i have it in my MBX5T, and i cant get it to start to save my life. it just turns over with no signs of smoke coming out the exhaust. i did notice air bubbles moving back and forth in the fuel line. is that bad? i checked the glow plug and it working fine.. any help at all is appreciated.
this is just getting real irritating
if your turns out are from bottom you will never get it to start ...it may be too lean on bottom ...stock settings are
hsn 3.5 turns out
lsn 6 turns out
idle gap 1-1.5 mm
take it back stock and leave the hsn alone and lean the lsn an hour at a time until it will idle ...you should be able to get it going ...but its all been said on this thread ..just search back about 20-30 pages
