Drilling Jets

[Andi]

I have got a cheap set of carbs for spares which I want to play around with.

I take it the red arrow is the main jet that gets drilled out.?

Im going to try 1.65mm to start with

Cheers Mitch.

Getting the float bowls off has been a mission with 9 of the 12 screws being seized and spinning out in the middle.

But i dremeled two flat sides to each screw and used grips to free them. Think ill need to source some hex bolts out

[Mitch]

meant to add, remove the screws and fit proper ones, there bloody hard to get out, tightend to buggery,and easily knackered(yes Jim tighter than even i do them), mine replaced with cap heads.

I work on old bikes... it's standard practice to use a impact driver on them, the type you whack with a club hammer, works great.

 

Drilling jets is not really recommended on bikes unless you have a specific jet drill & a jig... better to buy new jets in the right size but on the car motor the difference might not be as critical from using an ordinary drill etc.
