18RG - Number 1,2 and 3 all look good but i had to replace the number 4 plug for the second time it two weeks, ive only had the motor going for about 3 weeks since rebuild? The motor goes ok for a while then looses power and sure enough the no4 plug is black and wet? The motor is also blowing a bit of smoke too?
I have discovered that the number four fuel squirter (wee jet as i call them) is squirting too much fuel, i have tried changing it round with three but it still does it, i tried carby cleaner and sticking a pin in it but i cant get it too squirt good like the other wee jets.
Can these be bought new anywhere? for SOLEX carbs!
