I was going to adjust my valves on my 400, but having trouble telling if I am on the compression stroke. There seems like there is no slack no matter what. Could it be my valves are just way to tight???? Can't get anything to slide in.

If anyone has some ideas or advice that would be great.

when it comes up on exhaust stroke exhaust valves will be open, than intakes will open as it goes down, then as they shut and it comes up with both valves closed thats the compression stroke. you can tell by watching where the valves are as you turn it, sounds like there pretty tight.

Check this thread out, procedure is nearly identical on the 400 i think.

Have a Problem?

Troubleshooting First Steps, An amazing number of problems are cured with just these two items.

1. Make sure your battery is FULLY Charged.
2. Try a new spark plug.

Search threads, Check Pinned Section. Pinned Topics Manual or wiring diagram? Manuals

Improving Search.

Better results when searching for specific information. To find threads where ALL the words, instead of ANY of the words "650H1, Carb, Jetting, Needle Jet, Snorkel" were found...Open up a search window in In the find box type without the quotes "650H1 Carb Jetting Needle Jet Snorkel" & Press return. Find threads, replies or topics by a specific member; just by inserting their user name into the search list; Chances are, your problem is NOT unique and it has been solved many times before.

Are you in a hurry to get an answer?
