Remy,
One thing at a time....& you will get through this:
- If the cam is stock [ or you are not sure ], set initial timing to 12*
- If the cam is bigger than stock, set initial to about 20*.
- With the engine idling, using a torch, look into the pri barrels, look from the brass booster tip down to the blades. If you see fuel dripping, that is a problem.
- Secondaries will NOT open until choke is fully open. So choke adjustment can stop secs from opening.
Report back after doing the above.
