Wrong camshaft By royldoc (Read 963 times)

I'm getting ready to install a 83cc bbk with big valve head. got all my parts together and was doing a test fit to make sure everything is right. I don't like surprises in the middle of a project. I set the cam in the cradle of the head an it did not fit. Then I tried the rocker arm assembly and It don't fit.



Think this is the wrong cam.





Sorry about the blurry photo. The measurement is 58.59mm.



Again sorry about the bad photo. This measurement is 52.10mm.
This is supposed to be an A9 cam. All the other parts I got from scrappy had a tag identifying what they are. the cam did not. so not sure what cam this is. but it is not for a 139qmb engine.

Wrong cam?

Definitely wrong can. I just measured a stock 50cc cam. About 51.8mm

good one alley.
yes I know it's not the right cam. Question is what engine is it for and is it stock or performance. It has no markings on it and the bubble bag it was sent in isn't marked. I ordered an A9 cam for a 50cc.
What is stock lobe height on a stock cam compared to a A9 cam?
Now I got to wait till I get the right cam to do this build. Don't want to tear into the engine twice.

I called scrappy today about the wrong camshaft. The guy on the phone said I would have to contact tech support to see if they could help me fix problem. I told him I don't need tech support and the solution to the problem is for me to send it back in exchange for the right one. Or they could send me an engine to fit the camshaft. ;D H didn't think that was a good option. So I just ordered another cam.
