ours seems a little lean.
we are at 500ft above sea level.
it takes a long time to warm up-with choke on before it will run cleanly.

right now jetting is stock!

anyone else having any problems with jetting?

was thinking of going richer on the pilot and main.
i finally found the air screw-(what should it be at?)
what about the needle?
any help would be appreciated.
thanks

Having the problem with warming up. Real bad on cold mornings, like this past weekend. Any advise would be great.

well i think i`ve solved the cold start problem.
and now i have color in the plug also.

stock pilot is a 15 went to a 17.5
stock main is a 95 went to a 100

now it fires right up with no choke and runs clean all the way to top end.

I did the same to mine. It runs excellent now.

Where did you get your jets? Also anyone else noticed a lack of interest in the Typhoon? Nobody seems to be making anything for them. You can have the engine built anywhere but finding parts, is another thing.

you can find most on the parts need for big bore kits at dratv.com or tboltusa.com
