Thanks Todd I may just try those just thinking the compression was a little low also.

Everything on this sled is original it starts on the second or third pull when cold otherwiseit starts up fine usually if the seals r out they wont start is what ii've been told unless u prime the system so you are thinking the seals vould cause this boggy issue I have at times.

Thanks for the input on this I also adjusted the choke cable and it does run better sometimes when you get on it out of the hole it really takes off then the next time it wont hardly spin the track so does this sound like a low compression issue to you guys. Thanks for any more help.

I have 105 and 110 comp.It seems like its low on power should I put in new pistons are just a set of rings. Any help

Can you tell me what is the proper adjustment for the choke cable.

What should a 440 Trailfire have for compression to run good.
