Hi there!!

Can someone please help me out??

(You`ll have to excuse my english here guys!!)

My problem is; I`m trying to start a os c-spec (ps) engine that has been modified by Scott Gray (about a year ago....) I have not tried to start it before today!!
When i run the starter with the fuel-line full open, it drowns imidiately, and i can`t get it around at all. I can get it running for a few seconds when i block the fuel line, but when i open the fuel line while running, it drowns again...
It`s a 3-needle 60K carb. on it with cline now, no pump.
I believe it might be wrong settings, but Scott Gray has adjusted it like he recommended for break-in.

Someone, please....?


Knut.

I'm quoting TMoore here from a recent thread, assuming this is a James ONeal modified carb
Try 1 turn on the midrange needle and 1.25 on the HS needle, set the idle to suit. Usually it is a little to the left of center.
How far away from these settings are you?

If is OMI carb, for break in try 2 full turn on H, 1 full turn on M and abut 2PM on L. You may want to check your one way pressure, make sure is in the right directions.

Hi!!

Today i have tried just about everything with the settings, it drowns anyhow when i open the fuel line.
I have mounted the oneway pressure in the right direction, i have double-checked that.
I think it`s strange that it starts at all with the main needle fully closed, also with the L needle fully closed it starts for a few seconds before it leans out (when fuel-line closed).
Can it be something wrong inside the cline regulator??


Anyhow, thanks so far guys!!

when mine sat for awhile, i had a problem with it going very rich at startup and would transition badly. i took the cline apart and found gelled fuel . it is very easy to take apart. four screw and the cover will come right off. just becaerfull with the small spring and needle. clean it with electronic cleaner and reasemble. that is what i did with mine. may be the root of your problems.

Ok, now i have cleaned the inside of the cline, but there was not much other than fresh fuel to find there.... No gelled fuel !!!
It has not been started since the modification was done, so it could not be any old fuel inside either regulator, carb. or engine itself.
Tried again with the Low needle fully closed and the engine starts running fine until it starts to go lean, i open the fuel line, and it drowns after a couple of seconds!!
Any other suggestions on what to do with this problem???

Contact James at OMI and get his advice. There could be an issue inside the cline itself. Best to phone him as he doesn't tend to reply much to emails.

i would call james, sound like the needle in the cline reg is not seating . with pressure in the tank , does it flood or hydro the motor when the engine is off? it should not. if the above happens, i would guess that the cline is at fault.

Hi again!!

Well, finally a good friend of mine solved the problem (as always).
He pulled the carb. out today and found that the barrel who surrounds the "cat-eye"-barrel was turned 180 degrees in the wrong direction....
He turned it back and says the engine now runs very smooth and reliable, even on a very rich mixture!!
Hope you understand what i try to explain here, my english might be a little "norwegen-spiced", you know??

Hi!!

Actually, i don`t wanna blame anyone for this mather, but i have not touched the carb. since i got it back from Canada, so i guess it`s possible to do it wrong from time to time, even for experts....
