Carburettor - replacing a damaged carb drain screw
Permalink  
 


The forum seems to replicate owners problems on my own bikes somehow confuse

This time the problem was a rounded out drain screw on a carb.

I drilled out the damaged screw with a 3mm drill and then extracted it with a 3.5mm extractor.

The new drain screw is part number 14T-14104-00 - available here

Job done!

Impressive bit of work Mr. S. smile

Nice bit of engineering that Brian.

 Its a coincidence that I checked my drain screw only yesterday for the first time and luck was with me,  no one had had been at it as the the screw was undamaged. It came out with no problems and after a dab of copperslip I carefully refitted it.

your extracter looks better made than mine, where did you get it from?
I'm slowly working around the bike with a tap and die set cleaning up and clearing out, so my grease and slip has never seen so much action, still at least I should have faith that it will come apart if I need it to.

oh dear this thread is so relevent...me and rattlyolddt really needed to un-do our carb drain screws having fallen foul of the Ferneux Pelham 1km long ford...both bikes drowned in the waist high water and gave up the ghost...it was a tough push to the end to get them out and to try and repair....both carbs were fill of water and we had to remove them basically to ge the water out...not the type of repair you need to be doing on the road side!!

Looks like we'll both be looking to drill out and replace the carb screws...either that or avoid that bloody place like the plague! 1km long ford...waist deep with stale stagment stinking water....not good!!

CLICKY THING

Bad luck guys.

I guess its a warning to other owners that use ford crossings to check that they can undo their carb drainscrews - easier to find out if its seized and repair it in the garage!

PS The link doesn't work on my PC smile

ha ha. This does make for pleasant reading in the pub. Hertsrider and I do indeed require new drain screws, and new float bowl screws too. It was a lovely ride out until we drowned our bikes. Nevermind. Brian, your fancy three socket spanner doo dah wotsit has never been so welcome an addition to ones tool kit.

I would like to add we did leave Ferneax Pelham under our own steam. Eventually.

My drain looks almost as nice as the one at the top of the thread.

It's easy to spot in the exploded view on the parts sites, but the part description comes up as "Air Screw Set".  Sometimes with this nunber, 14T-14323-00-00, as well?

Cheap enough, $3-4 but thought I'd mention it.

Insights?

I think the "set" includes a spring but it isn't necessary.
