starting valve
Hi all,
I have been looking at my starting valve and have found the hole in the cylinder block is too small for the valve spindle . has anyone else found this too?
Did you just open the hole out to the required amount?
I dont want to start drilling until I had a bit of advice from others in front of me
Thanks
Kev

Re: starting valve
Yes drill the block, I'm sure there should have been mention of it in the words. I think it's about 6mm. Cant really come to any harm, the hole is simply for the spindle to go into when the button is used. You do need to give the ball a really good whack in a vice or something to get a seat that seals, this is the problem with the valve leaking and seating it well saves any issues with it letting by and causing run on.

Thanks for the reply Kev,
Hole now drilled and valve in place
I have seen before the notion to swap the spring for a stronger one is that advisable or is the stock spring ok?
Thanks

Re: starting valve
Hi Kev,
I went for a harder spring, but that was because I had not seated the ball correctly, so the original should be fine. If you get a spare ball bearing (obviously the same size) and give it a good whack in the starter housing so it leaves a slight bevel on the edge of the hole and then re-insert your original ball bearing it should seat correctly.
As Kev has said many times in various threads the starter is a pain in the backside for passing if not seating correctly, so make sure it seals.
It took me several attempts to get it right, but now it works a treat...
Cheers,
Brian

Re: starting valve
I replaced mine as I lost it in grass ona field!! It may have helped to seal it better but Brians comment about seating it well is the answer. It is a great asset once it works and saves any pulling on the flywheel as is often seen at rallies.
