RB WS7II over heating
How many shims are supposed to be on the WS7III standard plug?
I'm having trouble with my ws7III over heating i feel that im running it rich but it still pushes near 300. Any ideas?

If you are running 30% you are supposed to add one thin .1mm shim. You do not have to it will still run fine. Sounds like you leaned out your bottom way too much. Fatten the bottom maybe half a turn, or back to factory if you know what that was. Run it and get it really close with the top needle then just clean up the bottom. I never turned my low end needle more than 3 hours from factory.

i have 5 and 1/4 on the bottom and like 3 on top... its pretty close to factory.. I asked about shims because i added one and i got this engine used. so how many shims come stock on the engine..

running an odonelle 99 plug losi 30% fuel.. i just added a .1mm shim before all this and its still hitting high temps... I know that its not too rich.. but i have it cranked up on the needles to where it wont run if i got any richer. i felt i had clutch problems but i dont know if that relates to it. just a lot of clutch slipping.

well im not sure if i even have a clutch problem =]... but im picking up some shoes and just rebuilding anyways and probably seal up the carb.

I was having a problem with heat on my RB. i could not get it under control until I got the lsn set correctly. Place hsn back to factory maybe 2 hours rich and work the lsn until engine is running with temps in the normal range. Normal being about 200-220 closer to 200. Once you get the lsn set you can practicaly adjust the hsn needle and judge temp by the hour of turn. I can now literally turn my hsn and know what temp the engine is within 5 degrees. The other thing you may want consider is. You bought it used can that be the problem?
