    Ok since I found out here the SEM ignition can be sparkplug sensitive with resistor sparkplug and using them is a no-no. Which sparkplug do you use in the SEM and motoplat ignitions?

    Champion?
    Bosch?
    NGK?

    It's a bit like reviving the oil thread ! Everyone has their favorites that they have used for the last god knows how many decades. It's a bit like oil, find one that works for you and stick to it.
    Personally I always use NGK B8ES in the Husky's and a B8EV in the CCM's and other 4 strokes.

    NGK B8ES. You also have to make sure you do not accidentally buy a resistor plug cap, almost all are resistor. If it is an NGK you can tell the resistance by the number, for example an LB05F cap has 5k Ohm resistance, an LB10F has 10k ohms. The best cap for our bikes is the LBER blue silicone cap with zero resistance.

    I had a SEM ignition die after one ride years ago. I might of put a resistor plug in it. My first husky. Since the SEM IGNITION is so fragile I'd figured I'd ask. Sorry if I repeated a question from the past.

    Another source of plug caps: Check ebay for the R90 rubber cap that's offered by 'skipsoldbikes'. It has the screw post for attaching to the plug wire, is non-resistor so it works well with magneto ignitions, has a sealing clamp and is sized to fit 7-mm plug wire; $5 ea., U.S., free shipping. He also has the 7-mm stranded copper solid core bumble bee ignition wire for a buck a foot if you need it... (At least, he had all that stuff when I first posted this info...)

    That is a non resistor but it is more appropriate for a street bike, it is not very water tight, the LBER is what you should use on a Husky.
