Stripped bowl threads on carbs Helicoil guidance needed.
McCabe-Thiele (Ted):
I did wonder if J-B original cold weld (2 part) would work as an alternative as I have some left over from a previous repair job?
Bryanj:
That should be ok Ted, same as araldite i think, clean well with something like brake cleaner first and let it dry
McCabe-Thiele (Ted):
I ordered some of the Loctite 648 that was due for delivery yesterday Bryan but getting impatient so thought about the J-B as an alternative.
After more research I'm going to wait for the Loctite 648 - I've been away from the 500 for a month so another few days will not hurt.
McCabe-Thiele (Ted):
After my short summer recess I have finally fitted Helicoils to the two stripped carb bowl threads.
My first Helicoil was okay but I did not manage to get the thread as far down as I should have with the tap so the tang came off as I tried to wind it down the last bit. I have used a slightly shorter screw, Result!
Before I fitted the second Helicoil I ground off a tad more of my reamer with my Dremel. I managed an extra thread right to the end.
The Helicoil fits beautifully - so practice makes perfect proved yet again.
It's my first ever Helicoil so I am chuffed to bits & re-motivated to press on with the carb cleaning/re-fitting.
Just wondered if I ought to fit a new set of 40 jets or is there enough control with the air screws to cope with any enlargements caused by previous cleaning etc?
Comments welcome regarding jet replacement thoughts.
