help is greatly appreciated.

RE: Brison 104 Twin question
You can change over to the larger plugs and they are a lot cheaper .
I would call C&H ignitions and get a price on sending in your ignition and changing it over , unless you need the smaller plugs to fit it in the cowl..
I ran the small plugs for quite a while because i needed them for a tight fit , they worked well but were expensive to replace (about 16.00 each as i recall).
As for the hose from the crank case . It is probably for a smoke setup (old diaghram type that uses crankcase pulses to pump smoke fluid).
You need to block this off as it will cause a lean run condition (vacuum leak) if left open . It would be best to install a plug in the crankcase instead of
trying to block off the hose .
