RE: Angry with saito 100!
Check your valve clearance. Your exhaust valve is not closing or is stuck in the open position. 1. needle valve 3 turns out= Extreme amount of fuel needed to keep engine running because it is being blown out raw through the open exhaust valve .port2. Throttle high to low= takes awhile for all the excess unnecessary raw fuel to burn off. 3 . five turns or three= There is no "fine adjustment" for your needle valvewith an open valve just raw fuel flow.The valve clearance for the 100 should be a snug .0004 Good luck . Don't give up buddy these are great little engines but need pretty regular valve clearance checks. Larry
