Throttle Response Question

[STLYamWar]

When gunning the throttle in gear it delays about a 1/2 to 1 second. Any thoughts?:???:

Is your accelerator pump stuck?

 

[STLYamWar]

That's very possible Frit. Didn't think about that but it has been stuck in the past. Thanks I will check. What can I do to keep it from sticking in the future?

 

[STLYamWar]

Grease the rod or replace the spring?

Replace the spring with one from a clicker pen.

 

[STLYamWar]

Will do lb Thanks!

Yep, use a clicker pen spring. I lightly cleaned my plunger with scotch bright to remove the build up that develops on it. Worked like a charm. If you haven't done it yet, you may want to try doing the valve stem cap trick also. I didn't do it but after swapping springs mine worked great and had NO throttle hesitstion.

Could the spark plug be the issue too? The reason I ask is cause I just received my Iridium spark plug (thanks Beastmode for the type of plug needed), replaced it, and throttle response is dead on. Although for the hell of it I might just go ahead and check the accelerator pump.

the more you check and upgrade or service the better

It was the spark plug. Pulled the carb, checked the accelerator pump and is operating correctly.

That NGK Iridium IX will do ya good for a long time:tup:

 

[STLYamWar]

Ya I can already tell a difference. Throttle responds right away believe the old plug was way over due to be replaced. I would take it out every now and then to clean for the past 2-3 years lol.
