Kitty Cat Snowmobiles

I will take some pics and post them. The marks are nothing that prominent, they look like nicks in the alum.
I did get spark, now to try and start it. I am still not sure on the timing and point set up probably just luck. I do need a gas cap that will fit the old metal tank, nothing I have tried so far fits, any ideas?
Again MANY THANKS!!!

For the points you can put a .018-.020" feeler gauge between the points contacts and move the points until the plastic tab touches the peak of the cranks cam lobe, while holding the points in this position tighten the points mounting screw.

For a gas cap, you might want to remove the tank and take it to a small engine shop and see what they. I think an inch and a half or another old briggs or tecumseh cap might work. If you find one post the part number. New fuel line and a filter could also be picked up there for some cheap insurance.
