Q. Does carb have brass bowl? Does it have the see thru glass fuel bowl?
A. Has the "Glass Bowl" and the fuel appears to be flowing great.
Q. Unless someone had engine apart, timing should not be the problem.
A. Well, there lies the unknown. The bike was in a collectors "Man Cave/Garage" and was done really nice; possibly just for show; not sure how many hands have been on it, or if the engine was worked on.
I know she is getting fuel and spark; so that is why I'm thinking timing....have to read some more and see how to check, re-time.
