Well i have a Thunderquake with 24.7 engine and when i pull the pullstarter too crank the engine there is no compression. AT ALL. When you pull the pull starter its like pulling a kite string out of the palm of your hand. It's not turning the engine. Whats going on?Is it a serious internal problem?
Thanks in advance.

do you have a glow plug in??! the 24.7 doesnt come with one.

Well 1st of all check and see if all your backplate screws are tight, sometimes that may be the problem. If its not that dheck your on way bearing.

I wasnt trying too start it. Just checking its compression. And yes the engine has already been broken in. I bought it used..

Hi, if the engine is not turning over when you pull on the cord then most likely thhe problem is in the pullstart it's self (broken pull start?, like a one way bearing maybe)

u need ur glo plug in to get compression

Wow no one even offered the obvious answer...the one way is slipping. Remove and clean the one way with nitro cleaner or denatured alcohol, re-install and all should be fine.

One way bearings tend to slip after break in due to the extra rich settings.

lol [&o] Thankyou for your answer binary. I got the one way out and cleaned it off really well and it works fine now.

You must be blind? Did you not see my post? or The Boss's post?

Well i made a little spelling mistake on mine i accidently said "dheck your on way bearing" i ment "check your one way bearing"

Yeah i see that now...was just thinking that should be the only thing mentioned for something like this...my bad.
