Plug Chop Procedure Question

[Strawboss]

Hello All,

 

I tried doing searches about this for about an hour on HQ. Didn't find a distinct answer. I hope somebody has some experience at this and can describe the difference in the two methods if anything.

 

The Plug Chop How-to in the FAQ section does not specify that the throttle should be release when doing a plug chop. Some other information I found on dirtrider.net says that it should and that the results will be bad if you don't. See the link below and the tuning section of the article.

What do you guess think?

 

Thanks,

I've always let the throttle close just after shutting the engine down.

i have heard guys hold the throttle open after you kill it, but it doesnt make much sense. Holding it open with the motor dead but the thing stil turning is going to draw A/F in which will make a coat on the plug. I do the run and let off the gas when i kill it

Close the throttle when you kill the motor.

Close the throttle when you kill the motor.

Sounds good!! You guys are thinking right along the lines of what I was thinking.

 

Wondering if the plug chop FAQ should be updated?

Here is my revised Plug Chop How-To using the HQ FAQ procedure and some other information that I gathered. I think it might help some of the people who are trying plug chops for the first time. I am not sure how to get the plug picture to show up in this thread but I included it as an attachment. Later, Ryan
