Re: Theo

Could be several things. First, check to see if you have plenty of cooling flow. If the engine starts to overheat, it'll slow down. Very important.

It could, indeed be dropping one cylinder due to poor spark. In that case, you'll have to diagnose the reason.

Could be the tank vent...is it open?

Finally, when you write the subject line for a question, it's very helpful to indicate the nature of your problem in the title of the thread. "Theo" doesn't tell us much, and lots of people who might help will just skip over your post.

Cats right i almost skipped it. sounds like it's either running hot, or a coil is getting warm and failing. also could be block tank vent. my vote is bad coil. next outing check the spark on both plugs, when it starts acting up.
