1967 60HP SPORTFOUR THROTTLE/DISTRIBUTOR ISSUES

[WillsPride]

Sorted my fuel line leaks and replaced a leaking fuel pump diaphragm as well. Engine proving difficult to start, and on checking I notice I'm not getting anywhere near full throttle. I also note that the distributor doesn't seem to move in sync with the throttle. Should the advance and retard on the ignition only move in sync with the throttle? Or is the distributor supposed to 'spring back' when the throttle is closed?

There is a LOT of free play on the linkages controlling the throttle. If the linkage rod at the throttle cam is set to the correct closed position with the black scribe mark centred on the plastic roller, opening the throttle via the linkage rod only gives just over a third throttle, and the advance hardly moves. I read somewhere about a tutorial on something called a 'link sync' but all I could find was one based on a 1960 model V4 with a magneto. I think the 'slop' in the linkages is a real issue. Thoughts anyone?

Cheers Will.

Throttle and ignition advance do not always move together.------The ignition usually goes to full advance well before throttle is fully opened.---------Lots of times adjustments are made because it all " looks wrong " to the untrained.------Best search for a tutorial on U-TUBE for this.-----The 1960 tutorial should be the same as your later model motor.

Thanks racerone, I did find a video on a basic tutorial and have set the carb/distributor linkage correctly. Cheers mate.

No Title

Here are the instructions for an earlier model. Yours should be similar with slight variations, such as the design of the throttle rod. But it needs to accomplish the same results
