yes ill have to try this ...but it seems like its bogging a bit half throttle needle is in the middle slot . it would be already too rich ?
-
ok thanks
-
timing is at +4 ... don't really have access to race gas but maybe avgas
-
yes premium pump gas (91)
-
no tors ... motor passed leak down test and compression 155 psi ,squish is at .042 , sea level . its blowing o-rings and backing out plugs
-
yes stock carbs
-
how would i go about tuning it? ... a plug chop wont tell me if its lean on the needle
-
Is it possible to be lean on the needle but not on the main ? like it would be slightly detonating at half throttle but at full throttle be fine.
-
93 pump gas cant figure it out?...
-
22 cc domes ,4 mill ,155 compression .squish in the 40 range

ill get pics tomorow ...yes it was torqued properly ,ive already had issues with deto and plugs backing out before and blown o-rings . so i installed a thicker base gasket and it solved the plugs backing out . and now its still blowing o-rings and a piece of dome
-
its not melted off ...the domes seem fine except that broken part . these were domes cut for a 4 mill
-
it is a dome with a o-ring groove ...didnt put that much grease i would think . piston and cylinder are fine but the o-ring on the other dome was starting to break up at the same spot above the exhaust port...ill try to get pics . bore is 64.5
-
broke a small piece of the inner lip that holds the o-ring in place ,just above the exhaust port about 1/2 wide . what couldve cause this?

ship to canada?
-
piston sticks out of cylinder 0.081 inch or 2.06 mm ... is this about right for a 4 mill?
-
pretty sure cdi is stock
-
thx for all the info/advice guys ... getting new domes would probably be the best solution . Ill wait to see what jeff has to say .
-
yes i did .

jeff at Farm and sand Toys.

Alright thx!

Well race fuel would be a last resort because its expensive and not readily available . would a thicker base gasket be an option or would mess with port timing? or just larger domes . We have a local airport nearby maybe they would sell some avgas .
